Lens array Stokes imaging polarimeter

We have successfully constructed and tested two portable multi-lens polarization cameras whose designs differ in the ability to measure circularly polarized light. The cameras operate by acquiring multiple images of a scene at different polarizations using multiple lenses. An algorithm is used to align and combine the images, correcting for exposure and lens variation, to generate accurate Stokes images. Comparisons are made between four- and eight-lens Stokes imaging cameras. The multi-lens camera and software error corrections can be implemented at a relatively low cost.
