Patent attributes
A combined multi-spectral and polarization (CMSP) sensor is disclosed that enhances contrast-to-noise ratio (CNR). The CMSP sensor comprises a multi-spectral and polarization (MSP) filter, a single focal plane array (FPA), and a controller. The FPA comprises a plurality of detectors and the MSP filter comprises at least a first bandpass filter having a first frequency range and a second bandpass filter having a second frequency range that is distinct from the first frequency range and a first polarization filter having a first polarization value and a second polarization filter having a second polarization value that is distinct from the first polarization value.
