A new aerosol and cloud polarimetry sensing (ACPS) has been presented to measure four polarization components of eight specific wavelengths selected from 400∼ 2400 nm simultaneously. The ACPS system can provide high accurate polarized intensity components of atmospheric radiance with a simple and compact structure. The ACPS structure can be regarded as a 4-f Fourier optics system. It takes Wollaston prisms as polarimeters, uses filters and slits to select the appropriate wavelength, and locates the monochromatic polarized light images on different places of focal plane. In our approach, the visible Part 1 is designed as an example and all fields MTFs of Part 1 are larger than 0.5 at detectors’ Nyquist frequency 20 lp/mm.
