IPC: G02F1/11
Filed: 1987-12-07
Abstract: PURPOSE:To simplify and miniaturize a device and to reduce a cost by inclining the light emission face of an acoustooptic medium to an attaching face and forming the face opposite to the attaching face into a light-transmitting face. CONSTITUTION:A light emission face 21b is inclined to an attaching face 21e so that a proper quantity of light is reflected on the light emission face 21b and is taken out of an acoustooptic medium 21, and a face 21f opposite to the attaching face 21e is made light-transmissive. Therefore, a part of the transmitted light emitted from the light emission face 21b is reflected and separated and is emitted to the outside from the light-transmitting face 21f and is used as the monitoring light, and a beam splitter is not required when the monitor is necessary. Thus, an optical modulating element is obtained which takes out the monitoring light by a low-cost and compact optical system.
