Abstract: The actual value of a parameter from a laser range finder to a target is determined by adjusting the measured parameter by a measurement error. The error adjustment is based on the relationship between the intensity of the detected pulse and the expected parameter error. The laser range finder has a laser diode for emitting a laser pulse to a target to produce a reflected pulse, and a detector for receiving the reflected pulse. A measurement circuit is coupled to the detector for determining a measured parameter based on the reflected pulse. An integrator is coupled to the detector for determining the pulse area, and therefore, the intensity of the reflected pulse. A processor is coupled to the measurement circuit and the integrator for adjusting the measured parameter based on the pulse area of the reflected pulse, to provide the actual value of the parameter.
