<p>PURPOSE:To improve the utilizing efficiency of light by providing recessed optical reflection plates at a pitch of picture elements to a side opposite to an optical incident face. CONSTITUTION:Recessed reflection mirror plates 3 reflecting a light transmitted through a dead band toward a Schottky diode 1a in which the light is collected are arranged at a pitch of picture elements to a face II opposite to the light incident face I. The light made incident in the dead band is reflected especially concentratingly onto a photoelectric conversion section 1, then even if the radiated light from an object with a small sight angle is concentrated on the dead band, the incident energy is detected. Thus, the hidden image due to the object position is avoided with respect to the small sight object and the sensitivity is improved to an object with a large sight angle. Thus, the utilizing efficiency of the incident light is improved by concentrating the transmitted light through the dead band onto the photoelectric conversion section 1 in this way.</p> |
