Abstract
A technique for a pulse/phase based laser rangefinding instrument utilizing a single photodiode in conjunction with separate pulse and phase receiver circuits. The photodiode receives phase and pulse ranging signals and a capacitor coupled to the photodiode and is operative to provide current through the photodiode to a transimpedance amplifier in a pulse mode of operation and from the photodiode through a tuned circuit to a narrow band amplifier in a phase mode of operation.
