ABSTRACT:
A thermal imaging system (10) contains a focal plane array (30) including a plurality of thermal sensors (32) mounted on a substrate (62). Each thermal sensor (32) includes a film layer (34) of infrared sensitive material which is both electronically and thermally isolated from the associated integrated circuit substrate (62). An image may be formed on the film layer (34) in response to infrared radiation from a scene (12). Electromagnetic radiation (22) from a source (visible light or near infrared) (20) is used to reproduce or transfer the image from the thermal sensors (32) onto the first surface (68) of the substrate (62). A thermoelectric cooler/heater (66) may be provided to optimally adjust the temperature of the substrate (62) to improve overall image quality.
