Abstract: A laser receiver comprising a sensor; a first amplifier operatively connected to the sensor comprising a first gate, a first source and a first drain; a first subcircuit operatively connected between the first drain and the first gate comprising a first resistor, a first inductor and a decoupling capacitor configured to allow the first amplifier bias to be established by the at least one first biasing resistor; the impedance of the first gate being sufficient such that only a small proportion of the current from the sensor passes into the first gate; an inductor connecting the first gate to the at least one biasing resistor with high impedance at the receiver operating frequency; a second amplifier comprising a second gate operatively connected to the first drain; and an output configured to be operatively connected to a processing unit and a display unit configured to displaying output and method thereof.

Abstract: A system comprising a laser for transmitting a beam of light towards a target area; a controller for controlling the output of the laser; a receiver for collecting reflected pulses of light reflected from the target area, the receiver comprising a plurality of receive elements, each of the receive elements having a different field of view; a combiner for combining the outputs of the receive elements into one composite signal of the target area; an interface circuitry for converting the composite signal into an image; display unit displaying output from interface circuitry.
