    Abstract: A device for controlling an amount of light of a lighting unit for use in an endoscope, used to view an image of an object. The device includes a plurality of light shields for shielding light generated by a light source and transmitted to the endoscope. A plurality of stepping motors drive the light shield for a series of predetermined time intervals. Brightness of the image is detected during each of the time intervals and pulses are generated during each of the time intervals. The number of pulses generated is determined in accordance with a difference between the brightness of the image detected during each of the time intervals and a desired brightness of the image. The pulses generated are used to control the drive of the plurality of stepping motors in each of the plurality of time intervals.

    Abstract: An optical masking apparatus of an OTDR capable of lowering insertion loss and of easily aligning optical axes and of being structured at low cost. The apparatus comprises an optical pulse generating means, an optical branching coupler for permitting an optical pulse generated by the optical pulse generating means to be incident to an optical fiber to be measured, and an optical chopper means to which a reflected light from the optical fiber is incident by way of the optical branching coupler wherein the optical chopper means operates in synchronization with the optical pulse to remove a desired range of the reflected light. A light signal supplied to an optical/electric transducer from the optical chopper means is converted into an electric signal, which is displayed on an indicator by way of a signal processing circuit.

    Abstract: A high efficiency integrating sphere that can be used in a large variety of scientific instruments. The sphere having an efficiency gain obtained by using a superconducting material, acting as a perfect reflector, on the inside hollow surface of the sphere. The sphere is operated with a delay between the incident and sensed light, heretofore not possible, and yielding substantial improvement in the signal-to noise ratio of the integrating sphere.

    Abstract: Disclosed herein is a method comprising: sending radiation pulses (i), i=1, . . . , M one by one toward an object and toward an image sensor as the image sensor moves nonstop in a first direction with respect to the object; and for each value of i, capturing with the image sensor a partial image (i) of the object using radiation of the radiation pulse (i) that has transmitted through the object. The image sensor comprises N active areas. Each active area of the N active areas comprises multiple sensing elements. For each value of i, the radiation pulse (i) has a pulse duration during which the image sensor travels a distance shorter than a width measured in the first direction of any sensing element of the image sensor. M and N are integers greater than 1.

    Abstract: Techniques are provided to perform flat field correction for infrared cameras using a liquid shutter. Devices and methods provide a focal plane array (FPA) that receives infrared radiation (e.g., thermal infrared radiation) from a scene, and infrared-opaque liquid disposed in a cavity of a liquid shutter housing, and a fluid controller that directs the liquid from a reservoir area of the cavity to a field of view area of the cavity to block the FPA from the infrared radiation. Flat field correction terms may be determined and radiometric calibration may be performed. In one example, a liquid shutter uses voltages to direct liquid. In another example, a liquid shutter uses magnetic fields from electromagnets to direct liquid such as ferrofluid. In another example, a liquid shutter uses electrowetting techniques to direct liquid such as water. In a further example, a liquid shutter uses a pump.

    Abstract: A testing device for measuring the light characteristics of an electronic component includes an inlet at one end at which an electronic component can be presented for testing. A shutter is located at the inlet and is moveable between a first open position in which an electronic component can be received into the inlet, and a second closed position in which the shutter can overlay at least the majority of a nest on which said electronic component is supported, so that the shutter prevents light emitted by the electronic component from being diverted away from the testing device. The shutter includes at least one sliding door that can be slid to move the shutter into its first and second open positions. The at least one sliding door includes a cut out portion that defines said opening when the shutter is in its second closed position.
