Abstract
A laser radar system includes: a scanner for transmitting a pulse toward a target while two-dimensionally scanning a transmitting beam, and outputting scan angle information; a lens of the receiver for receiving received light; a high aspect photo detector array for converting the received light into a received signal; a transimpedance amplifier array for amplifying the received signal; an adder circuit for adding the received signal from each element of the transimpedance amplifier array; a distance detecting circuit for measuring a light round-trip time to the target of an output signal from the adder circuit; and a signal processing unit for causing the scanner to perform a two-dimensional scanning operation in association with the scan angle information, to determine distances to multiple points on the target based on the light round-trip time and a speed of light and measure a three-dimensional shape of the target.
