LASER RANGING DEVICE AND INSTALLATION METHOD FOR PHOTOSENSITIVE CHIP THEREOF

WIPO Patent Application WO/2017/202384

A1

Provided are a laser ranging device and an installation method for a photosensitive chip thereof. The laser ranging device comprises a line laser transmitter (200) disposed at a fixed base (100) and an image sensor. The image sensor comprises a lens (300) and a circuit board (400). A photosensitive chip assembly (500) is securely disposed at the circuit board (400). The photosensitive chip assembly (500) is formed by joining two identical photosensitive sub-chips (501) in a longitudinal direction. A fitting relationship between the lens (300) and the photosensitive sub-chips (501) is as follows: the lens (300) fits an image sensor measuring 1/n inches, and the photosensitive chip assembly (500) is formed correspondingly by joining two photosensitive sub-chips (501) measuring 1/2n inches. A photosensitive surface between two longitudinal sides of the photosensitive chip assembly (500) covers points B and A at which lines, extending from respective lines connecting preset farthest and closest measurement points with the center, O, of the lens (300), intersect with a plane in which the photosensitive chip assembly (500) is located, such that a ranging scope of the laser ranging device can meet needs of a user.
