摘要： A power limiter is provided consisting of two cells of optically transparent material having a low index of refraction, but a large third order susceptibility to electric polarization. The input cell has a positive susceptibility which self-focuses intense radiation beams (i.e., laser beams) and the output cell has a negative susceptibility which scatters the even more intense self-focused beam by self-defocussing.

摘要： A liquid crystal modified by the addition of an organic dye is used as a non-linear optical material in two devices which limit the optical radiations to sensitive photodetectors. One device uses the self-focusing induced in the crystal to disperse high-intensity optical radiation, the other uses the change of index of refraction of the crystal to effect total reflection of high-intensity radiation from a liquid crystal-linear optical material inter-face

摘要： In order to protect a delicate photodetector from high-intensity radiation, such as from a laser, a device for limiting optical power to the detector is interposed between the radiation and the detector. This device has an optical interface that totally reflects high-intensity radiation, but which freely transmits normal (low intensity) radiation to the detector. The interface is between two optical materials, one with a linear index of refraction with respect to radiation intensity, and the other with a non-linear index. At low intensity radiation levels, the two materials have the same indices of refraction, and such radiation is freely transmitted through the interface, but with high-intensity radiation, a mismatch of indices of refraction allows total reflection at the interface.

摘要： (S) A first optical material with a linear index of refraction is distributed as particles in a second optical material with an index of refraction dependent on the incident radiation intensity. Below some threshold intensity level the combination of materials is transparent to incident radiation directed toward a sensitive optical detector. Above this level, high-intensity incident radiation induces a change in refractive index of the second material, and the combination is limiting to incident radiation.

摘要： This is a new use for known photorefractive crystals. If input radiation taining both non-coherent and multiple-line coherent radiation is directed into such a crystal from a predetermined range of directions with respect to the C axis of the crystal, rainbow scattering of the coherent radiation occurs, whereas normal scattering of the non-coherent radiation occurs. A detector toward which input radiation is directed through the crystal is thus protected from high-power, multiple-line coherent radiation such as that provided by a threat laser.

摘要： A passive broadband sensor protection and enhancement system and technique.ncident light is focused with a cylindrical lens on the optical axis into an intense light strip onto the input face of a photorefractive crystal on the optical axis. The crystal includes optional anti-reflection coatings proximate to the input and output face. A broadband high reflection coating is proximate to the input face for reflection of all radiation from approximately 0.68 to at least out to 1.5 micrometers wavelength. Light exiting from the output face of the crystal results from a photorefractive process that includes a transmitted beam and beam fan. The beam fan is fanned out of the optical path in a direction determined by the c-axis, dominant electro-optic coefficient, and charge carriers participating in the photorefractive process. The transmitted beam contains only incoherent radiation as input to a sensitive detector resulting in broadband multiline protection from the visible spectrum for substantially all pulsewidths and cw lasers, with enhanced time response and interaction length.

摘要： An optical material having an index of refraction dependent on wavelength of incident radiation is used between the reflectors of an off-normal Fabry-Perot cavity used as an interference filter. External to the cavity, and in the direction of incident radiation, another optical material having an index of refraction dependent on wavelength of radiation is placed. The incident radiation is thus refracted into and within the cavity dependent on its wavelength. By proper choice of the indices of refraction, and other variables, the filter may be designed to exactly match the output spectrum of a line spectrum laser, and to transmit all spectral lines of the laser, but to reflect all other radiation of interest.
