Abstract: A method of detecting objects with a night vision system is provided. The night vision system includes a light source and a camera. The method includes activating the light source as a sequence of light pulses wherein each light pulse is increasing in intensity for a predetermined number of pulses to form a pulse train. The camera is activated as a corresponding sequence of detection windows wherein each of the windows corresponds to one of the light pulses for receiving reflected light resulting from the corresponding light pulse. The light pulses and detection windows are configured such that a time delay between each corresponding light pulse and detection window is increasing throughout the pulse train. In another variation, the camera gain is increased throughout the pulse train. In yet another variation, the light pulses have constant amplitude, the camera gain is constant for all pulses, and the number of camera gain windows increases as the delay increases. In all cases, objects nearer the night vision system are imaged with lower intensity light, less camera gain, and/or fewer laser pulses than objects further away to provide a composite image in which the apparent brightness of near and far objects can be controlled.

Abstract: The invention describes systems and methods for calibrating a low-level light imaging system. Techniques described herein employ a light calibration device that is placed within a low level light imaging box to calibrate the system and its constituent components such as the camera and processing system. The calibration device comprises an array of low-power light supplies each having a known emission. By taking an image of each low-power light supply, and comparing the processed result with the known emission, the accuracy of the imaging system and its absolute imaging characteristics may be assessed and verified.

Abstract: The invention describes systems and methods to obtain and present imaging data in absolute units. The systems and methods convert relative image data produced by a camera to absolute light intensity data using a compensation factor. The compensation factor accommodates for hardware and specific imaging conditions in the imaging system that variably affect camera output. The present invention determines the compensation factor based on assessing the output of the camera against a known light source for a specific set of imaging conditions in the imaging system. The compensation factor is then stored in memory corresponding to the specific set of imaging conditions. Upon subsequent imaging with the set of imaging conditions, the corresponding compensation factor is called from memory and applied to the camera output. A compensation factor may be determined and stored for each hardware state and imaging condition available to the imaging system.

Abstract: A modulated infrared source is disclosed in which spatial-on-spatial modulation is accomplished by the rotation of two sets of beam forming optics about an infrared source. Close to 100% of the energy from the infrared source is focused by rotating two sets of parabolically shaped mirrors about the IR source such that energy losses due toe modulation technique are minimized. The speed of the rotation of the reflective optics is minimized while maintaining sufficiently high modulation frequencies the initial provision of four beams from a single source. This is accomplished by the first set of beam forming optics. Moreover, the effects of unwanted reflection are minimized by the four beam configuration. The four beams are then themselves modulated by the second set of beam forming optics.

Abstract: A generator of energy-depleted radiation and various methods and applications using the energy-depleted radiation. Various embodiments are disclosed of the energy-depleted radiation generator and an energy-restored radiation generator, which permits detection of wave properties of the radiation without regard to the depletion of its energy. The energy-depleted radiation generator functions in one embodiment by selective transmission of destructively interfering radiation. Other embodiments use two-beam coupling or directional coupling to achieve energy depletion. Restoring energy to an energy-depleted radiation beam is accomplished by transferring energy to it from a reference beam, in a beam-to-beam transfer or in an optical amplifier. The invention has important applications in fields such as communications, specimen analysis, photorefractive recording, holography, and other fields in which the reduction of energy content in the associated radiation is advantageous.

Abstract: A wavelength shifting filter having two sheets of material adjacent and parallel with a spacer therebetween about the periphery of the sheets. The sheets are held in a frame. A phosphor coating is located on the inner side of one of the sheets. A transilluminator is associated with the filter and provides radiation in the UV wavelength. One sheet of the filter transmits the UV wavelength. The other sheet transmits at least a portion of the wavelength that the phosphor coating generates when subjected to the UV radiation of the transilluminator. The visual effect of white light is enhanced by the use of white glass.

Abstract: A calibration system for a measuring device utilizing a photo multiplier tube is provided. The calibration system is intended to provide a stable light source variable over a wide range of intensities which can be used to calibrate the PMT reading using a closed loop feedback circuit. The LED and a photo cell are disposed in a reference block chamber whereby the photo cell is in close proximity disposed perpendicular to the axis of the LED. The LED being dome shaped will direct light energy on to the photo cell, and also peripherally. The PMT is disposed adjacent the LED and at an angle to its longitudinal axis whereby light generated by the PMT simultaneously strikes both the photo cell and the PMT without reflection.
