Abstract
A laser detection and ranging (LADAR) system is provided for generating a three-dimensional image of an object. The LADAR system includes a laser source configured to project a laser beam onto the object, and a photodiode detector array configured to detect a reflection of the laser beam projected onto the object. The photodiode detector array includes a back interface, a front interface positioned opposite the back interface, and a passivation region disposed between the back interface and the front interface. The back interface includes at least one window, and the front interface includes at least one active region oriented to detect a photon associated with the reflection. The at least one active region includes an absorber and a multiplier. The filter is configured to have a bandgap between an absorber bandgap and a multiplier bandgap.
