Abstract

Abstract

It is a common design method to reduce the volume and mass of aerial remote sensors by using the plane mirror to replace the light path. However, the introduction of a plane mirror puts forward stricter requirements for the alignment of the aerial remote sensor. We propose an alignment method for the plane mirror system of an aerial remote sensor. The mathematical model of the theodolite measurement is established by the coordinate transformation method, and the corresponding relationship between the angular deviation (pitch deviation and azimuth deviation) of the single plane mirror assembly and plane mirror system and the measured value of the theodolite is deduced. Then a method of measuring and adjusting the angle deviation of the plane mirror system with theodolite is proposed. Finally, the pitch angle deviation and azimuth angle deviation between the lens optical axis and the normal of the focal plane mounting surface meet the index requirements of being no more than 2′. More than 10 sets of aerial remote sensor plane mirror systems have been aligned using this method, which is both convenient and efficient. At the same time, this method can provide a solution for the angle calibration and alignment of the plane mirror in various optical instruments.
