Abstract
An electro-optic device is disclosed which has a plurality of independently-gatable portions. One example is an image intensifier having a number of segmented photocathode areas (GP). The corresponding portions of the intensifier can be energized independently via contact stripe (CS). Used in conjunction with an appropriate trigger signal generator, imaging device and beam splitter, the device may be used to capture a series of images at very high speed. An electrical device having a reflective tunnel for generating a plurality of input images is also disclosed.
Claims17
An imaging arrangement adapted to receive two dimensional optical data representative of an object and represented by at least two beams of electromagnetic radiation, the arrangement comprising means for gating and converting the at least two beams into image data includes a single electro-optic device comprising a photosensitive surface, which surface is arranged to comprise a plurality of independently-gatable portions, wherein the independently gatable portions correspond to each of the at least two beams of electromagnetic radiation, each portion being responsive to an image signal, and wherein the means for gating and converting the at least two beams into image data is arranged to provide an image including the object in its entirety to each respective portion of the photosensitive surface.
An imaging arrangement for two dimensional optical data representative of an object and represented by an incident beam of electromagnetic radiation, the arrangement comprising:
- means for splitting the incident radiation beam into a plurality of beams,
- means for gating and converting the plurality of beams into image data,
- wherein the means for gating and converting the plurality of beams into image data includes a single electro-optic device comprising a photosensitive surface having independently-gated portions corresponding to each of the plurality of beams, and each of the plurality of beams corresponds to an image including the object in its entirety.
A method of imaging two dimensional optical data representative of an object and represented by a beam of electromagnetic radiation, the method comprising:
- splitting the radiation beam into a plurality of beams;
- gating the plurality of beams;
- converting the gated beams into image data;
- wherein the gating of the plurality of beams is performed using a single electro-optic device comprising a photosensitive surface having independently-gated portions corresponding to each of the plurality of beams, and each of the plurality of beams corresponds to an image including the object in its entirety.
An imaging arrangement adapted to receive a plurality of images representative of an object, said imaging arrangement comprising:
- an electro-optic device comprising a photosensitive surface, which surface is arranged to comprise a plurality of independently-gatable portions, wherein each respective portion of the photosensitive surface is arranged to gate an image including the object in its entirety, and the electro-optic device is arranged to output the image including the object in its entirety from each respective portion of the photosensitive surface.
An imaging arrangement adapted to receive a plurality of images representative of an object, said imaging arrangement comprising:
- an electro-optic device comprising a photosensitive surface, which surface is arranged to comprise a plurality of independently-gatable portions, wherein each respective portion of the photosensitive surface is arranged to gate an image including the object in its entirety, and the electro-optic device is arranged to output image data corresponding to the image including the object in its entirety from each respective portion of the photosensitive surface.
