Title: Electromechanical optical modulating element
Inventor: SATO HIROSHI
IPC: G02B26/02
Filed: 1985-09-11
Abstract: PURPOSE:To control the quantity of signal light on an image formation surface by varying the angle of deflection of a specific mirror oscillation part and deviating part of the signal light from the entrance pupil of an image forming lens. CONSTITUTION:The mirror oscillation part 13 of an electromechanical optical modulating element 23 varies in angle theta of deflection with an impressed voltage V on constitution conditions (b), (l), (t), and (h). This variation deviates part of the signal light from the entrance pupil of the lens 24 which forms an image of light from a modulating element 23 on a photosensitive drum 26. A large correction is made by varying the hinge width (b) of the modulating element and a fine irregularity in the quantity of light is corrected by the impressed voltage V. In this constitution, the quantity of signal light on an image plane is adjustable without increasing the parts of a recording device such as a printer and the SN ratio of a signal is increased.
