Title: (EN) Laser distance measuring and aiming coaxial optical system
(ZH) 一种激光测距与瞄准共轴光系统
Abstract: front page image
(EN) 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.
