Abstract

Several aspects of the invention respectively record one or more multispectral (MS) images using at least one sensor array, each array getting one respective image and simultaneously polarization state at the array points; and get and displays a MS, multipolarization (MP) movie, at MS/MP frame rates that suit a scene or the acquisition; and get an MS image, and a polarization-state image, so that the two are inherently in register; and provide a digital camera for plural-waveband imaging, including polarization data, using a chip with an optically sensitive layer continuously spanning a field of view—for each of at least two substantially distinct bands, and with stacked layers, some radiation penetrating plural layers to a corresponding sensitive layer, and with a polarization mosaic over the stack to define a superpixel array that differentiates polarization states, and with an electronic shutter actuating the layers. Another aspect makes a time sequence of registered MS/MP images; and yet another gets data for one or more MS images, including polarization state at most image points, via a single, common aperture.
