摘要： Techniques are disclosed for analog-to-digital conversion systems and methods with pulse generators. In one example, an imaging system includes an analog-to-digital converter (ADC). The ADC includes a comparator configured to generate a comparator output signal based on a first signal and a second signal. The comparator output signal is associated with a first state or a second state. The ADC further includes a pulse generator coupled to the comparator. The pulse generator is configured to generate a pulse signal in response to a transition of the comparator output signal from the first state to the second state. The ADC further includes a memory device coupled to the pulse generator. The memory device is configured to capture a counter value from a counter circuit in response to the pulse signal. The counter value is associated with the detector signal. Related methods are also provided.

摘要： Techniques are disclosed for facilitating detection of electromagnetic radiation using superlattice-based detector systems and methods. In one example, an infrared detector includes a first superlattice structure including first periods. Each of the first periods includes a first sub-layer and a second sub-layer adjacent to the first sub-layer. The first and second sub-layers include first and second semiconductor materials. The infrared detector further includes a second superlattice structure disposed on the first superlattice structure. The second superlattice structure includes second periods. Each of the second periods includes a third sub-layer and a fourth sub-layer adjacent to the third sub-layer. The third-sub-layer includes a third semiconductor material. The fourth sub-layer includes a fourth semiconductor material. A p-n junction is formed at an interface within the second superlattice structure or at an interface between the first and second superlattice structures.

摘要： Techniques are disclosed for facilitating dual color detection. In one example, an imaging device includes a first pixel configured to detect first image data associated with a first waveband of electromagnetic radiation. The imaging device further includes a second pixel configured to detect second image data associated with a second waveband of the electromagnetic radiation, where at least a portion of the second waveband does not overlap the first waveband. The imaging device further includes a bias circuit configured to apply a first voltage between the first pixel and a first ground contact, and apply a second voltage between the second pixel and a second ground contact.

摘要： An image classification system comprises a neural network trained on a synthetic infrared training dataset, including synthetic infrared images of objects rendered from a virtually represented infrared sensor in a virtual three-dimensional scene, the synthetic infrared images being generated using infrared radiation signatures of virtual objects in the virtual three-dimensional scene and an infrared response model of the virtually represented infrared sensor. A system for generating synthetic infrared training data comprises a three-dimensional scene modeling system operable to generate three-dimensional scenes comprising a plurality of objects, each object having an infrared radiation model, and an infrared sensor modeling system operable to model an imaging response for an infrared sensor virtually represented in the three-dimensional scene.
