Abstract

Predictions of optical performance for spinning cryogenic infrared sensors that operate in changing thermal and structural dynamic environments requires performing analyses involving several technologies. Although the individual thermal, structural and optical analyses are not unique, the interfacing of these analyses is unique in the optical industry. This interfacing is an important problem in performing cost-effective system analyses that often require several design/analysis iterations. We have addressed this problem by writing interface codes in order to automate the data transfer among the separate analyses. Several design/analysis iterations were performed using the T/S/O process until the design met optical performance and other requirements across the wide temperature range. The design and trade-off process for the cryogenic spinning sensor (which contains materials with different coefficients of thermal expansion) is discussed. This paper shows how the T/S/O process has been used to design a sensor that is nearly athermal across a wide temperature range.
