Abstract:

Methods and apparatus for truncating an image formed with coherent radiation. The optical relay system is adapted to form a line image at the image plane. The image is truncated by a variable aperture at or near the aperture plane conjugate to the image plane, to block progressively increasing portions of an incident coherent radiation beam used to form the line image. An apodizing pupil filter having a maximum transmission or reflection in the center and a transmission or reflection profile that varies with direction corresponding to long direction of the line image is provided in the pupil plane. The apodization is designed to prevent hot-spots from forming in the truncated image and ensures a relatively smooth, flat intensity profile. Thus, one end or another of a coherent line image scanned over a substrate can be truncated during scanning without substantially changing the image intensity extending into the product area.

Abstract:

Disclosed is fresnel lens apparatus for optically coupling a plurality of data channels between stationary and rotating systems. Each data channel of the apparatus includes an optical data transmitter, an optical data receiver and a fresnel lens optical element. The plurality of fresnel lens optical elements are preferably annular and arranged concentrically in a plane. Each fresnel lens optical element focuses the optical data from a transmitter to a respective receiver which is positioned off axis with respect to the central axis of the concentric optical elements.

Abstract:

A photographic, digital or video camera (10) includes a housing (12); optionally at least one sensor (18, 20, 25, 30, 36, 39, 40, 50) supported by the housing for detecting a condition of the camera or of a scene to be captured by the camera, or both, and for producing a signal; a viewfinder (38) supported by the housing, the viewfinder including a holographic element 64, 90); a source (68) of light having a wavelength of a color to be displayed in the viewfinder; a collimator (70) for receiving a beam from the source and producing an output beam; an optical system (72-80) to horizontally and vertically raster scan the output beam across the holographic element; and a controller (44) for operating the optical system and modulating the output beam in response to the signal, thereby to cause scanned images to be produced by interaction between the output beam and the holographic element, the scanned images displaying information related to use of the camera.

US Classification:

2504951

Abstract:

An infrared illumination system for a digital camera having a taking lens, includes: a plurality of infrared emitting diodes arranged around the taking lens, each diode being contained in a can having an infrared transparent window; a first diffuser located over the windows of the cans; and a second diffuser spaced apart from the first diffusers. The first diffuser is a new type of diffuser called a Fourier transform holographic diffuser.

International Classification:

G03B 2900
G03B 1724

US Classification:

396319

Abstract:

Respective image representations of a scene in front of a camera are recorded on a recording medium, such as a filmstrip, when the camera is at two separated viewpoints with respect to the scene, in order to obtain a matched pair of right-eye and left-eye pictures that can be simultaneously viewed to present a stereoscopic image of the scene. Respective indications are recorded on the recording medium, distinguishable from the image representations, that the image representations were recorded with the camera at the two separated viewpoints with respect to the scene. Thus, the matched pair of pictures can be kept in the right order for stereoscopic right-eye and left-eye viewing.

International Classification:

G03H 104

US Classification:

359 10

Abstract:

A holographic recording of the interference between an object laser beam and a reference laser beam is used to combine the amplitudes of multiple laser beams which are conjugates of the reference beam into a single laser beam which is conjugate of the object beam. An optical device in the form of a prism has an entrance face with a diffusion surface, and an exit face with a light sensitive recording medium. An object beam incident on the diffusion surface is scattered over the recording medium, in interference with a reference beam simultaneously incident at an angle. theta. onto the same medium. Multiple beams, conjugate to the reference beam, incident at angles. theta. +-. 4. degree. on the hologram thus created on the recording medium are diffracted by the hologram and caused to combine at the diffusion surface to form a signal output beam, conjugate to the original object beam and having an amplitude which is proportional to the sum of the separate amplitudes of the combined beams.

International Classification:

F21K 500

US Classification:

431360

Abstract:

A photoflash lamp comprising a lamp housing, a combustible material burning inside the lamp housing to produce a flash illumination, and ignition means for igniting the combustible material, is characterized by optical element means on the lamp housing for changing from a substantially uniform thickness to being thicker in a center than at an edge, responsive to the lamp housing becoming heated when the combustible material is burned inside the lamp housing to produce the flash illumination. The optical element, when changed from a substantially uniform thickness to being thicker in the center than at the edge, forms a positive lens that converges the light rays during flash illumination to enhance the light output.

Abstract:

A holographic recording of the interference between an object laser beam and a reference laser beam is used to combine the amplitudes of multiple input laser beams which are conjugates of the reference beam, into a single output laser beam which is a conjugate of the object beam. An optical device in the form of a trapezoidal prism has an entrance top face with a diffusion surface, and an exit base face with a holographic recording made on a light sensitive recording medium of an interference pattern of an object beam incident on the diffusion surface and scattered over the recording medium, in interference with a reference beam simultaneously incident to a side of the prism onto the same medium. Multiple beams, conjugate to the reference beam, are positioned to be incident on the holographic recording, the hologram being configured to diffract the multiple beams and cause them to be combined at the diffusion surface to form a single output beam, conjugate to the original object beam and having an amplitude which is proportional to the sum of the separate amplitudes of the combined beams.
