20140247365 | TECHNIQUES FOR SELECTIVE NOISE REDUCTION AND IMAGING SYSTEM CHARACTERIZATION - Various techniques are disclosed for reducing spatial and temporal noise in captured images. In one example, temporal noise may be filtered while still retaining temporal responsivity in filtered images to allow low contrast temporal events to be captured. Spatial and temporal noise filters may be selectively weighted to more strongly favor filtering using whichever one of the filters is least likely to cause a loss of signal fidelity in actual scene content. Other techniques are disclosed for determining various parameters of imaging systems having image lag. For example, a mean-variance characterization and a noise equivalent irradiance characterization may be performed to determine parameters of the imaging systems. Results of such characterizations may be used to determine the actual performance of the imaging systems without the effects of image lag. | 09-04-2014 |

20150054964 | COMPACT THERMAL AIMING SIGHT - A sight attachable to a weapon and comprising an objective lens, an image display, and a digital reticle. The objective lens focuses infrared light received from a scene onto a thermal imager, which is comprised of a focal plane array that detects infrared radiation in the scene focused by the lens. The image display is in signal communication with the thermal imager and provides an image of the received infrared light from the scene. The image rendered by the display is visible to the user. The digital reticle is rendered on the display and provides an aim point of the weapon upon a target in the scene. The image of the scene and superimposed reticle are directly viewable by a user with the aim point of the weapon upon the target being maintained constant over a range of viewing angles that depart from a viewing angle perpendicular to the display. | 02-26-2015 |

For example, according to one or more embodiments, switchable interconnects may be implemented within the FPA, wherein the switchable interconnects comprise a plurality of switches adapted to selectively connect or disconnect infrared sensors of the FPA to/from column lines, row lines, and between each other. The switchable interconnects may also comprise another set of switches adapted to selectively connect adjacent column lines together. By selectively opening and closing appropriate switches of the switchable interconnects, two or more neighboring infrared sensors may be binned together to form a binned detector. Advantageously, the binned detector, along with the array and associated circuitry, may provide increased sensitivity, reduced power consumption, and/or increased frame rate. | 11-05-2015 |
20150362371 | EXTENDED TEMPERATURE MAPPING PROCESS OF A FURNACE ENCLOSURE WITH MULTI-SPECTRAL IMAGE-CAPTURING DEVICE - A process is provided for mapping temperatures in an enclosure. A spectral band for a multi-spectral image-capturing device is selected. An intensity-temperature mapping is generated by performing an intensity-temperature calibration based on an intensity of an image pixel in a field of view (FOV) generated by the multi-spectral image-capturing device, a corresponding temperature measurement, and a selected device setting of the image-capturing device. An emitted radiation is detected based on a first spectral image in the FOV. At least one region is determined whether it is poor responsive, which is underexposed or overexposed, such that an accurate temperature is unable to be estimated based on a temperature value associated with the spectral band. Temperatures of the at least one poor responsive regions are replaced with temperatures from corresponding acceptable regions from at least one other spectral image to provide an extended temperature mapping of the enclosure. | 12-17-2015 |
