| titleOfInvention | Hybrid spectral imaging devices, systems and methods |
| abstract | A hybrid spectral imager apparatus has an imaging head arrangement (IHA), a control and processing unit (CPU), and a display. The IHA includes an optical imager, multiband filtering optics (MBFO), and a sensor arrangement. The optical imager collects and focuses an image of a target scene or object along an imaging path. The multiband optics includes a beam divider for generating at least two replica images of the target image, and a multiband filter (MF) interposed into the imaging path and effecting multi-bandpass filtering in the image replicas. The sensor arrangement has at least one Mosaic filter array (MFA) focal plane array (FPA) sensor onto which the multiband filtered image replicas are focused, and a focal plane array masked, in a pixelized manner, with at least three wide-band primary color-type filters, with each primary color-type response separating and capturing one single-band. The CPU is coupled to the IHA and is configured to execute program instructions for calibrating image acquisition processes, controlling and synchronizing the acquisition/capturing of the image replicas by the MFA sensor arrangement, and spectrally purifying the MFA sensor arrangement responses to compensate band cross-talking between the MFA and the MF. The display is configured to display on a user interface at least the acquired single-band images. The CPU is further configured to reconstruct and display, on the display, a set of at least three different single-band images per MFA-FPA sensor employed. The IHA is configured to capture sets of different single-band images for video snapshot spectral imaging at desired spectral bands within the FPA sensor arrangement spectral sensitivity range. |
