A Temperature Controlled CMOS Camera

In recent years CMOS imaging sensors have been replacing CCD imagers in consumer and industrial markets. Their low 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 techniques to improve image quality. We use a Peltier device to cool the sensor, an SDRAM frame buffer for storage and a USB interface to transfer the data at high speed.
