摘要:
The invention pertains to an aerosol detector system for spatially resolved detection of an aerosol distribution in an area, comprising: a wide field polarization preserving telescope having telecentric imaging optics for imaging the earth surface onto a detector; said detector receiving phase stepped images imaged by said telescope; and a controller coupled to the detector, arranged to provide a resulting image as a function of corresponding pixel values of the multiple images to produce an image at a spatially resolved polarization state corresponding to said aerosol substance; wherein the telescope comprises a first telecentric imaging lens group and a wavelength filter positioned in a field image of the first telescope telecentric beam to define a spectral range of interest; the telescope further comprising: a converging lens group converging the beam to a pupil stop; relay optics including a second telecentric imaging lens group arranged to generate a telecentric beam; and splitter optics, comprising a p
