With synchronized spectrum repetitive scanning (e.g., cathode-ray readout):
(under subclass 300) Subject matter which includes the periodic scanning of a dispersed light beam over the optical frequency spectrum, detecting the scanned dispersed beam, synchronizing a visual readout with the various wavelengths present in the detected dispersed beams, and correlating the intensity of the detected readout with each wavelength present in the dispersed beam.
(1) Note. The readout is usually a cathode-ray tube.
(2) Note. The synchronization of the scanning of the dispersed beam is with the movement of the dispersing means, the optical means associated with the dispersing means, or the electronics of the detection and readout circuitry.
