Abstract: A pixel sensor having a main photodetector and a parasitic photodiode and a method for reading out that pixel sensor are disclosed. The pixel sensor is read by reading a first potential on a floating diffusion node in the pixel sensor while the floating diffusion node is isolated from the main photodiode. The pixel sensor is then exposed to light such that the floating diffusion node and the photodetector are both exposed to the light. A second potential on the floating diffusion node is then readout while the floating diffusion node is isolated from the main photodiode. After the first and second potentials are readout, a third potential on the floating diffusion node is readout. The main photodiode is then connected to the floating diffusion node, and a fourth potential on the floating diffusion node is readout. First and second light intensities are determined from the readout potentials.

Abstract: LTCC coupled stripline resonator filters for use as bandpass filters are implemented with combline topology or with interdigital topology. The filter bandwidths range from about 0.3 GHz to about 4.5 GHz, or higher, depending of the manufacturing limitations with frequency operation of about 0.1 GHz to about 100 GHz. The filters have a plurality of through plated vias extending through the filters and connecting the top and bottom ground layers to form electric walls thereby reducing the coupling between the adjacent resonators.

Abstract: The present disclosure relates to a system and method utilizing a light source coupled with a viewing device to detect contaminant(s) on an electronic circuit board. This fluorescence microscopy apparatus can be easily integrated into a bench top stereoscope or microscope and does not require the use of expensive and destructive analytical techniques. Typically, blue light is used in conjunction with a filter to detect contamination from cured epoxy resins and many other contaminants on gold bond pads, wires, pads, or other electrically conductive elements on the electronic circuit.

Abstract: The invention measures the frequency of a heterodyne laser radar (LADAR) system signal in the input cell of a focal plane array (FPA). Embodiments amplify the return signal, and drive it into a counter for a fixed period of time. The frequency is the number of counts divided by the count time. An example design amplifier amplifies the return of a single photon response of an avalanche photodiode with a gain of 100 into a digital signal level at a 200 MHz rate with only 84 μW, demonstrating the feasibility of the approach.

Abstract: A fiber optic rotary joint includes a first fiber optic cable operably coupled to one of a stator and a rotor and a second fiber optic cable operably coupled to the other of the stator and the rotor. The stator and the rotor define a free space optical path between the first fiber optic cable and the second fiber optic cable. The rotor is rotatable about an axis of rotation parallel and collinear with an optical axis of at least one end of the fiber optic rotary joint. A first beam conditioning mechanism is configured to condition a light beam emitted from the first fiber optic cable and a second beam conditioning mechanism is configured to focus the conditioned light beam into the second fiber optic cable.

Abstract: A laser beam dump is provided. The laser beam dump may include a housing that has a plurality of connected walls defining an atypical or asymmetrical polygonal prism. When viewed in longitudinal cross-section, the asymmetrical polygonal prism housing defines a general hexagon shape. A chamber is defined by the housing and a highly reflective cone is positioned therein. The inner surfaces of the housing are formed from a highly absorptive material with respect to electromagnetic energy in the form of a laser beam. When an laser beam enters the chamber of the beam dump, it contacts the highly reflective cone outer surface and it nearly fully reflected to the absorptive walls of the housing. This reduces the reflection scatter of light from the first contact with the cone.

Abstract: The current disclosure is directed to a radar system. More particularly, the current disclosure relates to a fabrication of aperture-matched array of TEM horn antenna system and use of the same. Specifically, the current disclosure is directed to a compact and lightweight impulse radiating TEM array antenna system with high forward-to-back lobe ratio. Furthermore, the current TEM horn antenna system shows radiation efficiency close to 1 at the frequency bands between 150 and 250 MHz. More particularly, the current disclosure provides transverse electromagnetic (TEM) horn antenna including a curved surface extending arcuately at least 180° degrees from an antenna aperture opening defined at a signal-receiving forward end of a horn structure, wherein the curved surface is adapted to suppress large back-lobe properties.

Abstract: The system and method of integrated seed and high power pump source generates two wavelengths outside the effective gain bandwidth of a single gain medium without using two unique pump sources in a fiber amplifier train. The system and method uses a single pump power oscillator that passes a seed wavelength with no loss and minimal amplification to pump integrated amplifiers in both directions (forward and backward) resulting in amplification of the seed wavelength.

Abstract: Techniques for tracking a straight line object by creating a detection envelope between two detections selected from temporally-discontinuous frames are discussed. The detections within the detection envelope can then be analyzed in order to determine whether they are associated with a straight line track between the outer detections of the envelope. Techniques for identifying a launch-flash are also discussed. Potential launch flashes are checked for energy duration, intensity and spectral ratio. Techniques for detecting a hostile fire based on a single-frame detection are additionally detected. Based on a frame length of the detection, it can be determined whether the detection correlates to a hostile fire.
