    Abstract: An indicator testing system for testing a plurality of indicators disposed on an electronic product and adapted to display a status includes a plurality of light sensors, a holder for holding the light sensors, and a signal processing module. The light sensors correspond in position to the indicators on the electronic product, respectively, and each generate a corresponding light testing signal whereby the signal processing module generates a brightness testing signal related to each indicator. The indicator testing system speeds up an indicator test, enhances the precision of the indicator test, and ensures the quality of the electronic product.

    Abstract: A reflective optical sensor includes a light emitting element to irradiate a target object with a light beam, a light receiving element to receive the light beam reflected by the surface of the target object, a circuit board on which the light emitting element and light receiving element are mounted, a cover element supported on the circuit board to surround the light emitting element and light receiving element, and a light shielding wall provided in the cover element to be a partition between the light emitting element and light receiving element to prevent a part of the light beam from the light emitting element from leaking to the light receiving element. A layer in a certain thickness is formed on the surface of the circuit board along either or both sides of the light shielding wall.

    Abstract: Described herein is an improved sensing system (30) and its method of operation. The system (30) includes a camera (16) for viewing an external scene, the camera comprising one or more detector(s) and has a field of view (40) which overlaps with the path (32) of a pulsed laser (12). The laser path (32) and radiation from the scene viewed (40) share a beamsplitter (36) and a window (38). In order to substantially reduce back-scattered radiation from the laser path (32) affecting operation of the detector(s) of the camera (16), the detector(s) is (are) switched in accordance with the operation of the laser (12) to be “off” or non-receiving when the laser (12) is “on” or firing.

    Abstract: Provided is a photodetection device which is small in size and has excellent sensitivity. The photodetection device (10) puts cathode terminals of photodiodes (1 and 2) having different spectral characteristics, or a photodiode (1) provided with an optical filter and a photodiode (2) provided with a light shield layer, into an open end state, and detects light intensity of a desired wavelength region according to a difference in electric charges that have been stored in those photodiodes in a given period of time. Since the photodiodes 1 and 2 store electric charges, even if a photocurrent is small, it is possible to store the photocurrent to obtain the electric charges required for detection, permitting achievement of downsizing and high detection performance of the semiconductor device on which the photodiodes 1 and 2 are formed. It is also possible to realize a wide dynamic range by making the electric charge storage time variable according to the light intensity, to suppress electric power consumption by intermittently driving an element required for differential detection at the time of differential detection, and to reduce an effect from flicker by averaging the output.

    Abstract: Disclosed is a low-cost high-resolution compact accelerometer which utilizes multiple self-mixing optical interferometers. The device is also a micro-opto-electro-mechanical systems (MOEMS) sensor. The interferometers are used to detect acceleration as well as monitor the wavelength, temperature, and refractive index and perform differential measurements.
