Abstract: A device for measuring the intensity of incoming light is disclosed. This device includes a rotatable light blocking unit which interrupts incident signal light at short regular intervals. The device also includes a light source which emits certain light different from the signal light while the signal light is interrupted by the block unit, and a measurement unit for measuring intensity values of the signal light and the certain light. A correction unit is provided for correcting the measured signal light intensity based on the certain light intensity. A calculator unit calculates a correction value through comparison of the intensity of the certain light to a reference value. The correction unit uses this correction value to correct the signal light intensity.

Abstract: A sensitive photon detection system generates an electronic photon sensor signal as a K factor times a number N photons per unit time. The system is configured by combining a separate optical amplifier with a gain factor K1 with a photo detector with a gain factor K2 such that K may be realized as the product of K1 and K2. The values of K1 and K2 are chosen to meet a predetermined K while optimizing a signal quality of the photon sensor signal. The optical amplifier may be preceded by a photon gathering device and/or a light chopping device to further optimize system performance. Further, the photon sensor signal may be further processed analog circuitry or may be digitized and processed using digital signal processing to generate an enhanced photon sensor signal with enhanced signal quality by adding gain and/or bandwidth limiting.

Abstract: A laser countermeasure system uses a fluence trigger along an optical path between an entrance and a detector at an output. The fluence trigger detects laser radiation and blocks the passage thereof beyond the trigger. A shutter at the front end can be operated in response to detection by the trigger. A threat analyzer also receives radiation and automatically breaks the radiation into spectral components for correlation to appropriate filters to remove the harmful coherent radiation. A tunable filter and/or a filter wheel is interposed along the optical path and is controlled by an adjustment system, illustratively servo controls. The adjustment system responds to the threat analyzer to select and interpose automatically the proper filter(s) to attenuate or block the coherent radiation. Thereafter, the fluence trigger and/or shutter operate to restore full operation along the optical path. The system and method provide look-through capability and mission continuity in the face of unknown laser threats.

Abstract: The invention is a pneumatically actuated energy collection device. The device includes a support which has an energy collector thereon. A shutter is slidably attached to the support and can be moved between a first nullclosednull position and a second nullopennull position. In its first position, the shutter covers the collector and in its second position, the shutter uncovers the collector. The shutter is biased into one of the positions. A chamber is disposed adjacent to the shutter so that when the chamber is pressurized, the shutter bias is overcome and the shutter is moved between the first position and the second position.

Abstract: A pyroelectric detector is provided to measure the energy of pulsed light. To measure the power of continuous wave light (CW light), the pyroelectric detector is releasably attached to optical sampling apparatus which divides the CW light into pulsed light. Means are included to inform processor circuitry in the read-out electronics that the detector is attached to the optical chopper. The processor circuitry then calculates the power of the CW light given the energy of the pulsed light by the pyroelectric detector and the exposure time which is fixed by a crystal clock.
