Paper Abstract

Gallium Nitride (GaN) UV detectors have become one of the most important UV detectors for much more compact, more robust, higher quantum efficiency and good stability in higher temperature environment than the traditional detectors. We can evaluate the quality of the detectors by detectivity, responsivity, Signal-to-Noise (the detector with read-out circuit), etc. Although these methods can analyze performance quantificationally, they are partial and indirect. The demo imaging system described in this paper provided a simple and more direct way as an assistant method. We can easily assess the performance of the detectors in actual application by the images obtained by the imaging systems. The system is mainly designed for 64x1 linear UV detectors (the band is 330nm ~ 365nm). It is composed of a precise scanner platform to provide 1-D wide field scan (it can be extended to 2-D if needed), UV telephoto optical system, signal transfers and processing system and the software. The detail design of these components is introduced. The images obtained by the system are also given at the end of the paper.
