  • Patent number: 10621702
    Abstract: A system reducing pixel-based spatial noise for an uncooled infrared imager includes a first step of subtracting the historical scene-based NUC offsets for each selected pixel calculated from the previous frame. A filtered image for output module output is calculated using an edge preserving smoothing filter. The edge preserving smoothing function consists of a plus-shaped median kernel in which selected pixels that differ from the center pixel by greater than a specified threshold are replaced with the center pixel. The result is subtracted from the center pixel forming a high pass, edge ignoring, version of the frame which is dominated by system noise. A low pass version of the noise frame is created with a 5×5 mean filter. This is subtracted from the initial noise frame to improve scene rejection. This high pass version of the image/noise frame is attenuated by a configurable value.

  • Patent number: 10531206
    Abstract: A processor comprises instructions to adjust a bias of an input signal in order to decrease a duty cycle of a pulse modulated optical signal. The bias can be increased, decreased, or maintained in response to one or more measured values of the signal. In many embodiments, a gain of the signal is adjusted with the bias in order to inhibit distortion. The bias can be adjusted slowly in order to inhibit audible noise, and the gain can be adjusted faster than the bias in order to inhibit clipping of the signal. In many embodiments, one or more of the bias or the gain is adjusted in response to a value of the signal traversing a threshold amount. The value may comprise a trough of the signal traversing the threshold.

  • Patent number: 10523883
    Abstract: A noise data update processing unit calculates the amount of a fixed pattern noise component on the basis of a detection signal of infrared rays detected by an infrared detector in a state where an optical system is controlled to be in a non-focused state, and updates an FPN data storage unit with the calculated amount of the FPN component. The noise data update processing unit calculates an average value of detection signals of each detector element and a plurality of peripheral detector elements, and calculates a signal component dependent on incident infrared rays included in the detection signal of each detector element by subtracting an average value of fixed pattern noise data before update from the calculated average value. The amount of the fixed pattern noise component is calculated by subtracting the calculated signal component from the detection signal of each detector element.

  • Patent number: 10520330
    Abstract: A mobile device and a method for estimation of direction of motion of a user are described. The mobile device comprises an inertial sensor to capture acceleration signals based on motion of the user and a direction estimation module. The direction estimation module determines direction of gravity based on filtering acceleration values obtained from captured the acceleration signals using a low-pass filter to identify a plane orthogonal to the direction of gravity. The plane orthogonal to the gravity comprises two orthogonal axes orthogonal to the direction of gravity. Further, displacement values are evaluated based on a user input for placement of the mobile device with respect to user's body, and integration of the acceleration values across the two orthogonal axes with respect to time. A direction of motion of the user is estimated based on a ratio of the displacement values along the two orthogonal axes.

  • Patent number: 10466044
    Abstract: The system and method of sensor imager and laser alignment. The system utilizes a DLP mirror array with a compact collimator to provide a real time, direct mapping of the laser energy from a LRF onto an imager (e.g., visible, SWIR, LWIR, or the like) by using a back scatter approach. This method eliminates the thermal and vibration/shock optical alignment issues by using a relative measurement approach significantly reducing the size, weight, and cost of the alignment system.

  • Patent number: 10466036
    Abstract: An imager utilizes a division of focal plane polarization and color camera to measure motion, depth and orientation of objects in a scene in real-time. In various examples, structured light, polarization-controlled discrete reflectors, and/or spatially varying discrete light sources are used to provide light of controlled polarization and color from an object in a scene to a camera. The camera utilizes a pixelated optical filter with a pattern of varying polarization filters across the pixel array, and optionally an integrated color filter pattern. Light measurements are processed to determine polarization state of light received from the object, whence orientation, position, and/or other properties of the object are determined. Systems are operable with a single camera. Applications include virtual reality, gaming, robotics, autonomous vehicles, tele-surgery, industrial automation, 3-D scanning, surveillance, and remote interaction.

  • Patent number: 10444145
    Abstract: A mid-wave infrared system provides high spatial and temporal resolution measurements of atmospheric temperatures and moisture fields using a constellation of low earth orbit satellites. The disclosed system is smaller, lighter, less complex, and requires less energy than existing systems, due to implementation of an infrared avalanche photodiode array detector that provides enhanced sensitivity with reduced cooling requirements, and an Offner spectrometer having a novel a refractive element inserted near the grating that reduces the size and power requirements of the spectrometer. Embodiments of the disclosed method include deploying a constellation of devices for cooperative infrared sensing of atmospheric phenomena at similar rates, lower cost, and much higher resolution compared to geosynchronous approaches.
