摘要： Method for observing a sample (10) including a step of illuminating the sample with a light source and recording, with a photodetector (16), a plurality of images, the images representing the light transmitted by the sample in various spectral bands. From each image, a complex amplitude representative of the light wave transmitted by the sample in a given spectral band is determined. The method, which is iterative, then comprises: back-propagating each complex amplitude to a plane of the sample; calculating a weighting function from a weighted sum of the back-propagated complex amplitudes; propagating said weighting function to the plane of the photodetector; updating each complex amplitude, in the plane of the sample, depending on the weighting function thus propagated.

摘要： An optical device 50 including a hologram recording medium 55 that can reproduce an image of a reference member and an irradiation unit that emits a coherent light beam to the optical device 50. The irradiation unit 60 includes a light source for emitting a coherent light beam and a scanning device 65 capable of adjusting a reflection angle of the coherent light beam emitted from the light source and that makes a reflected coherent light beam scan the hologram recording medium. The light source has light sources for emitting coherent light beams having different wavelength ranges. The hologram recording medium 55 has a plurality of recording areas to be scanned with a plurality of coherent light beams reflected by the scanning device 65, respectively. Each of the plurality of recording areas has an interference fringe that diffracts a coherent light beam of the corresponding wavelength range.

摘要： When coating a document surface (3) having relief-like information (1) carrying personal data, for example, with a monomer-containing liquid UV adhesive (4) across the entire surface and then laminating thereon a volume hologram (2), the varying adhesive thicknesses between the volume hologram and the document surface resulting from the relief cause differentiated swelling and thereby a differentiated color shift of the hologram. After the desired color shift is achieved, the UV adhesive (4) is completely cured. In this way, individual holographic information is obtained, which is located exactly above the relief-like information of the document. With this method, holographic overlays comprising personal data and a passport picture can be produced, and it is possible to link defined optical document information to the hologram in an accurately positioned manner, so that information is visible both non-diffractively and, from a different viewing angle, holographically in a different color.

摘要： A reduction in speckle patterns in the reconstruction of a 3D scene can be achieved by way of averaging. In a holographic reconstruction device, speckle patterns are intended to be suppressed while taking account of the visible resolution of the reconstruction of the scene. The holographic reconstruction device is designed such that the visible resolution of the reconstruction of the scene is matched to the resolution capability of the human eye, to the imaging properties of the reconstruction means (RM) used or to the resolution capability of the light modulation means (SLM) used. Method steps are carried out, in which a grid scale for the object points (OP) is generated by way of system control means (SM) in each case in a plane of intersection (SE), which grid scale cannot be used to separately resolve adjacent object points (OP) in the plane of intersection (SE), and the compilation of object points (OP) of the respective plane of intersection (SE) to form an object point group with adjacent object points (OP) which can be separately resolved is carried out. In holographic displays, the invention is used to reduce speckle patterns and reduce the number of the holograms of object points of the scene, which are to be calculated and coded, and the calculation complexity.
