摘要： L'invention concerne un dispositif d'holographie numérique, et s'applique par exemple à la cartographie tridimensionnelle des objets.
Le dispositif selon l'invention permet de déterminer l'amplitude complexe d'une onde signal (WS 2 ) issue d'un objet (DUT) éclairé par une onde d'illumination (WS 1 ) connue. Pour cela, II comprend

des moyens (LAS, AOM 1 , AOM 2 ) de génération de deux ondes cohérentes entre elles, l'onde (WS 1 ) d'illumination de l'objet, et une onde de référence (WREF) connue, les deux ondes présentant une différence de phase connue φ i (t) fonction du temps,
des moyens (BS) pour faire interférer, sur des moyens de détection (DET), l'onde (WREF) de référence et l'onde signal (WS 2 ) issue de l'objet, les moyens de détection permettant un échantillonnage de la figure d'interférence résultant en l'acquisition d'un nombre N donné d'interférogrammes, N supérieur ou égal à 2, correspondant chacun à une différence de phase distincte entre l'onde signal et l'onde de référence incidentes sur les moyens de détection, l'amplitude complexe de l'onde signal étant alors déterminée à partir du traitement desdits inteférogrammes.

摘要： Provided is an observation device which can obtain a phase image of a moving object rapidly with high sensitivity even when using a photodetector having a slow read-out speed per pixel. The observation device 1 comprises a light source 10, a first modulator 20, a second modulator 30, a lens 40, a beam splitter 41, a photodetector 46, and an arithmetic unit 50. The lens 40 receives scattered light generated by a moving object 2 and forms a Fourier transform image of the object 2. The photodetector 46 outputs data representing a sum in a v direction of data temporally changing at a frequency corresponding to a Doppler shift frequency of the light having reached each position on a light-receiving surface through the lens 40 at each position in a u direction at each time. The arithmetic unit 50 obtains an image of the object 2 according to the output of the photodetector 46.

摘要： The inventive method for opto-acoustical imagery of an image object (OBJ) consists in a) generating an incident optical wave (INC) and a reference optical wave (REF) coherent therewith, b) oscillating the image object (OBJ) area at an acoustic frequency, c) sending the incident wave (INC) to said image object (OBJ), thereby generating a diffused signal wave (DIF), d) sending at least one part of said diffused signal wave (DIF) to a detection device (DET), e) sending the reference optical wave (REF) to the detection device (DET) avoiding the image object (OBJ), thereby generating an interferogram I (r, t), f) extracting digital information from said interferogram I (r, t), and in g) obtaining co-ordinates (U, V, W) from one measurement point of the image object (OBJ) associated to said digital information.
