Abstract

Thermo-mechanical detector arrays in the 160 × 120 array format are designed, fabricated, and tested. Detectors are composed of SiN_x and TiN as absorbing layer, Al to form bimaterial legs, and integrated diffraction grating interferometer underneath each detector. The detector array is a passive component and the optical readout is performed remotely with a laser and CCD camera. All noise sources are considered in making a detailed noise equivalent temperature difference (NETD) estimation, which revealed <30 mK NETD is achievable using >12-bit CCD camera for the readout.
