Abstract: A method for regulating a position of an object includes detecting a plurality of first alignment structures of the object under rotation of the object, wherein a plurality of second alignment structures of the object sequentially face a photosensitive element during the rotation of the object, and when the plurality of first alignment structures have reached a first predetermined state, stopping the rotation of the object and performing an image capturing procedure of the object. The image capturing procedure includes: capturing a test image of the object, wherein the test image includes an image block presenting the second alignment structure currently facing the photosensitive element; detecting the position of the image block in the test image; when the image block is located in the middle of the test image, capturing a detection image of the object.

Abstract: A technology is described for hyperspectral imaging. An example of the technology can include receiving an event stream of events from an event camera coupled to an interferometer. The event camera can receive light output from the interferometer and generate the event stream, comprising event data that corresponds to the light output. The events in the event stream can indicate a pixel that detected an event, a time of the event, and a polarity of change in brightness detected by the pixel. Spectral data can be generated for the events in the event stream using a demodulation and frequency transform to convert temporospatial aggregates of events in the event stream to frequency domain data that corresponds to an optical spectrum. A hyperspectral image of an input scene in a spectral range can be generated using the spectral data.
