Optical unit, method for controlling drive, and holographic apparatus
An optical unit includes an acousto-optic deflector and a drive control unit. The drive control unit controls the acousto-optic deflector by changing a frequency of a voltage applied to an acousto-optic medium of the acousto-optic deflector to a frequency in a first frequency range during a first pe...

| Zusammenfassung: | An optical unit includes an acousto-optic deflector and a drive control unit. The drive control unit controls the acousto-optic deflector by changing a frequency of a voltage applied to an acousto-optic medium of the acousto-optic deflector to a frequency in a first frequency range during a first period representing a deflection control period and changing the frequency of the voltage to a frequency in a second frequency range different from the first frequency range during a second period representing a transmittance control period. |
