Hybrid single-pixel camera switching mode for spatial and spot/area measurements

摘要

Disclosed herein is a single-pixel camera system and method for performing spot/area measurement of a localized area of interest identified in a scene and for performing spatial scene reconstruction. A switching module enables a single-pixel camera to alternate between a spot/area measurement mode and a spatial scene reconstruction mode. In the case where the operative mode is switched to spot measurement, a light modulation device is configured to modulate incoming light according to a clustered pattern that is specific to a localized area of interest intended to be measured by integrating across the pixels to generate an integral value. In the case where the operative mode is switched to spatial scene reconstruction, the light modulation device can be configured to modulate incoming light to display a spatial pattern corresponding to a set of predetermined basis functions.

1. A method for using a single-pixel camera system for spot measurement, the method comprising:
configuring a light modulation device comprising an array of imaging elements to spatially modulate incoming light according to a clustered pattern that enables spot measurement of a localized area of interest, said clustered pattern being specific to said localized area; measuring, using a photodetector of a single-pixel camera, a magnitude of an intensity of said modulated light across pixel locations in said clustered pattern; wherein said magnitude of an intensity is equivalent to an integral value of the scene across said pixel locations; and, wherein said integral value comprises a spot measurement.
