Digicon detector is same detector used in Hubble Space Telescope to discover the big universe because Digicon is single photon sensitive detector. This research was concern with a study of the detection process and signal amplification of the Digicon detector use in the laser radar receiver A silicon diode was used and the electron was accelerating from photocathode to solid state sensor. The gain from silicon material was computed by replacing the non-internal gain solid state sensor (silicon diode) by solid stat sensor which has an internal gain (avalanche diode). A computation and comparing has the energy loss by backscattering for silicon diode and avalanche diode were done in the present work. The energy loss by surface dead layer for silicon diode and avalanche diode was computed and compared. Also, computation and comparing the energy loss by thickness of surface dead layer for various thicknesses of surface dead layer and various incident electron energy angles for silicon diode and avalanche diode. Computation and comparing the pulse height for various thickness of surface dead layer and various incident electron energy angles for silicon diode and avalanche diode.
