    摘要： A compact optical memory (100) in which data is stored in an optical data layer (100) capable of selectively altering light such as by changeable transmissivity, reflectivity, polarization, and/or phase. The data is illuminated by controllable light sources (106) and an array of multi-surface diffractive imaging lenslets causing a data image to be projected onto an array of light sensors (108) by reflecting, hence folding the image rays, by means of a mirror (128) that both reflects and optically modifies the light rays to redirect them onto the sensor array (108) located substantially coplanar with the data layer. Data is organized into an annular array of patches (called pages). By selective illumination of each data page, one of the lenslets images the selected data page onto a central image plane where the sensor array (108) is located. Light in the data image pattern strikes different ones of the arrayed light sources, thereby outputting a pattern of binary bits in the form of electrical data signals.

    摘要： An optical memory (10) is disclosed in which data is stored in an optical data layer (19) capable of selectively altering light such as by changeable transmissivity, reflectivity, polarization, and/or phase. The data is illuminated by controllable light sources (15) and an array of multi-surface imaging lenslets (21) project the image onto a common array of light sensors (27). Data is organized into a plurality of regions or patches (called pages) and by selective illumination of each data page, one of the lenslets (21) images the selected data page onto the light sensors (27). Light in the data image pattern strikes different ones of the arrayed light sensors (27), thereby outputting a pattern of binary bits in the form of electrical data signals. By selectively and sequentially illuminating different ones of the data regions (pages) on the data layer (19), correspondingly different data patterns are imaged by the corresponding lenslets (21) onto the common sensor array (27), thereby enabling many stored data pages to be retrieved by multiplexing at electro-optical speed.

    摘要： A fully optical random access memory device is disclosed having an opto-electronic substrate. A write beam, having a wavelength within the absorption band of the opto-electronic substrate, and a read beam, having a wavelength outside the absorption band of the opto-­electronic substrate, are used to read and write information to the fully optical random access memory (26). The noninvasive optical reading of information provides a device capable of sub-nanosecond access times.

    摘要： A fiber optic recirculating memory comprises a splicefree length of optical fiber (10, 134) which forms a loop (14, 130) that is optically closed by means of a fiber optic coupler (20, 136). The coupler (20, 136) couples an optical signal input pulse to the loop (14, 130) for circulation therein, and outputs a portion of the signal pulse on each circulation to provide a series of output pulses. A pump source (34, 140) is included to pump the fiber loop (14, 130) with a pump signal having sufficient intensity to cause stimulated Raman scattering in the fiber loop (14, 130), and thereby cause amplification of the circulating signal pulse. The fiber characteristics, coupler characteristics, and pump power are selected to yield a Raman gain which compensates for the total roundtrip losses in the fiber loop (14, 130), so as to provide an output pulse train of constant amplitude pulses. The invention may be implemented utilizing a standard coupler (20, 136) with a pump signal modulation technique. The pump signal is input to the loop (14, 130) as a series of pulses having a duration and a periodicity chosen to prevent overlap of recirculating pump pulses with input pump pulses until at least two circulations of the loop (14, 130), which minimizes pump power fluctuations and will therefore enhance output signal stability.

    摘要： A memory comprises a multilayer film (1) in which each layer (2) is capable of carrying a charge, built up by successive deposition of a plurality of monomolecular layers (2), at least one of which has been deposited by a process of chemisorption and a photo-injector layer(D) is located on one side of the film for introducing charges into the film in a time sequence which corresponds to the information to be carried. Means (6) are provided for applying a voltage between the faces of the film to cause the charge carried by any layer to be transferred to the adjacent layer. The sequence of charges carried by the film may be read out by a photon-emitting electron arrival detector (F) on the opposite side ofthefilm, or by a method of current differentiation. The film (1) is preferably formed of a polydiacetylene.
