  • Diffractive phase filter having near field wavelength dependent focusing properties
    Patent number: 4079411
    Abstract: A phase grating structure is defined in which a series of predetermined sawtooth phase delay steps has the property of focusing respective wavelength components of a spectrum of incident wave energy in accordance with their wavelength at different spots in the near field. Although not limited thereto, the invention has particular utility for spatially separating the color components of polychromatic light. Useful applications for this phase filter include (1) recording color pictures on black-and-white film for display in full color, and (2) a single-gun color television camera.
