Abstract
The invention relates to a laser distance measuring and aiming coaxial optical system. An objective, a Pechan prism combination, a distance measurement cubic prism, a projection cubic prism and an eyepiece group of the laser distance measuring and aiming coaxial optical system are sequentially distributed along an optical axis; the objective is used for imaging of an optical system and receiving of a laser signal, i.e. the objective is used for imaging an image of a target on a reticle by the Pechan prism combination and the distance measurement cubic prism behind the target and simultaneously converging the energy of laser onto a photoelectric detector; Pechan prisms are used for transferring of an aiming lens system, so that an integral aiming lens is an erecting system; the distance measurement cubic prism is used for implementing light splitting of the laser and white light, splitting the laser onto the photoelectric detector, implementing the distance measurement function of the product and simultaneously transferring the white light to the reticle to implement the target imaging; the reticle is positioned on a focal plane of the system, is provided with aiming scales and is used for the aiming of the target; the projection cubic prism is used for implementing the projection on an OLED (organic light emitting diode) display screen; and the OLED display screen and the reticle are conjugate areas related to an objective system, so that the objective can be used for simultaneously observing both the clear images of the target and the OLED display screen.
Description
Technical field
The present invention relates to a kind of laser range finder, particularly a kind of laser ranging and the coaxial photosystem of aiming.
Background technology
Taking aim in the mirror with the fire control of laser ranging, for realizing range finding, aiming and the function that shows, optical design adopts Porro prism to carry out image rotation and light splitting more, the projection objective group shows, its complex structure, size is large, seems heavy so that integral body is taken aim at mirror system, and the part processing cost is high, has limited the use value of product.
Summary of the invention
The purpose of this invention is to provide a kind of laser ranging and the coaxial photosystem of aiming, it is the laser ranging that a kind of topology layout is compact, size is little, the part processing cost is low and the optimization device that aims at coaxial system.
The object of the present invention is achieved like this, and a kind of laser ranging and the coaxial photosystem of aiming is characterized in that: comprising: object lens, benhain prism group, range finding block prism, projection block prism and eyepiece group; Object lens, benhain prism group, range finding block prism, projection block prism and eyepiece group distribute along optical axis successively; Object lens are used for the reception of optical system imaging and laser signal, the picture of target benhain prism and the range finding block prism by the back is imaged on the graticule, simultaneously with the energy centralization of laser on photodetector; Benhain prism is used for taking aim at the image rotation of mirror system, and making integral body take aim at mirror is erecting system; The range finding block prism is realized the light splitting of laser and white light, and laser is assigned on the photodetector, realizes the distance measurement function of product, simultaneously white light is sent to the imaging of graticule realize target; Graticule is positioned on the focal plane of system, with line of sight, is used for the aiming of target; The projection block prism is realized the projection to the OLED display screen, and OLED display screen and graticule are the conjugate plane about eyepiece system, the eyepiece that can make while object observing and OLED display screen all for clearly as; The eyepiece group is used for observing and aiming.
Described range finding block prism has identical optical texture with the projection block prism.
Described range finding block prism one side has photodetector, and projection block prism one side has the OLED display screen, and photodetector and OLED display screen are distributed in the optical axis both sides.
Between range finding block prism and projection block prism, graticule is arranged.
Advantage of the present invention: realize in the function of taking aim at range finding in the mirror, aiming with the fire control of laser ranging and showing, not only simplified traditional optical system, simultaneity factor is designed to coaxial system, integral layout is compact, very large compression take aim at physical dimension and the weight of mirror so that product has more use value and market competition advantage.Whole light path design is coaxial system, compact conformation, very large compression take aim at physical dimension and the weight of mirror so that product has more use value and market competition advantage.
