1. An integrated color imaging system, comprising:
a housing having an objective lens configured to receive an image of incident electromagnetic radiation from a scene and focus the image on a photocathode of an image intensifier located inside the housing, the image intensifier having a plurality of radiation sensitive sensors and a phosphor screen;
a first filter wheel located inside the housing between the objective lens and the photocathode, the first filter wheel is configured to be rotatable relative to the image intensifier, the first filter wheel comprises a plurality of first channels selectively positionable in an optical path of the image, and at least one of the first channels is clear and unfiltered;
a second filter wheel located inside the housing between the phosphor screen and an eyepiece lens of the housing, the second filter wheel is configured to be rotatable relative to the image intensifier, the second filter wheel comprises a plurality of second channels selectively positionable in the optical path between the phosphor screen and the eyepiece lens, and at least one of the second channels is clear and unfiltered; and
the clear and unfiltered channels of the first and second filter wheels are configured to be selectively aligned in the optical path and retained in stationary positions.
