摘要： A sensor for remotely detecting an object, the sensor comprising: a light source having a coherence length that is short relative to the distance between the sensor and the object; a splitter splitting the emitted light beam into an incident beam and a reference beam; a photorefractive crystal recording a hologram on interfering reception of the reference beam and of the reflected beam reflected by an object illuminated by the incident beam, and playing back the hologram in a diffracted beam that is re-emitted by the crystal by anisotropic diffraction under the effect of the reference beam; a detector recording information on receiving the diffracted beam; and a polarizing filter that eliminates the major fraction of the reflected beam as transmitted by the crystal on receiving the reflected beam; such that the detector receives only the diffracted beam from the crystal. Both the sensor and imaging systems incorporating the sensor enable measurements to be made through diffusing media.

摘要： An authenticity identifying film (10) has a reflective film (11) having a circularly polarized light selectivity to reflect at least only either of right-handed circularly polarized light and left-handed circularly polarized light of incident light to produce reflected light. The reflective film (11) is provided with a hologram forming part (11a). The hologram forming part (11a) reflects circularly polarized light of the same circular polarization as that of the reflected light in a direction different from that of the reflected light to form a holographic image. The reflected light reflected by the reflective film (11) and the holographic image formed by the hologram forming part (11a) are detected by detectors disposed at different positions, respectively.

摘要： A method of fabricating an optical element including a liquid crystal layer having a spatially-varying tilt angle includes coating a substrate with a linearly photopolymerizable polymer layer, irradiating the linearly photopolymerizable polymer layer with linearly polarized ultra-violet light at a oblique angle, and coating a layer of liquid crystal material on a surface of the irradiated linearly photopolymerizable polymer layer. The liquid crystal material has a predetermined relationship between its tilt angle and a total dose of the linearly polarized ultra-violet light. The linearly photopolymerizable polymer layer is irradiated with at least one dose of linearly polarized ultra-violet light that is sufficient to induce formation of a plurality of discrete regions within the liquid crystal layer having a larger in-plane birefringence than an adjacent or surrounding region.
