Abstract
A technique for generating an image having multiple hues includes filtering first photons at a first wavelength range using a first input filter section of an input filter, and filtering second photons at a second wavelength range using a second input filter section of the input filter. The first photons are directed towards a tube pixel set of a sensor, and the second photons are directed towards the tube pixel set. The first photons and the second photons are detected at the sensor. The first photons are received using a first output filter section of an output filter, and the second photons are received using a second output filter section of the output filter. An image is generated from the first photons and the second photons.
Claims21
A multi-hue intensified image generator comprising:
- an input filter for receiving photons and filtering received photons, said input filter comprising sections for filtering photons of a predetermined hue;
- an image intensifier for receiving filtered photons from said input filter, said image intensifier multiplying said photons;
- an output obscurant directing photons from said image intensifier;
- an output filter for receiving filtered and intensified photons from said image intensifier, said output filter comprising sections for filtering photons of a predetermined hue, said sections movable using a displacement device;
- and
- a multi-hue display device for displaying a multi-hue intensified image comprising a display that displays an image perceived as having multiple hues when said input filter and said output filter are moved at a sufficient frequency.
A method of generating an intensified multi-hue image comprising:
- providing a first filter for receiving photons, said first filter comprising sections for filtering received photons of predetermined hues;
- providing an image intensifier for receiving filtered photons from said first filter;
- providing an output obscurant directing photons from said image intensifier;
- providing a second filter for receiving filtered and intensified photons from said image intensifier, said second filter comprising sections for filtering received photons of predetermined hues;
- providing an output device for receiving photons from said second filter and generating a displayed image using said received photons;
- and
- moving said first filter and said second filter using at least one displacement device, said first filter and said second filter being moved at a frame rate that generates a displayed image on said phosphor screen perceived as having multiple colors.
A multi-hue image intensifier comprising:
- means for input filtering received photons;
- means for intensifying receiving photons from said means from input filtering, said means comprising a microchannel array;
- means for output filtering, said means operable to receive photons from said means for intensifying, said means further comprising an output obscurant directing photons from said means for intensifying;
- means for receiving output, said means operable to receive photons from said means for output filtering;
- means for moving said input filtering means and said output filtering means.
