Paper Abstract

The Thermal Light Valve™ (TLV) is a diffractive thin film spatial light modulator that provides high response to long-wavelength infrared radiation. In this paper we describe the rationale for optical-readout thermal imaging arrays, and some of the challenges faced by past devices. We then describe the TLV device, its solid state structure, readout system configuration, and performance parameters. We show how the TLV overcomes key performance issues faced by previous optical-readout arrays to achieve a modeled system performance of 16mK NETD. In addition we describe the TLV's advantages from the point of view of manufacturing tolerances and wide ambient temperature operating ranges resulting in a TLV chip yield in excess of 95% - a critical cost advantage of RedShift Systems' OpTIC™ optical thermal imaging cores.
