The invention discloses a micro-polarization array design model and an array arrangement mode acquisition method based on the micro-polarization array design model, belongs to the field of polarization optical devices, and mainly relates to a polarization optical technology, a focal plane type
polarization imaging detection technology, a Fourier
frequency domain optical analysis technology and thelike. According to the model, structural design can be carried out on 2*N series and N*N series micro-polarization arrays, the distances and positions among all components in a two-dimensional
frequency domain are optimized by changing parameters a, b and c of the design model, and the bandwidth range among the components which is not influenced by
crosstalk is increased, so that the reconstruction quality of Stokes parameter images and DoLP images is improved. According to the design model, from the perspective of two-dimensional
frequency domain analysis, the design and acquisition steps ofthe micro-polarization array arrangement mode are simplified, the design range of the array arrangement mode is expanded, a theoretical basis is provided for development of a high-performance micro-polarization array, and high-quality Stokes parameter image reconstruction is realized. And the practical application of the focal plane type
polarization imaging system is promoted.
