摘要： The present invention pertains to a process for the stabilization of Holograms formed on gelatin. According to the invention, after (i) exposing, (ii) developing, and (iii) quenching said Hologram, there is added thereto (iv) a bleaching bath based on an oxidative cross-linking agent at a pH value of at least 3 or more, and thereafter, following (v) rinsing, (vi) fixing, (vii) additional rinsing and (viii) a final bath, (ix) said support material is dehydrated by the use of one or more baths in series containing a solvent which is water-miscible and does not affect the cured gelatin structure. In another embodiment, the invention pertains to light-directing wall elements for buildings made of a Holograms obtainable by the process mentioned above and applied to a transparent or opaque substrate. By means of the present invention, silver-free holographic support materials can be prepared.

摘要： A method for direct phase measurement of radiation, more particularly light radiation, which is reflected by a body or object with a diffusely reflecting surface. In order to make possible measurement of the phase with the production of a single image, the object or body is irradiated with coherent radiation having a predetermined frequency. The reflected radiation is used to produce an image in an image plane using an image forming optical system, a sensor with a plurality of preferably regularly arranged sensor elements being located in the plane. There is a superimposition of reference radiation on the sensor with the same frequency and with a defined phase relationship. In the case of directed object rays coming from a mirror-like body or object, the reference beam is set so that one period of the interference field produced on the sensor by the superimposition of the object and reference beams covers at least three sensor elements. The image forming optical system is designed and set so that the images of the speckles produced by the radiation on the object or body cover at least three sensor elements in the image plane. The phase of the radiation from the object or body is determined on the basis of the intensity signals of the at least three sensor elements.
