摘要： An imaging method creates a two-dimensional image of a voltage distribution or a capacitance distribution across a surface of a substrate under test using an electro-optic modulator which is positioned and biased with respect to the surface of the substrate. The method involves a first coarse offsite calibrating step to compensate for nonuniformities in the light emerging from the modulator. Then, for each successive portion of the substrate over which the modulator is to detect characteristics of the substrate, the system undergoes a modulator relocating step, a modulator levelling step, a modulator gapping step, a fine onsite calibrating step, and a measuring step. An apparatus is disclosed for levelling the bottom surface of a modulator into a substantially coplanar spacial relationship with a portion of top surface of the underlying substrate being tested monitors light emerging from at least three regions on the top surface of the modulator in order to determine the relative distances of three corresponding regions of the bottom surface of the modulator from the underlying top surface of the substrate being tested. In one embodiment, three transducers are used to control the spacial orientation of the modulator. The method and apparatus see special application in detecting defects in LCD display panels.

摘要： Ultra Violet (UV) light produced by a light source is converted to visible light and utilized in a visible light output of the light source. The light source is, for example, a light source in an illuminator of a projection device. UV light that is typically filtered out of the illuminator is converted by a UV absorbing visible light radiating phosphor. The UV light is directed to the phosphor by, for example, reflecting the UV light out of a light path, concentrating the UV light via a concave reflector, and directing the UV light to the phosphor. The re-radiated visible light is then injected back into the light path of the light source. In one embodiment, the re-radiated visible light is injected into a “shadow” of the light path.

摘要： An absorptive layer is added to an image display system. The absorptive layer is selected to compensate for tint in a black state of a displayed image. In a Liquid Crystal On Silicon (LCOS) based light engine, blue wavelengths may cause a predominate tint in black portions of an image (or an entirely black image is tinted blue), and the absorptive layer is calculated to absorb an amount of blue equivalent to the tint. The absorptive layer is, for example, an unbalanced magenta dichroic, or a yellow filter. The yellow filter may be placed at any point in the light chain, including input/output of a kernel, input/output of a projection lens, or portions of a light engine or display screen. An unbalanced magenta may be constructed by adding a yellow filter to an existing magenta dichroic in the kernel design.

摘要： A laser beam attenuator and a method of attenuating a laser beam are disclosed. The laser beam attenuator includes first and second prisms, a beam dump, and a light absorbing body. An input laser beam partially refracts and partially reflects at a first surface of the first prism to form first refracted and reflected laser beams. The first reflected laser beam partially refracts and partially reflects at a second surface of the second prism to form second refracted and reflected laser beams. The beam dump and the light absorbing body absorb the first and second refracted laser beams. Thus, the second reflected laser beam forms an attenuated laser beam.

摘要： A phosphor layer is positioned to absorb UV light and re-radiate usable light in other wavelengths. The UV light is reflected to the phosphor by a thin film placed in a light path. The phosphor re-radiates the usable light in a direction of the light path. Curved mirrors or directive reflectors are utilized to direct some of the re-radiated light toward the light path. In one embodiment, usable light in the light path is reflected by a thin film, UV light is passed by the thin film toward the phosphor, and the re-radiated light is directed toward the reflected visible light path.

摘要： A compensated higher order waveplate is constructed of substrates. In one embodiment, a first substrate is a nλ waveplate and the second substrate is a (n+Δ)λ waveplate. The substrates are oriented so that their principle axes of retardation are orthogonal. nλ is a base retardation of a waveplate and Δλ is an incremental retardation. The incremental retardation produces a desired amount of retardation of a lightwave passing through the compensated higher order waveplate. Retarder material used to produce the base retardation is approximately ½ a desired thickness of the waveplate. Multiple waveplates are combined to produce any of wavelength band specific retarders and multiple non contiguous wavelength band specific retarders.
