This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A fast spectrometer capable of operating at 27.8 KHz is designed and calibrated to work in the wavelength range of 700-900 nm, to perform Fourier Domain Optical Coherence Tomography (FD-OCT). The OCT system is based on fiber-based Michelson's interferometer set up utilizing the spectrometer at the detector end. In FDOCT system no reference scanning is necessary and hence images can be acquired at a much faster rate without any penalty to signal-to-noise ratio (SNR). A broadband Ti-sapphire source is used as input to the interferometer. Data at the rate of 60 MHz is acquired from the spectrometer using a frame grabber and a DAQ card is used for synchronization and scanning of the galvanometers in the sample path. Lab-VIEW(TM) is used as interface for data collection and processing. The theoretical resolution of the spectrometer is calculated to be 0.11 nm resulting in the measurable depth range of 1.54 mm. Signal-to-noise for the system was experimentally found to be 52.05 dB. Video-rate OCT image acquisition capability of the FD-OCT system is demonstrated.

Available in PDF, EPUB and Kindle. Book excerpt: Many applications today require the Fourier-transform (FT) spectrometer to perform close to its limitations, such as taking many quantitative measurements in the visible and in the near infrared wavelength regions. In such cases, the instrument should not be considered as a perfect "black box." Knowing where the limitations of performance arise and which components must be improved are crucial to obtaining repeatable and accurate results. One of the objectives of this book is to help the user identify the instrument's bottleneck.
