Abstract

The invention discloses an open long-optical path multiple reflecting pool system for eliminating turbulence effect, which comprises a reflecting pool consisting of a main lens and auxiliary lens. A laser is arranged outside the reflecting pool; a half transparent and half reflecting lens is arranged between the laser and the main lens; a photoelectric detector is arranged on one side of the reflecting pool; and the outer lens surface at the other end of the main lens is provided with a corner cube mirror. The open long-optical path multiple reflecting pool system eliminates the turbulence effect in the long-optical path multiple reflecting pool so as to reduce the disturbance of the turbulence effect in an optical path on the light beams, improve the stability of emergent light beams of the multiple reflecting pool and increase the total optical path of the long-optical path multiple reflecting pool.

Description

technical field [0001] The invention relates to the field of optical instruments, in particular to a reflective pool, in particular to an open long optical path multiple reflective pool system that eliminates turbulence effects. Background technique [0002] In an open multiple reflection pool, the effect of atmospheric turbulence can disturb the optical path. The specific situation is: 1. When the atmospheric turbulence effect increases, the optical path in the multiple reflection pool is affected by the disturbance of the turbulence effect, causing the optical path to shift; 2. After the distance between the primary mirror and the secondary mirror of the multiple reflection pool increases, there is a slight The effect of atmospheric turbulence will cause the optical path in the multiple reflection pool to shift. Contents of the invention [0003] The object of the present invention is to provide an open long optical path multiple reflection pool system that eliminates t...
