Abstract

PURPOSE:To make it unnecessary to reduce and project optical picture information and make a bias power source needless, by using amorphous Si to constitute the photodetector constituting a photodetecting plate. CONSTITUTION:When optical picture information is projected to photodetecting palte 1 from the substrate 2 side, electromotive force corresponding to the light quantity of optical picture information is generated between electrodes 3 and 7 of photodetector M1. After obtaining this state, electric picture element information S1-SN are obtained successively between output lines 9a and 9b when scanning pulses P1-PN are applied successively from output terminals T1-TN of scanning pulse generating circuit 12 to switch elements Q1-QN. These information S1-SN are supplied to picture information processing circuit 10 as electric time series picture information indicating optical picture information projected to photodetecting plate 1. In this case, photodetectors obtained by using an amorphous Si layer to form P-N junction are used as photodetectors M1-Mi. As the result, the optical device which reduces and projects optical picture information and the bias power source are needless.
