Compact Focal Plane Assembly for FIR Planetary Science

Completed Technology Project

Project Description

Compact Focal Plane Assembly for FIR Planetary Science

Building upon an FY11 IRAD in which we fabricated and characterized novel far-IR bandpass filters. With this IRAD we aim to integrate and test these filters with compact thermopile arrays, so as to build a low cost and low mass prototype thermal instrument for outer planet spectroscopy and/or radiometry.This task addresses a need for low mass and cost instruments on planetary science missions.


We will use a three-pronged approach: (1) Design and fabricate filter stacks; (2) integrate thermopiles with analog readout board into a cryogenic dewar; (3) characterize thermopiles with and without filter stacks using a far-infrared source.
