Multiplex optical systems are designed to mix information channels on sensors. This paper considers the use of multiplex sensors to embed scene analysis in the optical layer of imaging systems. The goals of embedded analysis are to reduce the system data and processing load and to improve analytic accuracy by low-level filtering. We show specifically that filtering on the cross spectral density during detection allows the construction of sensors that integrate spatio-spectral patterns from specific volumes and that coded illumination patterns can structure the radiated cross spectrum to enable digital focusing on particular source characteristics.
