Abstract
The invention relates to a vertical horizontal compensator and belongs to the field of optical measurement. Based on a liquid optical compensation principle, the device can be used for realizing horizontal and vertical compensation. An upper plane lens of the device is glued with an isosceles reflection prism, a lower plane lens is glued with a penta prism and a beam-splitting prism, and optical liquid is injected between the upper plane lens and the lower plane lens. Through a matching relation of the optical liquid and an upper reflection prism and a lower reflection prism, the automatic optical compensation of a horizontal one-dimensional and vertical two-dimensional light beam or a horizontal two-dimensional and vertical one-dimensional light beam is realized. The vertical horizontal compensator can be widely applied to the automatic optical compensation of vertical and horizontal orientation of a collimator, a camera system and a laser alignment system.

The reflecting surface (2) of above-mentioned isosceles reflecting prism (1) and reflecting surface (3) all are 30 ° with the lower surface angle of last planar lens (4), and utilize the lower surface of going up planar lens (4) to carry out total reflection.
When the reflecting surface (2) of above-mentioned isosceles reflecting prism (1) and reflecting surface (3) all are plane reflection, can realize the compensation of horizontal direction one dimension and the compensation of vertical two dimension simultaneously.
The reflecting surface (2) of above-mentioned isosceles reflecting prism (1) and reflecting surface (3) both one of when being the ridge reflecting surface, can realize the two-dimensional level compensation, eliminate the angle of oscillation displacement of emergent ray in surface level that housing rotates, tilts to cause around horizontal emergent ray (13) direction, realize the one dimension VCP of vertical simultaneously.
Above-mentioned vertical-horizontal compensator, vertical lower plane lens (7) incident of incident ray (8), upwards transmission optics liquid (5) enters in the isosceles reflecting prism (1), light reflected (14) sees through optics liquid (5) again, be reflected into horizontal light (13) twice through pentaprism (10), directly be transmitted as vertical light (11) through pentaprism (10) and Amici prism (12).
Technical problem underlying and good effect thereof that the present invention can solve are:
1, can realize horizontal one dimension, vertical two dimension compensation or horizontal two-dimension, the compensation of vertical one dimension simultaneously;
2, solve single layer of liquid compensation system in the past and need strengthen incident angle to liquid, avoided the overlapping problem of incident light and emergent light, be conducive to enlarge compensation range, improved compensation precision;
3, can use on the backlight road;
4, can be widely used in parallel light tube, the automated optical compensation that the vertical of camera system and laser collimation system and level are pointed to.
