Abstract
The invention discloses an optical level compensator. The lower surface of a lower plane lens in the optical level compensator is bonded with an isosceles reflection prism, the upper surface of an upper plane lens is bonded with a right-angle prism, and a layer of refracting liquid is placed between the upper plane lens and the lower plane lens and is sealed by a shell; and emergent light obtained after incident light along the direction vertical to the lower plane lens passes through the optical level compensator is always parallel to the horizontal plane by utilizing the refraction and reflection matching relation among the refracting liquid, the right-angle prism and the isosceles reflection prism without relating to the placing pose of the optical level compensator. The optical level compensator can be widely used for automatically compensating parallel optical tubes, cameras and laser level gauges aiming at horizontal orientation.
Description
Technical field
The present invention relates to a kind of optics level compensator of reflection mode down, can realize that two-dimensional level compensates automatically, belong to field of optical measuring technologies.
Background technology
Obtaining of high precision vertical and high level of accuracy light need realize by compensation system, compensation method at present mainly contains hang spring (CN01224197.0), gravity hangs (CN200720192542.9), electron servo (CN200720093067), optics Anping methods such as (CN200820231704.X), the optics level compensator that the present invention relates to is the automatic compensation way of optics of liquids, method different from the past, in the employing planar lens directly and right-angle prism bonding, lower plane lens and isosceles reflecting prism are bonding, inject liquid between two planar lenss, the matching relationship that utilizes light to reflect therein and reflect, realized the two-dimension optical compensation that compensation of one dimension level and liquid are difficult to realize, utilize the prismatic reflection translation structure to avoid the overlapping of incident light in the single layer of liquid compensation light path and emergent light simultaneously, reduced incident angle, helped improving the precision and the compensation range of instrument liquid.
Summary of the invention
The object of the invention is to provide a kind of optics level compensator.This device can compensate the level optical system and put injustice or low frequency small angle inclination because of housing and disturb the level that causes to point to light departing from surface level, also can compensate the angle of oscillation displacement of horizontal emergent ray in surface level of tilting to cause by housing, and then realize the compensation of high-precision two-dimensional level.
Technical scheme of the present invention is: the invention provides a kind of optics level compensator, its special character be the optics level compensator by isosceles reflecting prism, lower plane lens, REFRACTIVE LIQUID, go up planar lens, right-angle prism and housing and form.
The lower surface bonds isosceles reflecting prism of above-mentioned lower plane lens, the bonding right-angle prism of the upper surface of last planar lens, the parallel placement of two planar lenss, between inject REFRACTIVE LIQUID, liquid natural surface and last planar lens are separated, by housing seal.
The ranges of indices of refraction of above-mentioned REFRACTIVE LIQUID greater than 1.49 smaller or equal to 1.5.
The bottom surface incident of the vertical isosceles reflecting prism of above-mentioned incident ray sees through REFRACTIVE LIQUID downwards and enters in the isosceles reflecting prism, and the back of turning back is reflected into horizontal emergent ray through right-angle prism again from the bottom-up outgoing of REFRACTIVE LIQUID.
The reversible light path of light path of the present invention is used.
Technical problem underlying and good effect thereof that the present invention can solve are:
1, realized the horizontal compensate function of single layer of liquid.
2, avoided the branch light energy losses.
3, the light channel structure compactness is beneficial to the volume miniaturization Design.
4, simple in structure, no multiplying power element is beneficial to the raising of precision.
5, can be applicable to be oriented in parallel light tube, video camera and the laser level of purpose, for system provides high-precision directed compensation with level.
6, reversible light path is used.
