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.

A method of forming an acousto-optic image by using a plate-like image sensor capable of increasing its optical density upon exposure to a radiation, said method comprising the steps of:
- exposing said image sensor to a radiation bearing image information to record the image information on said image sensor;
- applying pulsed light to said image sensor to enable the same to generate a pressure wave commensurate with the recorded image information;
- detecting the pressure wave in synchronism with said pulsed light to convert said pressure wave into an electric signal;
- and
- reproducing an image from said electric signal.
A device for forming an acousto-optic image, comprising:
- a plate-like image sensor capable of increasing its optical density upon exposure to a radiation;
- first exposure means for exposing said image sensor to a radiation bearing image information to record the image information on said image sensor;
- second exposure means for applying pulsed light to said image sensor to enable the same to generate a pressure wave commensurate with the recorded image information;
- detecting means for detecting the pressure wave in synchronism with said pulsed light to convert said pressure wave into an electric signal;
- and
- image reproducing means for reproducing an image from said electric signal.
An acousto-optic camera comprising:
- a light-shielding housing for accommodating a plate-like image sensor capable of increasing its optical density upon exposure to a radiation, said light-shielding housing having means for exposing said image sensor to a radiation bearing image information to record the image information on said image sensor;
- exposing means in said light-shielding housing for applying pulsed light to said image sensor to enable the same to generate a pressure wave commensurate with the recorded image information;
- and
- detecting means in said light-shielding housing for detecting the pressure wave in synchronism with said pulsed light to convert said pressure wave into an electric signal.
