Abstract: Event vision sensors with event data compression (and associated systems, devices, and methods) are disclosed herein. In one embodiment, an event vision sensor includes a plurality of event vision pixels. Each event vision pixel of the plurality is configured to generate event data based on events indicated in incident light received from an external scene, and includes a compression circuit configured to compress the event data prior to readout of the event data from the event vision pixel. Each compression circuit can include a time aggregation circuit that is configured to track a number of the events detected by the corresponding event vision pixel over a specified timing window. The compressed event data can be read out from the event vision sensors and used to generate a pseudo-frame. The event vision sensor can optionally perform frame-level compression on the pseudo-frame.

Abstract: A method of imaging surface features with a large (non-microscopic) field-of-view includes projecting a structured illumination pattern onto the transparent target. The surface features modify the structured illumination pattern, and an image of the modified structured illumination pattern is imaged at each of multiple different introduced phase shifts via an imaging device. The method further provides for extracting, from each of the captured phase-shifted images, image components that correspond to frequencies exceeding a cutoff frequency of the imaging device; and using the extracted image components to construct a corrected image of the surface features of the transparent target. The corrected image has a resolution that is greater than a spatially incoherent point-to-point optical resolution of the imaging device.
