Abstract:
A deuterium lamp box (50) is capable of emitting light, which is different from that emitted by a deuterium lamp (10), through an opening (69). Specifically, when the see-through deuterium lamp (10) is turned on, light is emitted from the deuterium lamp (10) through the opening (69). When the deuterium lamp (10) is turned off and a second lamp (85) is turned on instead, the light from the second lamp (85) is converged by a lens (84), passed through the deuterium lamp (10), and emitted through the opening (69). When the deuterium lamp (10) and the second lamp (85) are turned on simultaneously, light of mixed different wavelengths is emitted through the opening (69). Thus, three kinds of light can be produced using either of the lamps (10, 85) or both, and the lamp box is more versatile than the single-lamp box.
Abstract:
An apparatus which permits an analytical probe (1) to be calibrated by pressing the tip against a block of material (2) of controlled characteristics. A transparent elastomer is used into which has been incorporated a light scattering material. Elastomer calibrators (2) may also be made part of a preassembled probe component such as a disposable sheath (7). In that case the turbid elastomer (2) is assembled on the tip with the other components of the sheath (7) and is removed after calibrating the system and before the probe (1) is put into use. An additional film of flexible polymer (3) having optical characteristics analogous to the material to be detected by the probe (1) may be placed on top to simulate the structure of the material that is to be measured.

Abstract:
An apparatus includes a light source to transmit non-visible light pulses strobed at a frequency and a duty cycle. A detector a detector receives a pattern of reflected light from a display in response to the non-visible light pulses. The pattern of reflected light had at least two different polarization states, where the detector determines a spatial location of the detector relative to the display based on discriminating between the at least two polarization states.

Abstract:
A system for testing a photo-voltaic cell is provided with a holder for the photo-voltaic cell, with electrodes for receiving a signal from the cell. A light source system provides for light with a spectral composition of terrestrial sunlight. A spatial light modulator with a two dimensional array of controllable mirrors or other pixel modulators is used to form a spatial pattern of this light in an image area that comprises the surface of a photo- voltaic cell. In an embodiment a plurality of spatial modulators is used to modulate different parts of the light from the light source system, which have different light properties. One part may light with the spectral composition of terrestrial sunlight and an other part may overlap with the spectral composition of terrestrial sunlight only in a limited wavelength band for example. Thus a light pattern with different light properties in different areas can be realized without spatial or temporal multiplexing. A control system controls the spectral composition part of light and spatial modulation by the first and second spatial light modulator. Electric signals in response to the control light are captured from the photo-voltaic cell.
