  • Patent number: 11070747
    Abstract: Various techniques are provided for implementing a segmented focal plane array (FPA) of infrared sensors. In one example, a system includes a segmented FPA. The segmented FPA includes a top die having an array of infrared sensors (e.g., bolometers). The top die may also include a portion of a read-out integrated circuit (ROIC). The segmented FPA also includes a bottom die having at least a portion of the ROIC. The top and the bottom dies are electrically coupled via inter-die connections. Advantageously, the segmented FPA may be fabricated with a higher yield and a smaller footprint compared with conventional FPA architectures. Moreover, the segmented FPA may be fabricated using different semiconductor processes for each die.

  • Patent number: 11029211
    Abstract: Flight based infrared imaging systems and related techniques, and in particular UAS based thermal imaging systems, are provided to improve the monitoring capabilities of such systems over conventional infrared monitoring systems. An infrared imaging system is configured to compensate for various environmental effects (e.g., position and/or strength of the sun, atmospheric effects) to provide high resolution and accuracy radiometric measurements of targets imaged by the infrared imaging system. An infrared imaging system is alternatively configured to monitor and determine environmental conditions, modify data received from infrared imaging systems and other systems, modify flight paths and other commands, and/or create a representation of the environment.

  • Publication number: 20210133510
    Abstract: Various techniques are provided for training a neural network to classify images. A convolutional neural network (CNN) is trained using training dataset comprising a plurality of synthetic images. The CNN training process tracks image-related metrics and other informative metrics as the training dataset is processed. The trained inference CNN may then be tested using a validation dataset of real images to generate performance results (e.g., whether a training image was properly or improperly labeled by the trained inference CNN). In one or more embodiments, a training dataset and analysis engine extracts and analyzes the informative metrics and performance results, generates parameters for a modified training dataset to improve CNN performance, and generates corresponding instructions to a synthetic image generator to generate a new training dataset. The process repeats in an iterative fashion to build a final training dataset for use in training an inference CNN.

  • Publication number: 20210091270
    Abstract: A light-emitting device includes a substrate that is at least partially transparent to optical radiation and has a first index of refraction. A diode region is disposed on a first surface of the substrate and is configured to emit light responsive to a voltage applied thereto. An encapsulation layer may be disposed on a second surface of the substrate and has a second index of refraction. An antireflective layer stack is formed within the substrate directly below the second surface of the substrate. The antireflective layer has an amorphous non-porous first layer, a porous second layer, an optional amorphous non porous third layer, and a fourth layer with modified crystallinity. The encapsulation layer may also be omitted and the substrate's second surface may separate the substrate, which has an antireflective layer stack within the substrate, directly below the second substrate surface, from air.

    Abstract: An anatomical structure is segmented from images generated in an anatomical scan. A user input device is configured for manually identifying two or more seed points on a plurality of the images. An image processor is configured to identify an optimal path through seed points on the plurality of images with a graph search.

  • Patent number: 10393575
    Abstract: Techniques are provided to perform flat field correction for infrared cameras using a liquid shutter. Devices and methods provide a focal plane array (FPA) that receives infrared radiation (e.g., thermal infrared radiation) from a scene, and infrared-opaque liquid disposed in a cavity of a liquid shutter housing, and a fluid controller that directs the liquid from a reservoir area of the cavity to a field of view area of the cavity to block the FPA from the infrared radiation. Flat field correction terms may be determined and radiometric calibration may be performed. In one example, a liquid shutter uses voltages to direct liquid. In another example, a liquid shutter uses magnetic fields from electromagnets to direct liquid such as ferrofluid. In another example, a liquid shutter uses electrowetting techniques to direct liquid such as water. In a further example, a liquid shutter uses a pump.

  • Patent number: 10389953
    Abstract: A shutter assembly may be provided for an infrared imaging module to selectively block external infrared radiation from reaching infrared sensors of the infrared imaging module. For example, the shutter assembly may comprise a paddle situated external to an optical element (e.g., lens) and adapted to be selectively moved by an actuator to substantially block external infrared radiation from entering the optical element. The shutter assembly may be stacked relative to a housing of the infrared imaging module without excessively increasing the overall profile of the infrared imaging module. A substantially reflective low emissivity interior surface may be provided on the paddle to reflect infrared radiation originating from an infrared sensor assembly of the infrared imaging module back to the infrared sensor assembly.

  • Patent number: 10321076
    Abstract: A partially attenuating shutter may be used to identify and reduce fixed pattern noise (FPN) associated with imaging devices. In one example, a system includes an image capture component configured to capture images in response to incident radiation from a scene along an optical path. The system includes a shutter configured to attenuate a first portion of the incident radiation and permit a second portion of the incident radiation to pass. The system also includes an actuator configured to translate the shutter between an open position out of the optical path, and a closed position in the optical path between the scene and the image capture component. The system also includes a processor configured to determine a plurality of FPN correction terms using images captured by the image capture component while the shutter is in the open and closed positions. Related systems and methods are also provided.
