| titleOfInvention | A multi-channel acoustooptic modulator in which openings of each cell are connected in series |
| abstract | The present invention relates to a multi-channel acousto-optic modulator. The number of pixels is limited to several thousand or less in an acoustooptic modulator in which a plurality of piezo transducers are attached to one acoustic optical modulator cell, and thus it has been limited to use in a display device requiring tens of thousands of pixels such as a holographic video system. According to an aspect of the present invention to overcome these limitations, there is provided an acoustooptic modulator for acoustically modulating incident light, the acoustooptic modulator including a plurality of modulator cells, and a plurality of modulators arranged between the plurality of cells, And a plurality of sound absorbing plates for isolating and connecting the cells to each other. Wherein each of the cells has a unit cross section in a symmetrical reciprocal trapezoid shape and is formed of a unit crystal for diffracting or transmitting the incident light by modulating the incident light, a pair of electrodes coupled to the upper crystal plane of the unit crystal, A piezoelectric transducer for generating an acoustic wave in the unit crystal in accordance with a signal that is lost, and an acoustic absorber coupled to the upper crystal plane of the unit crystal to absorb acoustic waves from the unit crystal. The present invention increases the number of displayable pixels by connecting each acoustooptic modulator cell in a straight line, thereby creating an optical modulator cell having a long aperture. Since each acoustic optical modulator cell can operate independently, high-speed input becomes possible and a pulse laser can be used as a light source. |
