Download or read book An FPGA based Hardware Accelerator for the Digital Image Correlation Engine written by Keaten Stokke and published by . This book was released on 2020 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this thesis was aimed at the development of a hardware accelerator for the Digital Image Correlation engine (DICe) and compare two methods of data access, USB and Ethernet. The original DICe software package was created by Sandia National Laboratories and is written in C++. The software runs on any typical workstation PC and performs image correlation on available frame data produced by a camera. When DICe is introduced to a high volume of frames, the correlation time is on the order of days. The time to process and analyze data with DICe becomes a concern when a high-speed camera, like the Phantom VEO 1310, is used which is capable of recording up to 10,000 Frames Per Second (FPS) [1]. To reduce this correlation time the DICe software package was ported over to Verilog, and a Xilinx UltraScale+ MPSoC ZCU104 FPGA was targeted for the design. FPGAs are used to implement the hardware accelerator due to their hardware-level speeds and reprogrammability. The ZCU104 board contains FPGA fabric on the Programmable Logic (PL) side that is used for the implementation of the ported DICe hardware design. On the Processing System (PS) side of the ZCU104, a quad-core ARM Cortex-A53 processor is available that runs the Ubuntu 18.04 LTS Linux-based kernel to provide the drivers for USB and Ethernet I/O, a standard file system that is accessed through a Command-Line Interface (CLI), and to run the program's control scripts that are written in C. This work compares the processing time of the DICe hardware accelerator when frame data is accessed via Ethernet-stream or local USB to showcase the fastest option when using DICe. Both methods of accessing frame data are necessary because data may be offloaded from the camera over Ethernet while it is still recording, or the frame data may be readily available in memory. By providing both a method to access frame data via USB and Ethernet, users have more flexibility when using the DICe hardware accelerator. The work presented in this thesis is significant because it is the first known hardware accelerator for the DICe software.

This book was released on 2023-07-13 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the rapid growth of computing and display technologies, digital holography (DH) has undergone significant advancement in the past two decades. Contemporary research works have enabled holography, a technology which is originally intended for displaying three-dimensional (3-D) images, to be deployed in numerous scientific, engineering, and bio-medical applications. Notably, digital holography has been incorporated into quite a number of contemporary applications, such as, but limited to holographic cryptography, optical metrology, remote sensing and inspection, and more recently, quantum computing. The success attained with DH so far does not limit its development to its current state-of-the-art, but rather research on holography keeps on expanding, with new ideas and methods keep coming up in a sustainable manner. This Research Topic aims to collect representative works from experts in the field, with the aim of providing an insight on the overall picture on digital holography, as well as reporting existing methodologies and emerging technologies that are likely to have strong impact on future research directions. Participating in the Research Topic, either as authors or readers, also facilitates establishing a platform for researchers to network, and to share their knowledge.

Download or read book Warped Time Stretch Photonic Hardware Accelerators for Imaging and Sensing written by Jacky Chak-kee Chan and published by . This book was released on 2018 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonic time stretch is a well-established real-time optical technology. Using dispersion, the spectral modulation of a broadband optical pulse is stretched to alleviate the bandwidth bottleneck present in the subsequent analog-to-digital conversion and digital processing. The recent warped time stretch generalizes this concept with tailored non-uniform dispersion profiles, reshaping the wideband optical information arbitrarily and in real-time. The approach provides a design pathway for translating a-priori knowledge of signal spectra into context-optimized data acquisition and processing. This has wide-ranging applicability, including optical pulse reshaping, feature extraction, network coding, data compression and optical phase retrieval. Here, we will analyze the effects of an arbitrary dispersion profile on wideband optical signals, and show how its proper design provides full-field control over critical parameters, e.g. time-bandwidth product, SNR etc. We first show some theoretical results, then apply the warped stretch framework to digital image compression. Finally, we demonstrate a physical implementation of large and reconfigurable dispersion.

Download or read book Digital Holographic Methods written by Stephan Stuerwald and published by Springer. This book was released on 2018-10-12 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents not only the simultaneous combination of optical methods based on holographic principles for marker-free imaging, real-time trapping, identification and tracking of micro objects, but also the application of substantial low coherent light sources and non-diffractive beams. It first provides an overview of digital holographic microscopy (DHM) and holographic optical tweezers as well as non-diffracting beam types for minimal-invasive, real-time and marker-free imaging as well as manipulation of micro and nano objects. It then investigates the design concepts for the optical layout of holographic optical tweezers (HOTs) and their optimization using optical simulations and experimental methods. In a further part, the book characterizes the corresponding system modules that allow the addition of HOTs to commercial microscopes with regard to stability and diffraction efficiency. Further, based on experiments and microfluidic applications, it demonstrates the functionality of the combined setup, and discusses several types of non-diffracting beams and their application in optical manipulation. The book shows that holographic optical tweezers, including several non-diffracting beam types like Mathieu beams, combined parabolic and Airy beams, not only open up the possibility of generating efficient multiple dynamic traps for micro and nano particles with forces in the pico and nano newton range, but also the opportunity to exert optical torque with special beams like Bessel beams, which can facilitate the movement and rotation of particles by generating microfluidic flows. The last part discusses the potential use of a slightly modified DHM-HOT-system to explore the functionality of direct laser writing based on a two photon absorption process in a negative photoresist with a continuous wave laser
