Abstract

Optimizing the performance of a telescope requires the ability to accurately measure and monitor the spatial variation of temperature in critical components. Surfaces near a telescope may warm or chill ambient air and cause image degradation. It is desirable to monitor the temperature of such systems. The design, fabrication and testing of a reliable, low-cost, multiplexed temperature measurement system with a resolution and stability approaching 0.01 degree(s)C is described. This system, with 176 temperature sensors, will be used to monitor the performance of a 3.5 m borosilicate mirror ventilation system. It is applicable to a broad range of telescope and telescope enclosure temperature measurement problems.
