    摘要: A block of composite material includes a dielectric material with a dielectric constant of .epsilon..sub.d =4.66 and which is at least 4 .mu.m thick and has electrically conductive microparticles randomly distributed throughout. The composite material exhibits an optical bistability without cavity feedback. The microparticles must be nearly uniform in size and of spherical diameter much smaller than the wavelength of light in the particle. The composite, when illuminated by laser light in the range of 500 nm and of varying intensity, becomes opaque at a critical input intensity and stays opaque until the input intensity reaches a certain level both below and above the intensity at which it initially became opaque. Thus the material behaves as an optical switch and a limiter.

    摘要: An opto-electronic device utilizes a band of partially polarized polychromatic light for quantitative analysis of a specimen containing a target molecule. The device comprises: a polarizer for producing a segmented band of partially polarized polychromatic light from the band of partially polarized polychromatic light; a specimen cell adapted for receiving the specimen and for transporting said segmented band of partially polarized polychromatic light to the specimen; a polarizing analyzer optically coupled to said segmented band of partially polarized polychromatic light exiting the specimen; and comparison means for comparing said segmented band of partially polarized polychromatic light before entering the specimen with said segmented band of partially polarized polychromatic light after exiting the specimen. The target molecule changes ellipticity of said segmented band of partially polarized polychromatic light and said polarizer is synchronized with said polarizing analyzer.
