| A method for effecting the desired optical characteristics of an optical system (10) using phase diffractive optics. Incident light (Bi) is directed onto a surface (12i) of a material (12) whose index of refraction (n) is variable over the material. Passage of the incident light through the material effects the phase and amplitude of the light waveform. An optical map (Om) is determined for the surface of the material. This map comprises variations in the index of refraction over the material surface, and the map, in effect, represents any of a range of refractive and diffractive optical elements such as a mirror (1), a lens (2,3,6,7), or a diffraction grating (100). The map is dynamically written onto the material to map the material such that the incident light's passage through the material corresponds to the passage of the light through the optical element currently emulated by the material. As a result, emergent light (Be) from the material has similar amplitude and phase characteristics as if the incident light had passed through the desired optical element. | ||||||

| A spatial light modulator includes a device portion and a bias field applying coil disposed around the device portion. The device portion includes a magnetic layer and two types of conductor layers. The magnetic layer is made of a magneto-optic material and includes a plurality of pixels whose directions of magnetization are set independently of one another. Each of the pixels causes rotation of a direction of polarization of incident light depending on its direction of magnetization due to a magneto-optic effect. The conductor layers generate a magnetic field for setting the direction of magnetization of each of the pixels of the magnetic layer. The magnetic layer has grooves for defining the borders of the individual pixels. The grooves are formed to extend from the top surface of the magnetic layer to a predetermined position between the top and bottom surfaces of the magnetic layer. | ||||||

| The twin-image elimination apparatus of the present invention comprises (a) a scanning light source for emitting a scanning light beam; (b) an interference device which converts the scanning light beam from the scanning light source into a spherical wave and a plane wave having temporal frequencies different from each other and combines the spherical and plane waves together; (c) a scanner for scanning an object with the combined light beam from the interference device; (d) a photodetector for detecting a scattered wave from the object; (e) a first multiplier which converts an output signal of the photodetector into a cosine-coded holographic information; (f) a second multiplier which converts the output signal of the photodetector into a sine-coded holographic information; and (g) a holographic reconstruction device which converts output signals of the first and second multipliers into a sum signal, in which these output signals are added together with a phase difference of .pi./2+2n.pi. (wherein n is an integer not less than 0), so as to reproduce an image of the object without the presence of its twin image. Hence, at the time of reconstructing a hologram, the virtual image component contained in the output signal of the photodetector can be removed, thereby improving the image quality of the reconstructed image. | ||||||

| There is disclosed an optical heterodyne scanning holography device capable of recording and reconstructing a holographic image of an object in real time by optical heterodyne-scanning the object, capturing a scattered wave from the object by a photodetector, and converting a heterodyne output current from the photodetector to a spatial light modulator for coherent processing optically. | ||||||

| PROBLEM TO BE SOLVED: To remove a real image or virtual image and to improve the picture quality of a reproduced image by providing 1st and 2nd specific multipliers and reproducing an image of a body with the signal generated by adding the output signal of the 1st multiplier and the output signal of the 2nd multiplier while giving a specific phase difference between them. SOLUTION: A 1st multiplier 25 which cosine codes the output signal of a photodetector and a 2nd multiplier 28 which sine codes the output signal are provided, and 1st and 2nd spatial modulators where image information on the body is recorded on the basis of the output signals of the multipliers 25 and 28 are provided. Then a phase unit 27 generates a phase difference of π/2+2nπ between a read light beam modulated by the 1st spatial optical modulator and a read light beam modulated by the 2nd spatial optical modulator and a body image reproducing device 55 puts the read light beams which are modulated by the 1st and 2nd modulators together to reproduce the image of the body, thereby eliminating a double image.
