Abstract

The invention discloses a continuous zoom television optical axis consistency detection device under high and low temperature conditions. The continuous zoom television optical axis consistency detection device comprises a high and low temperature box and a parallel light emitting mechanism, the high-low temperature box comprises a box body, a buffer piece and a temperature adjusting piece, the box body is provided with a closed containing cavity, and the containing cavity is used for containing a continuous zoom television; and the parallel light emitting mechanism is located outside the containing cavity and used for emitting parallel light with cross division to the input end of the continuous zoom television. The technical scheme provided by the invention has the advantages that the to-be-detected continuous zoom television is put into the high-low temperature box, a high-temperature or low-temperature environment is achieved in the high-low temperature box through the temperature adjusting piece, and the parallel light with cross division is emitted into the input end of the continuous zoom television through the parallel light emitting mechanism; therefore, the consistency of the optical axis of the continuous zoom television under high and low temperature conditions can be detected, and meanwhile, the temperature adjusting piece is connected to the box body through the buffer piece, so that the influence of vibration of the temperature adjusting piece on a test is reduced when the temperature adjusting piece works.

Description

technical field [0001] The invention relates to the technical field of optical adjustment, in particular to a device for detecting the consistency of the optical axis of a continuous zoom TV under high and low temperature conditions. Background technique [0002] As an important part of the photoelectric search and tracking system, continuous zoom TV is widely used in the military field, especially in reconnaissance and fire control systems, due to its small size, light weight, continuous zoom, long range, clear imaging, and fog penetration. been more and more applied. The continuous zoom TV can search for the target, realize the observation from far to near, and realize the stable tracking of the image. These advantages are based on the condition that the optical axis consistency in the continuous zoom TV is very good, therefore, the optical axis consistency is the guarantee for the continuous zoom TV to realize its function. Under normal temperature conditions, the optic...
