Abstract: Mating faces of a microchannel plate (MCP) (50) and a multi-layer ceramic body (80) unit are deposited with a thin film having protuberances (84) using a suitable metal selected for optimum diffusion at a desired temperatures and pressure. The metallized MCP (50) and multi-layer ceramic body (80) unit are then aligned and placed in a bonding fixture (F) that provides the necessary force applied to the components to initiate a diffusion bond at a desired elevated temperature. The bonding fixture (F) is then placed in a vacuum heat chamber (V) to accelerate the diffusion bonding process between the MCP (50) and the multi-layer ceramic body unit (80).

Abstract: A faceplate (F) for an image intensifier tube (10) for reducing veiling glare begins as a blank (36) of optical material of a desired glass composition having a shape that conforms substantially to a configuration of the faceplate (F) to be produced. An extraneous removable aperture step portion (54) is formed on the glass blank (36). The glass blank is blackened (41) and the aperture step portion (54) is removed creating a desired transmissive aperture (34) through the glass blank (36).

Abstract: An event synchronizing apparatus E for an image intensification camera system C for gathering image data includes an image intensifier 348 for amplifying received light 312. A relay optic assembly 316 is coupled between the image intensifier 348 and a digital image sensor 350, such as a CMOS or CCD device. Digital logic 352 is used to process or output an image or related data 334. An event detector 340 digitizes an input signal 342 from an illumination source 338 and generates an electrical output synchronization signal 346 in response to the input optical signal 342. The image intensifier camera C derives imaging and control information for the synchronization signal.

The photocathode (20) also includes integral spacer structure (42) which extends toward and physically touches a microchannel plate (22) of the image intensifier tube in order to establish and maintain a desirably precise and fine-dimension spacing distance “G” between the photocathode and the microchannel plate. A method of making the photocathode and a method of making the image intensifier tube are described also.

Abstract: A Fourier transform is applied (205) to a received multiple-carrier phase-modulated signal. The output of the transform includes real and imaginary elements that are associated with the multiple carriers. These elements are processed to provide a magnitude (209) and a sign (211) for the quadrature, Q, and in-phase, I, components of the desired signal. Q and I are processed (213) to yield the desired output signal that approximates the originally obtained signals that were phase-modulated and transmitted on the multiple carriers.

Abstract: An image processing system and method visually documents and displays changes between historical and later mammographic images, preferably in three dimensions. A composite image is created which visually emphasizes temporal differences between the historical and later images. Preferably three-dimensional, digitized images, displayable in various projections, are stored for archival purposes on computer readable media. An image processor preferably exploits an optical correlator to register the historical and later images accurately and provide correlation values as temporal scalars of the differences. The registered images are then compared, voxel-by-voxel, to detect temporal differences. The composite image is displayed with synthetic colors or other visual clues to emphasize apparent changes (for example, tumor growth or shrinkage).
