Abstract
An optical apparatus for ranging and communication in free space comprises a rangefinder comprising a device for transmitting an optical signal to a target and a device for receiving the signals backscattered by the target. A system for optical communication in free space comprises a device for transmitting an optical signal to a remote optical receiving device. The transmitting device of the rangefinder and transmitting device of the communication system is a transmitting device common to the rangefinder and communication system and transmitting pulses of peak power greater than 50 W and shape factor less than 0.01 or a modulated continuous signal of peak power less than 10 W and shape factor equal to approximately 0.5 and the apparatus comprises a supervisor controlling the common transmitting device according to two modes, the pulse mode to perform the ranging function, or the modulated continuous mode to perform the optical communication function.
