Abstract: A miniature, battery operated plastic module designed to project at least three different frequencies of energy from light emitting diodes is described. A first frequency is between 390 nm-420 nm just above harmful Ultraviolet Frequencies, a second frequency is between 850 nm-1200 nm in the infrared band and a third frequency is for a visible white light. The light emitting module has a base unit, the unit including a pulsed LED that emits an ultraviolet wavelength of light adapted to focus on a surface having phosphorescence means on the surface to activate the phosphorescence. The light emitting module may also have a base unit which includes a pulsed LED that emits an infrared wavelength of light adapted to penetrate a particular atmosphere. The module may also provide optional power for external items in addition to the three frequencies.

Abstract: This invention provides a solar simulator measurement method capable of high-accuracy measurements with fast-response photovoltaic devices as well as with slow-response photovoltaic devices, and a solar simulator for implementing the method. A flash having a pulse waveform with a flattened peak is generated from a xenon lamp. The flash is sensed by an irradiance detector, its irradiance measured, and the irradiance of the light source is adjusted to fall within a prescribed narrow range based on the detected irradiance value. Then, the flash with irradiance within the prescribed range irradiates photovoltaic devices under measurement, and the current and the voltage output by the photovoltaic devices are measured at multiple points while a load of the photovoltaic devices is controlled. This process is repeated with multiple flashes to obtain an I-V curve for the photovoltaic devices.

Abstract: A hollow sphere with a scattering (e.g., white diffusive) interior surface directs light input from at least one input light source to an exit. In one embodiment, an internal hot mirror and phosphor are positioned to intercept the input light on which visible light is reflected and ultraviolet light is directed to the phosphor for conversion to visible light. The exit has a reflective polarizer that passes light of a selected polarization to an output. Light of other polarization(s) is reflected back into the sphere where it becomes unpolarized because of reflections and may eventually be returned to the exit at the selected polarization.

Abstract: A method and system for characterizing and quantifying various error and calibration components of signals associated with photo-detectors. By varying the detector operational parameters such as input light intensity and integration times, measured signals can be analyzed to separate out and quantify various components of the measured signals. The various components thus determined may be categorized according to their dependencies on the operational parameters. Such component characterization allows better understanding of the detector system and ways in which such system can be improved so as to yield an improved measurement result for which the detector is being utilized.

Abstract: A system 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: A machine and methods measure a characteristic of an optical signal incident upon a detector characterized by one or more dynamic response parameters. One method receives an output signal from the detector and compares that output signal and a computationally determined response of the detector to a known optical signal incident upon the detector. The response is based on said one or more dynamic parameters. The method determines the characteristic based on a relationship between the output signal and the computationally determined response. Another method observes an output signal from an optical detector detecting one or more optical signals, accesses a characteristic curve of detector response, compares the observed output signal to the characteristic curve, and calculates at least one characteristic of one or more optical signals based on a relationship of the observed output signal and the characteristic curve.
