| Abstract: | The property that the light intensity of the returned image from auto-collimating reticule varies with the reflectivity is utilized. The corresponding photoelectric receiver is added in the auto-collimator. The flat mirror which reflectivity is known is set to be standard so as to process comparative measurement. The measurement of whole aperture's reflectivity for perpendicular incidence and reflection is achieved to adapt to corresponding active condition and various object. |
