摘要： Apparatus for measuring the extent and sense of relative movement between two objects comprises a reflecting ruled grating carried on one body and optical reading head carried on the other. The reading head includes a light source arranged to produce at least three light beams which are directed at the grating and reflected therefrom onto a mirror twisted about a line parallel to the grating lines. This mirror reflects the light beams onto a different area of the grating from which they are reflected to separate light-sensitive devices. Lenses are used to focus the light beams as required.

摘要： By providing a given thickness for a positive photoresist layer on a substrate which, if unexposed, after development has a maximum depth just equal to the sum of the individual depths of two, at least partly superimposed, rectangular relief-profile diffraction gratings in the developed photoresist layer, it is possible to make a single master recording, which can be used to provide a stamper for embossing two of the three primary colors in a single surface of a transparent plastic sheet in the fabrication of diffractive subtractive filters.

摘要： A method of producing a diffraction grating master which comprises exposing a plurality of reduced first grating patterns on a light sensitive layer in conformance with a predetermined code; processing the light sensitive layer to produce first gratings therein; exposing a plurality of reduced second grating patterns on the light sensitive layer (superimposed on the first gratings) and repeating the processing step to produce the second gratings; vacuum depositing a layer of silver on the superimposed first and second gratings; electroplating a layer of nickel on the silver layer on the superimposed gratings; separating the resulting nickel-silver layer from the light sensitive layer; and reinforcing the nickel-silver layer (formed in the pattern of the first and second gratings) for use as an embossing master. A special electroplating fixture used in the electroplating step insures that the nickel layer being deposited lies flat without "peeling".

摘要： An optical apparatus using a single source of white light has five independent channels each of which divides that light into three spectral components, and supplies those components individually through individual attenuators for use as a set of fifteen separate and independently-controllable light sources. Fiber optics light conductors bring light from those sources to a transform filter in a Fourier transform optical system.

摘要： An optical low-pass filter which is inserted in an image forming optical system in order to attain the response to zero in a frequency over the cut-off frequency and which is adapted so that the response in said optical system may not undergo a change depending upon the variation of F-number of the optical system. The filter gives a blur to all images formed by said image forming optical system, and is composed of phase elements provided on a transparent base plate. The phase elements are disposed systematically on a base plate for giving the phase difference to the wave front of light ray incident upon said transparent base plate.

摘要： Stereoscopic X-ray photographs form photographic pictures on one or two record carriers on which also gratings are formed. When the pictures are projected through apertures of a diaphragm, positive and negative images having different diffraction orders are produced whose intensities are simultaneously decreased and increased by grey wedges so that the combined image is varied between positive and negative conditions.

摘要： An optical image processor utilizing filtering in the spatial image plane to enhance selected details of an optical image such as a photographic transparency. Spatially coherent light is passed through an optical train including a transparency of a scene to be enhanced and the image of the light source is focused onto a plane containing a spatial filter which may consist of a slit of variable dimension and orientation. The geometric patterns of the scene on the transparency function as diffraction gratings for the coherent light and the desired diffraction patterns are selected by a spatial filter of the appropriate dimension and location. The filter may be rotated to provide a cyclically recurring enhanced image.

摘要： The invention concerns an optical method for processing information represented by the transparency of a two-dimensional document such as a photographic record. Optical methods are known wherein the document is illuminated with a parallel beam of coherent monochromatic light and placed in the object plane of a convergent optical conversion system to form in a spectral plane the spectrum of the function that represents the transparency of the document. A filter is placed in the spectral plane and an optical reconstitution system forms a filtered image of the document. According to the invention, the filter consists of a screen, the transparency of which varies over its surface as the autocorrelation function of the spectrum of the function that represents the transparency of the document.
