Abstract

A method is provided for constructing a three-dimensional hyperspectral image using compressive sensing. The method includes: configuring on/off state of each mirror in an array of micromirrors in accordance with a pattern; capturing image data of a scene from a first point of view using a first photodetector; and capturing image data of the scene from second point of view using a second photodetector, where second point of view differs from the first point of view. The steps are repeated to obtain a series of measurement samples, where the array of micromirrors is configured in accordance with a pattern that differs amongst each measurement samples. By choosing different photodetectors with different band gap nanomaterials, the first and second photodetectors detects photons in the electromagnetic spectrum. As a result, the three-dimensional image also carry the spectrum information of the scene.
