ABSTRACT:
An acoustooptic image can be formed by using a plate-like image sensor capable of increasing its optical density upon exposure to a radiation. The image sensor is exposed to a radiation bearing image information to record the image information on the image sensor. Then, pulsed light is applied to the image sensor to enable the same to generate a pressure wave commensurate with the recorded image information. The pressure wave is detected in synchronism with the pulsed light and converted into an electric signal, from which an image signal is reproduced. The image signal may be displayed on a CRT, or recorded on a magnetic recording medium, or reproduced on a photographic material.
