| titleOfInvention | Optical ultrasonic microphone |
| abstract | An acoustic waveguide (6) that transmits sound waves received from the opening (4), a photoacoustic propagation medium (2) that forms at least a part of the wall surface of the acoustic waveguide (6), and an LDV head (8) The photoacoustic propagation medium (2) receives a sound wave that travels through the acoustic waveguide (6) and generates a refractive index change due to the progress of the sound wave in the photoacoustic propagation medium (2) with high efficiency. By taking out as optical modulation by the LDV head (8), an extremely wide-band optical ultrasonic microphone is formed. |
