Abstract: An axicon scatter filter assembly operates on light that is approximately temporally and spatially coherent (requiring either active illumination or a very narrow field of view). The filter exploits the difference in behavior between spatially coherent and spatially incoherent light. Spatially coherent light is shaped and moved by the axicons. This allows the spatially coherent light to diverge and then be reconstructed into a rectified image. The spatially incoherent light is neither shaped nor moved by the axicons. Where the coherent light diverges, the incoherent (scattered) light does not. Thus, masks can be used to block a portion of the incoherent light while passing all of the incoherent light. The filter assembly thus removes undesired scattered light that degrades image quality. The axicons then reconstruct the original image with less scattering, which can be imaged by a lens and camera.
