Embodiment Construction

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as there is no conflict with each other.

[0029] like Figure 1 to Figure 4 As shown, a modeling method for an optical system of a camcorder based on image-side scanning includes the following steps:

[0030] 1) In a working interface of ZEMAX, call out the focusing lens group 1, the zoom lens group 2, the compensation lens group 3, the diaphragm 8, the collimating lens group 4, and the rear fixed lens group 6 from the component library of...

Abstract

The invention discloses a modeling method for an optical system of a camcorder based on image-side scanning, comprising the following steps: 1) calling out a focusing lens group, a variable magnification lens group, a compensation lens group, Diaphragm, collimating lens group, rear fixed lens group and CMOS imaging assembly, optimize the aberration of each lens group; 2) make the collimating lens have a collimating effect; 3) replace the rear fixed lens group with an ideal lens, and the lens 4) Re-optimize the rear fixed lens group separately in another working interface; 5) Combine and optimize the rear fixed lens group with other lens groups. This modeling method uses ZEMAX modeling, which can conduct targeted analysis and optimization for the selection of optical components in the optical system, so as to obtain a camcorder optical system with excellent imaging quality, the modeling is accurate and reliable, and the optical system is improved. efficient utilization and high functional density.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic devices, and more particularly, relates to a modeling method of 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 vicinity of a large field of view, and can also meet the tracking of low-speed and long-distance flying objects in a small field of view. It is used in aircraft. During the flight of the aircraft, it is also necessary to perform reverse scanning reconnaissance photography or key target photography functions in the designated area during the flight. Therefore, there are high requirements for the image stability recorded by the optical system of the camcorder. [0003] When the camcorder is used in the airborne optoelectronic pod of the aircraft, it is mainly used to record important target events during flight training and exer...
