Abstract: An optical range finder measuring distance to a target and capturing the image of the target simultaneously is provided. The optical range finder includes an emitting system emitting a pulse toward the target and a receiving system receiving the pulse reflected from the target, to calculate the distance there between. The emitting system or the receiving system includes a beam splitter for separating the visible beam of the target from the pulse, and the visible beam of the target is received by an image sensor. Thus, the optical range finder measures the distance and captures the image of the target. Moreover, the optical range finder further includes a display showing the captured image and distance data.

Abstract: An exposure adjustment method for night-vision camera includes the following steps. A first image and a second image are shot with an infrared light source of different intensity; the shot first image and second image are divided into a plurality of image blocks, in which positions of the image blocks in the first image are respectively corresponding to those in the second image; a light reflectivity of the image blocks of the first image is compared with a light reflectivity of the image blocks of the second image, and object distances of image objects are determined; the image object having greater object distance obtains a lower light measuring weight, and the image object having smaller object distance obtains a higher light measuring weight; and an exposure parameter of image images is adjusted according to the image weights of the two images and light measuring weights of the blocks.

Abstract: A lens system includes, in sequence from an object side to an image side, a first lens group having negative refractive power; a second lens group having positive refractive power, which includes a composite lens with aspheric resin layers formed on object side and image side thereof, respectively; and a third lens group having positive refractive power. In zooming, the first lens group remains stationary and when performing from the wide-angle end to the telephoto end, the second lens group moves away from the image plane, while the third lens group moves toward the image plane, whereby the distance between the first and second lens groups is decreased, while the distance between the second and third lens groups is increased.
