Abstract

The invention discloses a modeling method of a photographing and recording all-in-one machine optical system based on image space scanning. The method comprises the following steps: 1) calling out a focusing lens group, a zoom lens group, a compensation lens group, a diaphragm, a collimating lens group, a rear fixed lens group and a CMOS imaging assembly from an element library of ZEMAX, and carrying out aberration optimization on each lens group; 2) enabling the collimating lens to have a collimating effect; 3) adopting an ideal lens to replace the rear fixed lens group, and carrying out aberration optimization on the lens group to make the imaging quality excellent; 4) independently optimizing the rear fixed lens group again in the other working interface; and 5) combining and optimizingthe rear fixed lens group and other lens groups. According to the modeling method, the ZEMAX is used for modeling, and selection of optical elements in the optical system can be analyzed and optimized in a targeted mode, so the photographing and recording all-in-one machine optical system with the excellent imaging quality can be obtained, modeling is accurate and reliable, and the effective utilization rate and the high functional density of the optical system are improved.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic equipment, and more specifically relates to a modeling method for an optical system of a camcorder. Background technique [0002] The camcorder is widely used in the observation and tracking of objects, which can meet the search and capture of fast flying objects in the large field of view, and can also meet the tracking of medium and low speed long-distance flying objects in a small field of view. It is used in aircraft At the same time, during the flight of the aircraft, it is also necessary to perform reverse scanning reconnaissance and photography of designated areas or key target photography functions. Therefore, the image stability of the optical system of the camcorder has high requirements. [0003] When the camcorder is used in the airborne photoelectric pod of the aircraft, it is mainly used for recording important target events during flight training and exercises. Due to the mo...
