PROBLEM TO BE SOLVED: To provide an optical scanner suitable for use in an application such as external application, and capable of ensuring a proper operation over a long use period. SOLUTION: The optical scanner 10 for measuring a range and an angular direction of a target object 56 comprises a pulse source 12 adapted to transmit light pulses, a transmitter deflection means 20 adapted to reflect and sweep the transmitted light pulses in variable sweep directions across a sweep sector in a sweep plane 15, a photodetection means 42 adapted to detect received light pulses that have been reflected in the sweep plane 15, a receiver deflection means 24 adapted to reflect light pulses that have been reflected in the sweep plane 15 and to re-direct the reflected light pulses to the photodetection means 42, and an optical shielding means 32.
