摘要
Abstract
In order to improve focusing effect of the crystalline lens on the laser beam in a temperature sensor dynamic calibration system, a 90° off-axis parabolic mirror was used instead of the crystalline lens. The influence of the misalignment angle of the 90° off-axis parabolic mirror on the focused laser spot was studied according to geometrical optics. Utilizing the improved system, the CHAL-010-type thermocouple's time constant at step temperature around 242℃ was tested and the dynamic calibration experiment was carried out. The results show that the new system reconstructed with the 90℃ off-axis parabolic mirror can fulfill the dynamic calibration of temperature sensors.关键词
