Abstract

The invention provides an optical axis stabilizing device in light-path transmission among optical platforms and a control method. The device comprises a platform A and a platform B; the platform A is provided with a laser A, a reflection mirror, a pupil detector, a light splitter A and a fast reflection mirror A; the platform B is provided with a laser B, a fast reflection mirror B and a light splitter B; the center of the fast reflection mirror B is provided with a hole, and an optical axis detector is installed in the hole; a light beam emitted by the laser A is reflected to the optical axis detector sequentially through the reflection mirror, the light splitter A, the fast reflection mirror A, the fast reflection mirror B and the light splitter B; and a light beam emitted by the laser B reaches the pupil detector through the light splitter A after being reflected by the fast reflection mirror A. Due to the adoption of the stabilizing device and the control method, the joggling of an optical axis can be controlled when the light beam is transmitted among different platforms, so that an effect for stabilizing the optical axis in the transmission process can be realized.

Description

technical field [0001] The present invention relates to the field of optical axis stabilization in optical path debugging of optical systems, especially an optical axis stabilization device and control method in optical path transmission between optical platforms. Background technique [0002] In the prior art, it is known that in the optical path debugging of the optical system, it is usually encountered that one optical platform cannot completely place optical devices, and it is necessary to build an optical path on another optical platform to complete the placement of the optical system . For optical systems that do not require high technical indicators, the two optical tables adopt a hard support method, and the height of the two platforms can be adjusted to the same height. For optical systems that require high technical indicators, both optical tables need to have vibration reduction or Vibration isolation measures prevent the high-frequency vibration of the optical t...
