Abstract

Small pixel pitch sensors offer opportunities for imaging system SWaP reduction that open up a variety of SWaP-constrained applications that were not previously feasible. Furthermore, small pixel digital sensors provide advantages in the form of additional SWaP reduction, noise immunity, and simplified interfacing requirements. With these motivations in mind, Attollo Engineering has developed a 640x512, 5μm pixel pitch, high operating temperature MWIR sensor based on III V compound semiconductor detector materials. We have adapted our 5μm pixel pitch SWIR processes for MWIR detector materials and have been able to achieve 99.5+% operability MWIR FPAs with BLIP performance operating at 130K. Additionally, we have developed a compact camera core with an integrated cooler and full featured camera electronics. The global shutter camera is capable of frame rates of up to 220 Hz or smaller windows in excess of 1 kHz and integration times as low as 100 nanoseconds. Attollo will discuss characteristics of this sensor and other related technologies.
