Abstract: Optical apparatus (48) includes the holographic optical element (16) which diffracts the incoming ray (15) in a diffuse cone toward a viewing pupil and at an angle parallel to the axis of fiber optic faceplate (48) so the central ray (17) of the diffused cone passes through optical fiber (54) toward the viewing pupil. This permits the zero-order undiffracted light in ray (25) to be absorbed in the fiber optic faceplate (48).

Abstract: A portable 3-D scanning system collects 2-D profile data of objects (101) using a combination of a laser stripe positioning device and a video camera which detects the images of the laser stripe reflected from the object. The scanning system includes a laser stripe generator (1602), a video camera (1604), a scanning mirror (1601) attached to a continuously rotating motor (1603), an encoder or photodiode (1701, 1801, 1901) operationally coupled to the motor and associated electronics. As the scanning mirror reflects the laser stripe and positions it across the object, the encoder or photodiode generates signals indicating the angular position of the mirror. The video images of the reflected laser stripes and the angular positions of the laser stripes are synchronized by a computer to generate a 3-D model of the object.

Abstract: Optical systems are disclosed which are capable of generating and rapidly changing time delays of electrical signals for true time delay beam formation and beam steering and for signal processing applications. The systems utilize an interferometer configuration. A first optical modulator (12) in a first leg of the interferometer (14) is used to modulate coherent light with the signal to be delayed. In a second leg of the interferometer (26), a second optical modulator (28) provides beam steering to a prism stack (30), which produces a set of plane reference waves having a range of orientations required to generate a desired range of time delays. Preferably the optical modulators are acousto optic Bragg cells (12, 28). Alternatively, a stack of lens pairs of diffractive optical elements or a holographic optic element may be used in place of the prism stack. The modulated optical signal from the first leg interferes on an array of photodiodes with the reference waves from the second leg. The resulting electrical signals out of the photodiodes (20) are delayed replicas of the signals driving the optical modulator in the first leg.

Abstract: A method of writing plane holographic gratings Bragg-matched for reflection in the infrared in a photorefractive material using shorter wavelength light through a face perpendicular to the grating planes. The writing beam wavelength is selected to be within the photorefractive sensitivity range of the crystal and the angles are chosen relative to the wavelength to define a reflection grating with a period such that counter-propagating reflection occurs at the desired IR wavelength. For reflection gratings at different wavelengths, either the transmission or the reflection mode geometry may be used. In the transmission mode, the writing beams are incident on the same side face while in the reflection made the writing is on opposite faces in an off-axis (non-counter-propagating) configuration. Anti-reflection coatings of the appropriate wavelengths are used on the crystal surfaces to reduce reflection losses and improve the diffraction efficiency of the grating.

Abstract translation: 一种写入平面全息光栅的方法，使用较短波长的光通过垂直于光栅平面的面，在光折射材料中的红外中反射布拉格匹配。 写入光束波长选择在晶体的光折射灵敏度范围内，并且相对于波长选择角度以限定具有使得在所需IR波长处发生反向传播反射的周期的反射光栅。 对于不同波长的反射光栅，可以使用透射或反射模式几何形状。 在透射模式中，写入光束入射在相同的侧面上，而在反射中使写入在离轴（非反向传播）结构中位于相对面上。 在晶体表面上使用适当波长的抗反射涂层，以减少反射损耗并提高光栅的衍射效率。
