Abstract: An apparatus for testing transmission of a lens includes a light source, a focusing device, an integrating sphere, a moveable carrier, a detector, and a processor. Light, in a specific wavelength range, is emitted from the light source. The focusing device is configured for collimating and focusing the light to transmit the light onto the lens being tested. The integrating sphere is configured for receiving light transmitted through the lens. The moveable carrier is configured for facilitating a relative movement between the lens and the integrating sphere. The detector includes a light sensor configured for detecting a light intensity received by the integrating sphere and transforming the light intensity into a comparing signal for comparison. The processor is configured for comparing a signal of the intensity of the light transmitted to the lens with the comparing signal to obtain a transmission efficiency/percentage of the lens.

Abstract: A method for calibrating a sensor in a vehicle, such as a space capsule or other space borne apparatus, uses an expandable integrating sphere. A sensor in the vehicle measures the energy from an electromagnetic energy source within the integrating sphere through a calibration window. The expandable fluid impermeable integrating sphere expands when filled with a fluid, such that when filled with the fluid, its interior is viewable through the calibration window. The system includes a source of fluid to fill the integrating sphere and a fluid regulator coupled to the vehicle to determine when to supply the fluid to the integrating sphere to maintain an appropriate gas pressure level with the integrating sphere.

Abstract: The invention concerns a method and device to carry out the method to provide quality control for a photosensor, especially a photodiode array, whose output signal depends on the intensity of an input signal formed by electromagnetic waves. The photosensor to be tested receives stimulation signals forming the input signals while the stimulation signal intensity of the stimulation signals is varied. The associated output signals of the photosensor to be tested are measured and recorded for evaluation purposes. The photosensor preferably receives at least two independently controllable, superposed individual stimulation signals with individual intensities. The different stimulation signal intensities of the individual stimulation signals are set with the aid of a controller coupled to stimulation signal source, and the output signals of the photosensor are measured and recorded using a measurement data recorder unit.

Abstract: A remote laser sensor incorporating a single integrated detector. The laser sensor comprises a laser for transmitting laser energy that is applied to a target, and a beamsplitter for sampling of the transmitted laser energy. A telescope is provided for collecting laser energy reflected from the target. The integrated detector comprises an integrating sphere for receiving the sampled transmitted laser energy and for receiving the laser energy reflected from the target, and a detector coupled to the integrating sphere for selectively detecting the sampled transmitted laser energy and the laser energy reflected from the target. A scatter plate may be disposed inside the integrating sphere for preventing photons from entering the detector that result directly from a first scattering event within the sphere. In operation, the laser provides a transmit beam that is directed at the target and reflected energy from the target is collected by the telescope and focused onto the detector. Detector integration is accomplished by using a single detector chip mounted to a rear surface of the integrating sphere, which allows sampling of the entire cross-section of the laser transmit beam. The beamsplitter is employed to sample a portion of the transmit beam which is applied to the detector.

Abstract: A test arrangement for assessing the spectral energy distribution-determined response of a night vision device or other electro-optical apparatus. The test arrangement provides a library of spectral energy-distributed test signals or input scenes which may be selected to represent for example typical or extreme conditions expected during field use of the tested night vision device. The test signals originate in an array of energy transducer devices such as light emitting diode elements with each such light emitting diode element proving a limited wavelength component of the wide band composite optical signal received at the input port of the night vision device. Each component signal is arranged to be controlled electrically in presence or absence and also controlled electrically in radiance or intensity according to the needs of the scene being presented; such control is provided by a manual controller or by a programmed digital computer or by other controlling apparatus such as a programmed logic array. The composite test signal may include both infrared and visible components. In addition to control of the composite test signal, other aspects of the performed test such as test scene data storage may also be accomplished in the controller or computer. The disclosed apparatus is especially suited to performance verification of night vision systems in a laboratory environment prior to field use of similar systems. Military and non-military uses are contemplated.
