Book excerpt: "Next-generation NASA missions, such as the LUVIOR and HabEx concepts, require single photon counting large-format detectors. Charge Coupled Devices (CCDs) have typically been used for optical applications in similar flagship missions of the past. CCDs have excellent properties in most metrics but have their own challenges for single photon counting applications. First, typical CCDs have a read noise of a few electrons, although recent modifications (EMCCDs) use an on-chip gain to amplify the signal above the read noise. Secondly, the signal is carried by charge that is transferred across the detector array. While CCDs for NASA missions are carefully fabricated to minimize defects, continuous bombardment from high energy radiation in space will damage the detector over the lifetime of the mission. This will degrade the charge transfer efficiency and in turn, reduce the single photon counting ability of the CCD. CMOS devices offer a different architecture that mitigates some of these problems. In CMOS image sensors, each pixel has its own charge to voltage converter and in-pixel amplifier mitigating issues found with charge transfer efficiency. Additional circuits that are critical to operation of the sensor can be incorporated on chip allowing for a parallel readout architecture that increases frame rate and can decrease read noise. This thesis is a collection of work for the characterization of a room temperature characterization, low-noise, single photon counting and photon number resolving CMOS detector. The work performed in this thesis will provide the framework for a technology development project funded by NASA Cosmic Origins (COR) program office. At the end of the two-year project, a megapixel CMOS focal plane array will be demonstrated to satisfy the stated needs of the LUVOIR and HabEx future astrophysics space mission concepts with a launch date near the 2040s."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: To understand the nature of light sources, one needs to know the statistical properties of emitted light and how the tools used to measure those properties reflect those statistics. This chapter will cover the vocabulary and notation necessary for understanding the characteristics of the sources and detectors covered in this book. After a brief review of the quantized electric field and relevant operators, we explore properties of single-photon sources, starting with relationships among state vectors, density matrices and photon number probabilities . Next we investigate properties of , the second-order coherence, and how it relates to . We present an in-depth study of the Hanbury Brown-Twiss interferometer, showing how it can be used to accurately measure in many—but not all—experimental situations. This is followed by a discussion of bunching, antibunching, Poissonian photon statistics, high-order coherences and indistinguishability. The second half of the chapter discusses characteristics of single-photon detectors, starting with the definition of detection efficiency used in this book. We review the POVM (Positive-Operator-Valued-Measure) operators, use them to illustrate the distinction between photon number-resolving (PNR) detectors and click/ no-click detectors, and explore some of the practical limitations of photon number-resolving and energy-resolving detectors. We next discuss the time response of detectors, including timing latency, rise time, timing jitter, dead time, reset time and recovery time. Finally, we cover the distinction between dark count rate and background count rate, and briefly discuss afterpulse probability, active area and operating temperature.

Available in PDF, EPUB and Kindle. Book excerpt: We discuss applying single-photon detectors to measurements with high accuracy. Two primary standard methods of detector calibration are reviewed: one based on a radiant power measurement (substitution method) and the other—on a simultaneous generation of photon pairs (correlation method). It is shown how to apply these methods to two types of detectors: with no photon number resolution (PNR) and with full PNR. In addition, an experimental comparison of the two calibration methods with non-PNR detectors is presented.

Download or read book Seeing Photons written by National Research Council and published by National Academies Press. This book was released on 2010-09-28 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense recently highlighted intelligence, surveillance, and reconnaissance (ISR) capabilities as a top priority for U.S. warfighters. Contributions provided by ISR assets in the operational theaters in Iraq and Afghanistan have been widely documented in press reporting. While the United States continues to increase investments in ISR capabilities, other nations not friendly to the United States will continue to seek countermeasures to U.S. capabilities. The Technology Warning Division of the Defense Intelligence Agency's (DIA) Defense Warning Office (DWO) has the critical responsibility, in collaborations with other components of the intelligence community (IC), for providing U.S. policymakers insight into technological developments that may impact future U.S. warfighting capabilities. To this end, the IC requested that the National Research Council (NRC) investigate and report on key visible and infrared detector technologies, with potential military utility, that are likely to be developed in the next 10-15 years. This study is the eighth in a series sponsored by the DWO and executed under the auspices of the NRC TIGER (Technology Insight-Gauge, Evaluate, and Review) Standing Committee.
Download or read book Astrophysical Lasers written by Vladilen Letokhov and published by OUP Oxford. This book was released on 2008-12-18 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in modern radio astronomy led to the discovery of space masers in the microwave range, and it became a powerful tool for studies of interstellar star-forming molecular clouds. Progress in observational astronomy, particularly with ground-based huge telescopes and the space-based Hubble Space Telescope, has led to recent discoveries of space lasers in the optical range. These operate in gas condensations in the vicinity of the mysterious star Eta Carinae (one of the most luminous and massive stars of our Galaxy). Both maser and laser effects, first demonstrated under laboratory conditions, have now been discovered to occur under natural conditions in space too. This book describes consistently the elements of laser science, astrophysical plasmas, modern astronomical observation techniques, and the fundamentals and properties of astrophysical lasers. A book with such an interdisciplinary scope has not been available to date. The book will also be useful for a wider audience interested in modern developments of the natural sciences and technology.

Download or read book Synchrotron Light Sources and Free Electron Lasers written by Eberhard J. Jaeschke and published by Springer. This book was released on 2016-05-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardly any other discovery of the nineteenth century did have such an impact on science and technology as Wilhelm Conrad Röntgen’s seminal find of the X-rays. X-ray tubes soon made their way as excellent instruments for numerous applications in medicine, biology, materials science and testing, chemistry and public security. Developing new radiation sources with higher brilliance and much extended spectral range resulted in stunning developments like the electron synchrotron and electron storage ring and the freeelectron laser. This handbook highlights these developments in fifty chapters. The reader is given not only an inside view of exciting science areas but also of design concepts for the most advanced light sources. The theory of synchrotron radiation and of the freeelectron laser, design examples and the technology basis are presented. The handbook presents advanced concepts like seeding and harmonic generation, the booming field of Terahertz radiation sources and upcoming brilliant light sources driven by laser-plasma accelerators. The applications of the most advanced light sources and the advent of nanobeams and fully coherent x-rays allow experiments from which scientists in the past could not even dream. Examples are the diffraction with nanometer resolution, imaging with a full 3D reconstruction of the object from a diffraction pattern, measuring the disorder in liquids with high spatial and temporal resolution. The 20th century was dedicated to the development and improvement of synchrotron light sources with an ever ongoing increase of brilliance. With ultrahigh brilliance sources, the 21st century will be the century of x-ray lasers and their applications. Thus, we are already close to the dream of condensed matter and biophysics: imaging single (macro)molecules and measuring their dynamics on the femtosecond timescale to produce movies with atomic resolution.
