Title: A VLSI optical detector array employing heterodyne detection
Author: Soni, Tejvansh Singh
Abstract: The integration of image sensors with circuitry for driving the image sensor and performing on -chip signal processing is becoming increasingly popular for a multitude of signal processing applications . A high degree of on -chip signal processing helps enable miniaturization of instrument systems and simplify system interfaces . In this work , the design of a powerful and versatile VLSI optical sensor array , with on -chip circuitry to perform temporal electronic heterodyne detection on a pixel -bypixel basis is presented . Heterodyne detection techniques significantly enhance the dynamic range and signal to noise ratio , as compared to base -band detectors . The unavailability of heterodyne detector arrays has been a bottleneck in many imageprocessing systems , restricting the use of heterodyne detection techniques to scanning based systems , or systems having a single temporal output , such as acousto -optic space integrating correlators and convolvers . The need for heterodyne detector arrays in acousto -optics has been emphasized by prominent researchers in the field .
