The principle of optical signal reception of laser receiver is analyzed. The controller is designed by using current mirror technology. The design of CMI unit and cooperative double sampling circuit are introduced to reduce the receiver energy consumption. Experimental results show that in the normal temperature range, laser receiver energy consumption decreased significantly.
