Abstract
This paper describes a precision subminiature three-axis translation stage used in the GOES Sounder to provide positional adjustment of twelve cooled infrared detectors. Four separate translation stages and detectors are packaged into a detector mechanism which has an overall size of 0.850 X 1.230 X 0.600 inches. Each translation stage is capable of +0.015 inch motion in the X and Y axes and +0.050/-0.025 inch motion in the Z axis with a sensitivity of 0.0002 inches. The function of the detector translation stage allows real time detector signal peaking during Sounder alignment. The translation stage operates in a cryogenic environment under a 10-6 torr vacuum.
