Document Type and Number:
Japanese Patent JP6577465
Kind Code:
B2
Abstract:
The invention relates to a laser detection and ranging device (100) for detecting an object under a water surface, the laser detection and ranging device (100) comprising a laser transmitter (101) being configured to modulate a laser beam by a binary pseudo-random coding sequence to obtain a modulated laser beam, and to transmit the modulated laser beam towards the water surface, a laser detector (103) for detecting a reflected laser beam, the reflected laser beam forming a reflected version of the transmitted laser beam, and a processor (105) for detecting the object under the water surface upon the basis of the reflected laser beam.
