Abstract: Avoiding an illumination light irregularity to the utmost under increasing degree of integration and the memory capacity by suppressing a light amount irregularity on the illumination pupil plane to the utmost, unable to be adjusted by a conventional method. When the light amount irregularity on the illumination pupil plane which is the exit surface of the optical fiber is relatively large, focus of the imaging surface of the CCD camera is switched from the sample to the illumination pupil plane by a focus switching lens. The light amount irregularity is calculated and analyzed by the image processor. Based on the analyzed result, the exit surface position of the optical fiber is adjusted in the illumination optical system. In this manner, the illumination pupil plane which is the exit surface of the optical fiber can be adjusted to an illumination pupil plane where the light amount irregularity is small.

Abstract: A system and method for detecting radiation indicative of fire, such as forest fire. In one embodiment, a threshold energy level is determined based on ambient sensor conditions. A sensor unit may be setup to scan a predetermined area for electromagnetic radiation. Any detected electromagnetic radiation may then be band pass filtered to a wavelength range centered about a predetermined frequency associated with the presence of fire. The resulting energy level signal may then be further filter to pass only those signals which exhibit a “flicker” frequency. If the resulting filtered signal exceeds the threshold signal, a fire notification signal may then be generated.

Abstract: A vehicle light sensor for controlling light responsive systems such as an automatic headlamp dimmer. The sensor includes an enclosure containing a lens and a photo responsive detector. An optical chamber within the enclosure permits unwanted light from reaching the detector. A series of baffles within the chamber prevent light from outside a desired entrance angle from reaching the detector. A thin-film aperture is attached to the detector for controlling the size and shape of the detector's field of view. Gray scale shading may also be incorporated into the aperture to reduce the intensity of incoming light in selected portions of the field of view. An adjustment mechanism provides very fine angular view adjustments, beyond what is practical by simple assembly of molded parts.

Abstract: A light collector includes a light sampler for gathering light and a light receiver for receiving the light gathered by the sampler and for transmitting it to a system such as a light illumination control system. The output of the light collector varies with the intensity of the light gathered by the light sampler and can be increased or decreased for a given gathered light intensity by adjusting the distance between the light sampler and light receiver. Accordingly, if the light collector is used to provide to a light illumination control system the actual light intensity of the area in which light illumination is controlled, the light intensity maintained by the control system can be adjusted by increasing or decreasing the output of the collector. Also, the present invention includes a light gathering device for a light collector. The light gathering device includes a lens having angled portions for gathering light from a broad area.

Abstract: The present disclosure relates to limitation of noise on light detectors using an aperture. One example embodiment includes a system. The system includes a lens disposed relative to a scene and configured to focus light from the scene onto a focal plane. The system also includes an aperture defined within an opaque material disposed at the focal plane of the lens. The aperture has a cross-sectional area. In addition, the system includes an array of light detectors disposed on a side of the focal plane opposite the lens and configured to intercept and detect diverging light focused by the lens and transmitted through the aperture. A cross-sectional area of the array of light detectors that intercepts the diverging light is greater than the cross-sectional area of the aperture.

Abstract: A device is disclosed for monitoring power from a laser diode. The device includes a substrate having a top surface and a first facet perpendicular to the top surface through which light enters the substrate. The device further includes a second facet onto which light that has entered the substrate through the first facet along an optical axis that is non-normal to the first facet is incident. The device further includes a photodiode fabricated on the top surface of the substrate for measuring an intensity of the light that enters the first facet of the substrate along the optical axis that is non-normal to the first facet. The light that has entered the substrate through the first facet along the optical axis that is non-normal to the first facet is reflected by the second facet toward a photoactive region of the photodiode.
