A temperature-controlled complementary metal oxide semiconductor camera

In recent years, complementary metal oxide semiconductor (CMOS) imaging sensors have been replacing charge-coupled device (CCD) imagers in consumer and industrial markets. Their Alow cost and high peripheral integration on chip gives new opportunities to those who have not adopted CCD technology due to cost or technical concerns. This paper describes the design of a prototype CMOS camera for use in spectral experiments with noise reduction Atechniques to improve image quality. We use a Peltier device to cool the sensor, a Asynchronous dynamic random access memory (SDRAM) frame buffer for storage and a universal Aserial bus (USB) interface to transfer the data at a high speed.
