Abstract: A method and an apparatus for measuring viewing-angle dependent luminance (luminance characteristic) of an LCD panel by condensing radiation from LCD pixels by means of a condensing device which includes a mirror, and by forming a real image of the pixels on an CCD imaging device. Correct luminance characteristic of the LCD panel is calculated by making a correction of the data thus obtained using a predetermined condensing function. The correction removes blurring of data due to condensing effect of the condensing device, thereby preventing degradation of the resolution of the angular luminance measurement apparatus. The condensing device and the CCD imaging device are moved depending on the viewing-angle of the pixels. When the intensity of light entering the condensing device decreased by the move, the correction is performed.

Abstract: The present invention provides a wavelength dependent compensation method in a variable optical attenuator which can precisely set the amount of attenuation within a wide range of wavelengths, and to provide superior operability. An optical signal 20a is emitted from a white light source 20 incident on a monochromator 21, and under control of a CPU 24, only an optical signal 20b of a specific wavelength is extracted and is made incident on a variable optical attenuator 22; in optical attenuator 22 under control of a CPU 24, optical signal 20b is attenuated; the power of attenuated optical signal 20c is measured by power measurer 23 under control of a CPU 24, producing compensating data; and using the pulse number corresponding to the rotation angle of the motor which activates the variable optical attenuator 22 according to this compensating data, the position of variable optical attenuator 22 is compensated to attain the desired amount of attenuation.

Abstract: A method and apparatus for mounting an optical sensor in an optical instrument. The optical sensor is attached to a rigid substrate. The substrate has two locator holes, with the sensor mounted between the holes. Rigid locator pins attached to the housing of the instrument protrude into the locator holes. A spring pushing against the substrate forces the locator holes against corresponding locator pins, aligning the substrate within a plane. In a first embodiment, the holes are positioned so that the optical sensor is rigidly held at its midpoint, minimizing dimensional deviations along the length of the sensor with temperature change. The sensor assembly is easily removable and the mounting apparatus does not mechanically stress the substrate or the sensor with temperature changes. The mounting apparatus is easily manufactured, allows precise alignment, and is inexpensive.

Abstract: An optical detector calibrator system simulates a source of optical radiation to which a detector to be calibrated is responsive. A light source selected to emit radiation in a range of wavelengths corresponding to the spectral signature of the source is disposed within a housing containing a microprocessor for controlling the light source and other system elements. An adjustable iris and a multiple aperture filter wheel are provided for controlling the intensity of radiation emitted from the housing by the light source to adjust the simulated distance between the light source and the detector to be calibrated. The geared iris has an aperture whose size is adjustable by means of a first stepper motor controlled by the microprocessor. The multiple aperture filter wheel contains neutral density filters of different attenuation levels which are selectively positioned in the path of the emitted radiation by a second stepper motor that is also controlled by the microprocessor. An operator can select a number of detector tests including range, maximum and minimum sensitivity, and basic functionality. During the range test, the geared iris and filter wheel are repeatedly adjusted by the microprocessor as necessary to simulate an incrementally increasing simulated source distance. A light source calibration subsystem is incorporated in the system which insures that the intensity of the light source is maintained at a constant level over time.

Abstract: A photosensor arrangement produces an electrical signal responsive to the position of a source of light by employing a mask situated at a predetermined height above a plurality of photodetectors, such that as the sun moves with respect to the apparatus, a shadow is cast which is responsive to the location of the sun. An apparatus constructed in accordance with the invention has a plurality of photosensors, each having a respective substantially planar light-sensitive surface for receiving the input light from the sun over a predetermined range of positions. In a preferred embodiment where compactness is desired, the planar light-sensitive surfaces are arranged in a substantially coplanar relationship with respect to one another. The light mask, which has opaque and transparent portions, is arranged to overlie the substantially planar light-sensitive surfaces for determining the position-responsive sensitivity characteristic of the apparatus. In certain embodiments, a diffuser is interposed between the light mask and the photodetectors. The response characteristic of the apparatus can be determined by geometric analysis, or empirically using values which may be stored in a look-up table.
