Research on Focal Length Measurement Scheme of Self-Collimating Optical Instrument Based on Double Grating

In this paper, we propose a scheme for measuring the focal length of a collimating optical instrument. First, a mathematical model for measuring the focal length of a collimator with double gratings is derived based on the moiré fringe formula and the principles of geometric optics. Mathematical sim...
