Title:
PHOTOACOUSTIC IMAGE FORMING DEVICE AND METHOD
Document Type and Number:
Japanese Patent JP2020014728
Kind Code:
A
Abstract:
To acquire a high-resolution image of inside of an analyte in a non-contact manner and in real time.SOLUTION: A photoacoustic image forming device comprises: a light radiation unit for emitting pulsed light of a wavelength which is absorbed in the analyte; a thin film which is pasted or applied to a skin surface of the analyte, has flexibility as a whole, transmits the pulsed light and simultaneously reflects the light at an external surface thereof; a multi-direction light radiation unit for simultaneously emitting a plurality of visible lights to the external surface of the thin film from multiple directions; a minute vibration detection unit for detecting a state in which the photoacoustic wave generated from the light absorber collides with a rear inner surface of the thin film and slightly vibrates the thin film on the basis of diffraction and/or interference of the plurality of reflected lights acquired from the external surface of the thin film; and a shape image conversion unit for making an image of a shape of the light absorber on the basis of the vibration state of the thin film detected by the minute vibration detection unit.SELECTED DRAWING: Figure 2
