Patent ID: 7483213

Claim:
An image combining viewer, comprising: a housing defining an optical path therethrough; a sensor disposed within the housing, the sensor being structured to receive a wavelength outside the visible spectrum; a display disposed within the housing, the display being adapted to display an image received by the sensor using a portion of the visible spectrum; at least one mirror disposed within the housing, the at least one mirror having a front surface and a back surface, the front surface having a dichroic coating adapted to transmit visible light and to reflect the wavelength outside the visible spectrum, the front surface being adapted to direct the reflected wavelength from the optical path towards the sensor, the back surface having a dichroic coating adapted to transmit a portion of the visible spectrum and to reflect another portion of the visible spectrum, the back surface being adapted to reflect light transmitted by the display to a direction substantially along the optical path; whereby an image transmitted by the at least one mirror and the image displayed by the display are combined into a single image; and means for focusing the sensor.
