Abstract
Abstract A simplified color TV system having specified frame and field rates generates a number of successively repetitive discrete bandwidth spectra within a number of respective different color spectra to irradiate a subject. The irradiation is either transmitted through or reflected from said subject to a single electron gun vidicon tube for transducing the optical images of the irradiated subject into electrical signals. The electrical output of the vidicon tube may be fed to a conventional threeelectron gun color TV tube for monitoring the images. The three electron guns of the monitor are controlled in accordance with the electron image output of the vidicon tube, representing the discrete bandwidth spectra, to provide an integrated color image of the subject on the monitor. The simplified TV system obviates the necessity of a conventional three-beam vidicon to detect the color images reflected or transmitted through the subject. This is accomplished by strobing the subject with successive repetitive narrow bandwidth spectra generated by prisms, transmission diffraction gratings, diffraction gratings, interference filters or pulsed laser sources. The generation of the discrete bandwidth spectra is synchronized with the field rate of the color TV system.
