PURPOSE:To obtain a small type high capacity optical system of a laser radar, by integrating a transmitting telescope and a receiving telescope while performing the branching of the light transmitting path and the light receiving path thereof by a rotary mirror. CONSTITUTION:Transmitting laser beam 28 emitted from a laser oscillator 24 is reflected from a rotary mirror 22 to enter the optical axis of a telescope 21 and projected toward a target 30. It is necessary to project the transmitting laser beam 28 so as to always coincide the same with the optical axis of the telescope 21. Therefore, a trigger signal generator 27 imparts indication to the laser oscillator 24 on the basis of the output signal from the rotary angle detector 26 of the rotary mirror 22 so as to oscillate the laser oscillator 24 at the definite angle of the rotary mirror 22. |
