Abstract: A system for characterizing miniature optical sources such as laser diodes is disclosed. In its most convenient form the system includes an optical system for collecting a wide angle beam and collimating the beam into substantially parallel rays. In the substantially parallel beam, equal area angular portions of the wide angle beam should correspond to equal areas in the parallel beam. Optical sensors are utilized to generate signals indicative of the intensity of the parallel optical beam. Digital processing is included to calculate the characteristics of the optical beam from the intensity samples of the parallel beam. In one embodiment, a reflecting plane is positioned between the source and the optical system so that Lloyd's fringes are produced in a measurement plane.

Abstract: A device for providing a substantially flat light field to a light imaging medium includes a transparent disc and an optical system. The surface of the disc is made opaque and light is coupled to the optical system through the edge of the disc by reflection from the internal surface of the disc. The intensity of light passing through the disc to the optical system decreases as the distance from the coupling edge increases. The combined effects of the disc and the optical system result in a substantially flat light field.

Abstract: A sensor may detect glare from a recorded image and a shade position of a motorized window treatment may be controlled based on the position of the detected glare in the image. A luminance of a pixel may be calculated in an image and a glare condition may be detected based on the luminance of the pixel. For example, the sensor may start at a first pixel in a bottom row of pixels and step through each of the pixels on the bottom row before moving to a next row of pixels. When the sensor detects a glare condition, the sensor may cease processing the remaining pixels of the image. The sensor may calculate a background luminance of the image by reordering the pixels of the image from darkest to lightest and calculating the luminance of a pixel that is a predetermined percentage from the darkest pixel.

Abstract: An optical sensor includes pixels. Each pixel has a photodetector. A readout circuit performs a process over an exposure time where the photodetector is connected to a reverse bias voltage supply to reset a voltage across the photodetector, and the photodetector is disconnected from the reverse bias voltage supply until that the voltage across the photodetector decreases in response to received ambient light. An ambient light level is then determine an based on a number of times the voltage across the photodetector is reset over the exposure time.
