Abstract
The present invention relates to a light scanner device () for measuring a range and an angular direction of a target object (), the device () comprising a pulsed source () adapted to transmit light pulses, a transmitter deflection means () adapted to reflect and sweep the transmitted light pulses in variable sweep directions across a sweep sector in a sweep plane (), a photodetection means () adapted to detect received light pulses that have been reflected in the sweep plane (), a receiver deflection means () adapted to reflect light pulses that have been reflected in the sweep plane () and to re-direct the reflected light pulses to the photodetection means (). The device comprises optical shielding means () adapted to optically shield transmitted light pulses on their trajectory from the pulse source () to the transmitter deflection means () and at least a portion of their trajectory extending from the transmitter deflection means () into the sweep sector from reflected light pulses on their trajectory between the photodetection means () and the receiver deflection means () and at least a portion of their trajectory extending in the sweep sector and ending on the receiver deflection means ().
