OPTICAL MODULATION BY FLUIDIC OPTICS UTILIZING CHROMATIC ABERRATION

摘要

Optical modulation in the ultraviolet, visible and/or infrared spectrum, for a range of uses including optical computers, data-processing and optical information processing systems together with the transduction of gas and liquid fluidic signals and pressure transients to optical and electrical signals, a fluidic optic such as a transmission or reflection elastic lens which includes a fluid-oscillable elastic wall, typically a fluid-filled chamber having at least one elastic wall driven by alternating flow or pulse fluid oscillation means, optically coupled with a light source like a laser which generates at least two different wavelengths, and a sensor. The fluidic optic separates the wavelengths by chromatic aberration, and a stop between the optic and the sensor passes a given wavelength while blocking other wavelengths during a given oscillation mode. The oscillable wall of the fluidic optic can include an elastic or deformable image, diffraction grating, polarizer or hologram.
