Abstract:
A multispectral staring array (10) comprises, amongst other things, at least two sensors (28, 30) where each sensor is adapted to detect an image in a different predetermined spectral sensitivity; a first lens (14) to focus capture spectral bands; a spectral filter (20, 22) between the lens (14) and the sensors (28, 30) to subdivide the incident spectral bands; and a second lens (24, 26) to direct and focus the subdivided incident spectral bands on each of the sensors (28, 30).

Exemplary systems and methods for filtering an electromagnetic radiation can be provided. For example, at least one first arrangement (4) can be provided which is capable of receiving at least one first electro-magnetic radiation and forwarding at least one second electro-magnetic radiation at different angles with respect to a direction of incidence of the first electro-magnetic radiation. At least one second wavelength dispersion arrangement (5) can be provided which is configured to receive the second electro-magnetic radiation, forward at least one third electro-magnetic radiation to the first arrangement (4) and further receive at least one fourth electro-magnetic radiation. The third electro-magnetic radiation can be based on the second electro-magnetic radiation, and the fourth electro-magnetic radiation can be based on the third electro-magnetic radiation. For example, the second arrangement can be configured to forward the second electro-magnetic radiation at different angles with respect to a direction of incidence of the at least one particular electro-magnetic radiation.
