HOLOGRAPHIC RECORDING APPARATUS AND METHOD |
摘要 |
Disclosed is a hologram recording apparatus which comprises: a stage unit which holds a hologram recording medium and is able to drive; a hologram recording optical system which has a light source unit for emitting a coherent light, separates a beam emitted from the light source unit into a reference beam and a signal beam, modulates the signal beam, and irradiates the modulated signal beam and the reference beam onto the hologram recording medium; a real-time vibration detection system which detects vibrations of the stage unit; a vibration signal processing unit which generates a light source control signal by processing the vibration detected from the real-time vibration detection system as a signal; and a control unit which controls the light source unit according to the light source control signal generated from the vibration signal processing unit. [Reference numerals] (100) Light source unit; (200) Signal beam optical system; (300) Reference beam optical system; (400) Stage unit; (500) Driving unit; (600) Real-time vibration detection system; (700) Vibration signal processing unit; (800) Damping system; (900) Control unit |
