and it involves many subjects.Incremental optical grating encoder is used in the position sensor for the laser radar sannning system
its working characteristics is studied and measurement circuit is designed.The linearity and repeat precision of the incremental optical grating encoder are tested and calibrated.The experimental results show that the linearity of incremental optical grating encoder reaches to 99.97 % and repetitive precision can reach to 18″
it can offer precise position information for the laser radar system.
