Class Information
Number: 356/308
Name: Optics: measuring and testing > By dispersed light spectroscopy > With synchronized spectrum repetitive scanning (e.g., cathode-ray readout)
Description: 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.
