Abstract

In order to meet the requirements of environmental stability of the existing 12m dynamic calibration system of laser interferometer, a novel air shower approach to maintain thermal stability for long-range laser interference optical path is proposed. The electric heating mode which can realize the rapid temperature control of air is organically combined with the heat exchange mode suitable for high-precision temperature control to complete the rapid and high-precision temperature control of air and realize the production of constant temperature air. By using simulation software to calculate and analyze the air shower temperature control effect of the system, the scheme is verified to be feasible. The experimental result shows that the developed high-precision thermal control system for long-range laser interference optical path can basically reach a thermal stability of ±0.023°C and fulfill the requirements of 12m dynamic calibration system of laser interferometer.
