Abstract: Holographic optical elements relatively free of unwanted, secondary fringes are produced using light having a limited coherence. A photosensitive material of a predetermined thickness records the interference between two beams of light. The mutual coherence of the two illumination beams is sufficiently great to form high contrast interference fringes within some portion of the photosensitive medium. The mutual coherence is limited to prevent the formation of high contrast interference with reflections from the various parts of the construction optics. The two illumination beams may be incident from opposite sides of the photosensitive medium forming a reflection holographic optical element or from the same side of the photosensitive medium forming a transmission holographic optical element. A laser generates the first illumination beam. Control of the mutual coherence may be by passing the first illumination beam through a moving diffuser plate or by varying the wavelength of the laser during the exposure. The second illumination beam may be formed by a reflector in contact with the photosensitive medium or by a beam splitter.

Abstract: An on-axis thick phase holographic optical element for use as a lens is fabricated by incorporating two off-axis holograms of two point sources located on opposite sides of the plate made by use of reference beams having a common angle with respect to the photographic media and complementary curvatures in the two cases. The element may be formed either by forming the two holograms in a single photographic emulsion, incoherently relative to one another, using a double exposure technique, or by forming the holograms on two physically separated media and then joining them to one another with their emulsion sides in contact. The resultant elements enjoy the low dispersion and aberrations like a conventional on-axis thin holographic optical element and the high diffraction efficiency like a thick hologram and additionally provide an extremely high ratio of diffracted to undiffracted light energy in the on-axis image.

Abstract: The present invention is a technique for construction of a laser protection window providing broadened angular protection. Plural modulated index of refraction filter elements are constructed to reflect incident light at a predetermined laser threat wavelength over a cone of protection. The plurality of modulated index of refraction filter elements are disposed in tandem at angles to a direction of primary view through the laser protection window which are symmetrical with respect to the direction of primary view. In a first embodiment, a first optional modulated index of refraction filter element is disposed perpendicular to the direction of primary view; the other modulated index of refraction filter elements are disposed in pairs at opposing angles to the direction of primary view. In an alternative embodiment, the angled modulated index of refraction filter element plates are formed of angled segments. The plural modulated index of refraction filter elements may be angled in two planes to provide extended angular coverage both horizontally and vertically.

Abstract: Holographic optical elements relatively free of unwanted, secondary fringes are produced by passing the light beam from a laser through a rotating diffusing plate to generate a beam of light having a very limited coherence length and a spatial coherence which changes over a period of time. A photographic emulsion having a mirror supported on its reverse side is illuminated by the beam and interference occurs between this primary illumination and illumination reflected from the mirror, creating fringes. No other interference fringes are formed because of the lack of coherence between secondary reflections and other rays of the incident beam. The rotation of the diffusion plate time averages out speckle patterns which would otherwise occur. Alternatively, the illuminating beam has a high degree of spatial coherence but its temporal coherence is reduced and varied over a period of time by changing the wavelength of a tunable-dye laser. Alternatively to use of the mirror technique the reduced coherence length beam may be divided into two sections which both illuminate the media at an angle after passing through precisely the same path length so that they interfere within the narrow coherence length of the light beams.

Abstract translation: 通过使来自激光的光束通过旋转扩散板来产生相对不含有不需要的二次条纹的全息光学元件，以产生具有非常有限的相干长度和在一段时间内变化的空间相干性的光束。 具有支撑在其反面上的反射镜的照相乳剂由光束照射，并且在该主要照明和从反射镜反射的照明之间产生干涉，产生条纹。 由于入射光束的次级反射和其他射线之间缺乏相干性，不会形成其他干涉条纹。 扩散板时间的旋转平均了否则会发生的斑点图案。 或者，照明光束具有高度的空间相干性，但是通过改变可调染料激光器的波长，其时间相干性在一段时间内减少和变化。 作为使用镜面技术的替代方案，减小的相干长度光束可以被分成两部分，两部分在通过精确相同的光路长度之后以一定角度照射介质，使得它们在光束的窄相干长度内干涉。

Abstract: An improved head-mounted optical illuminator or magnifier of the type worn by a medical or dental professional includes an optical coating applied to one or more optical surfaces associated with the illuminator or magnifier, and wherein the optical coating is a rejection coating operative to blocks wavelengths in the green, blue, violet and/or ultraviolet portions of the electromagnetic spectrum, depending upon the embodiment. Short-wavelength coatings (blue/violet/uv) may be applied to the surface of a lens used in a head-worn illuminator, for example to the beam-forming optics. The head-worn illuminator may be an LED illuminator, xenon illuminator, or other high-intensity source. In the case of the green notch filter coatings, these would typically only be applied to a head-worn magnifier, including flip-up and through-the-lens styles. In all embodiments, the optical coating may be a multilayer dielectric coating, a holographic filter, or utilize other optical filter technology.
