<p>PURPOSE: To improve detection capacity by synthesizing a channel for detecting near-infrared rays and a channel for detecting the other parts within a visible spectrum in the range of a specific wavelength. CONSTITUTION: A main channel 1 supplies incidence beams of 400nm-1,000nm via an image pick-up tube or a detection tube 12 and a video signal to an electronic control/output circuit 13. A color channel 2 supplies incidence beams to a control/output circuit 23 via an image pick-up tube 22 through an optical filter 24 for eliminating an infrared-ray part with a wavelength of approximately 700nm or longer. The circuits 13 and 23 are synchronized each other via a line 27, the output signal of the circuit 23 is subjected to clipping/time integration via an electronic filter 25, and the channels 1 and 2 are supplied to the different electron guns of a color monitor 28, thus obtaining information regarding the main channel with an expansion spectrum with the maximum degree of detection and resolution and at the same time, obtaining additional information regarding the contrast between substances due to color distribution at the color channel part and hence improving detection capacity.</p> |
