| Abstract: | Aiming at deficiency of line displacement sensors based on varied-line-space grating, a new type of sensor test system is presented. Independently developed broadband LED light source, which has advantages of small size and high efficiency is an ideal light source for optical displacement sensors. Varied-line-space blazed grating and sleeve style operation mechanism are applied in sensor. The signal is processed by color sensitive demodulator and DSP, and prototype of the sensing system is fabricated and tested, the test precision in accordance with demand of flight control system, and the dynamic performance is improved, miniaturization and engineering are realized. |
