Acousto-Optic Effect and Modulation
| 실험 내용 | Bragg cell, acousto-optic modulator, Study of diffracted beams as a function of the frequency of the acoustic wave, Determining the diffraction Bragg angle, |
|---|---|
| Calculation of the acoustic wavelength and time of access, Assessment of the speed of sound wave in the material, Measuring the diffraction intensity according to the power of the acoustic wave, | |
| Calculating the diffraction efficiency and absorption of the acousto-optic material(TeO2),Acousto-optic deflector: application to the projection and optical addressing | |
| Study of acousto-optical modulation: application to registration and transmission of an electrical signal(sine, square, triangle, audio) on a laser beam | |
| . | |
| 실험 목적 | The user of this lab will initially determine several parameters characterizing the acousto-optical medium(transmittance, Bragg angle, velocity of the acoustic wave, the diffraction efficiency ...). |
| Then he will have to study and discuss two applications of deflection and intensity modulation. | |
