Abstract: A laser riflescope includes a laser emitter, a laser receiver, an objective lens group (11) for collecting the visible light from the target to be measured, an eyepiece group (14) adapted for observation by the user of the distance information of the target and defining an optical axis with the objective lens group, a prism group (12) disposed between the objective lens group and the eyepiece group for light beam transmission, and a display element (13) for displaying the distance information of the target. The display element is an OLED having high transmittance to enhance the display brightness of the laser riflescope.

Abstract: A range finding digital camera (100) includes a main digital camera and a laser range finder (18) assembled to the main digital camera via a serial or a parallel connection interface. The main digital camera includes an image display (13) and a controller (15) for inputting commands to the laser range finder. The laser range finder includes an optical transmitter (181) for transmitting a transmission laser beam and an optical receiver (182) for receiving a reflection laser beam. The laser range finder is used for measuring the distance between an object and the range finding digital camera in accordance with the time-lag between the transmission time of the transmission laser beam and the receiving time of the reflection laser beam. The measuring result can be displayed on the image display and provided for the digital camera to focus or to calculate a practical dimension of the object.
