Abstract:
1. A method for imaging a scene, comprising: recording a first image of the scene, comprising: moving the first optical element in the reference frame of the imager after recording the first image, such that after moving the first optical element, radiation ray bundles having the first chief ray that are received after moving the first optical element are received by, and optically processed by, at least one of the second portion of the first optical element and a third portion of the first optical element, the third portion of the first optical element having a third optical characteristic with respect to radiation ray bundles having the first chief ray that are received after moving the first optical element optically processed by the third portion of the first optical element, the third optical characteristic being different from the first optical characteristic; recording a second image after moving the first optical element, comprising: processing the first and third intensity values to derive at least one value representing at least one of an intensity of radiation emanating from the first portion of the scene, a spectral distribution of radiation emanating from the first portion of the scene, a polarization parameter of radiation emanating from the first portion of the scene, and a distance between the imager and the first portion of the scene.
