58×62 InSb focal plane array for infrared astronomy.
Abstract
Santa Barbara Research Center has developed a 58 x 62 staring mosaic focal plane array (FPA) consisting of an indium antimonide detector array hybridized to a silicon direct readout (DRO) multiplexer for use in IR astronomy. The detectors are sensitive to radiation from 1 to 5 microns. Each detector in the array is connected to the DRO via an indium bump contact and has its own high-impedance, low-capacitance buffer amplifier. The requirements of infrared astronomy include low dark-current and readout noise for near-BLIP performance and full-frame readout times from 32 ms to more than 20s. Both modeling and measurements of the FPA performance are presented. Results include responsivity, noise, NEP, linearity, and dark current.
