A Multicolor Imaging Pyrometer

Physical Sciences Inc. (PSI) designed, constructed, and delivered a prototype passive imaging pyrometer capable of accurately measuring and controlling the temperature distribution across a specified surface. The device was originally designed, under a NASA SBIR contract (solicitation year 1985) monitored by Jet Propulsion Laboratory, for space application with a material processing acoustic levitation furnace, and thus the software allowed for registration of a surface that was allowed free motion within a defined range.
