Abstract: A hot spot filter for a light guide is created by taking an image of the light output pattern of an illuminated light guide. The hot spot filter may be a film, a layer, or an additional liquid crystal display dedicated to attenuating bright spots from the light guide. The hot spot filter may be incorporated into the image display by adjusting the grey scale of individual pixels to provide sufficient compensation.

Abstract: A sensor arrangement for determining brightness, comprising a photosensor and a reflector. The photosensor and the reflector are positioned such that light reflected by the reflector reaches the photosensor; and the reflector is designed such that a visible fraction of the ambient light is reflected, and an infrared fraction of the ambient light is transmitted. In this way, a sensor arrangement is created which is modeled on the perception of the human eye and which is comparatively easy and economical to produce.

Abstract: An optical beam profiler using a spatial light modulator and photodetector. In an embodiment, the spatial light modulator is a two-dimensional (2-D) small tilt digital micromirror device. The profiler features fast speed, digital controls, low polarization sensitivity, and high measurement repeatability. The 2-D multi-pixel device-based profiler allows the use of several beam profile measurement concepts including moving knife edge, scanning slit, moving pinhole, variable aperture, and 2-D photodiode array. The proposed digital optical beam profiler can be implemented with any type of digitally operated 2-D spatial light modulator device such as using liquid crystals, magneto-optics, multiple quantum wells, electro-optic polymers, and photonic crystals.

Abstract: Apparatus (10) for interrogating an optical signal (not shown) propagating in an optical waveguide, such as an optical fiber, having an input section (12) and a second section (14) through which light entering from the input section (12) will subsequently propagate. The second section (14) includes a grating portion, such as a tilted chirped fiber Bragg grating (16). The grating (16) causes at least part of the optical signal to be coupled out of the optical fiber, through the fiber cladding. A photodetector (18) is provided generally alongside the grating (16). The photodetector (18) is arranged to collect and detect substantially all of the outcoupled optical signal. The relationship between the optical power outcoupled by the grating (16) and the wavelength of the optical signal is known, allowing a measurement of the outcoupled optical power to be used to determine the wavelength of the optical signal propagating through the grating (16).

Abstract: A matched pair of tilted gratings may be formed in a section of optical fiber (or waveguide) and used as a “tap” to measure the power of an optical signal passing through the fiber. By using a pair of highly-tilted gratings (e.g., tilted at an angle of 45° with respect to the optical axis) and orienting the gratings to be orthogonal with respect to one another (i.e., azimuthal orthogonality around the fiber axis), a pair of orthogonally polarized beams will be out-coupled from the propagating signal. Since the pair of beams are orthogonal, their sum can be made insensitive to variations in polarization of the optical signal propagating along the fiber.
