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.
