Abstract: • A snapshot miniature spectropolarimetric imaging system based on the modulation of a single multi-order retarder, MINI-ORRISp, is achieved for real-time acquisition of multi-dimensional optical information over dynamic scenes. • The spatial, spectral, radiometric, and polarimetric calibration processes for MINI-ORRISp are presented in detail, especially an advanced registration method based on the adaptive parallax estimation and matching method is proposed. • The portable high-performance MINI-ORRISp has potential applications in field of in fields of UAV and UGA remote sensing, auto autopilot assistance, mineral mining, man-portable reconnaissance operations, and biomedical diagnosis, etc. A high-performance snapshot Miniature Optically Replicating and Remapping Imaging Spectropolarimeter (MINI-ORRISp) for the acquisition of 3D data cubes (x, y, λ) for each of four Stokes parameters (S 0 , S 1 , S 2 , S 3) is developed. It uses the simplest passive polarization modulator (PM) consisting of only a single multi-order retarder followed by a linear polarizer to encode the 3D data cubes into our single-2D-detector-based snapshot imaging spectrometer, and employs an untrained-network-based self-calibrating reconstruction algorithm to decode the data cubes. The developed MINI-ORRISp prototype provides video-rate acquisition of 3D data cubes (400 × 400 × 72) for each Stokes parameter over a wide spectral range of 400–850 nm. The portable prototype has a miniature size of 60 × 66 × 53 mm3 and a light weight of 410 g. Essential details of the opto-mechanical design as well as the calibration and performance characterization are presented. Extensive experimental results are provided to demonstrate the ability of the MINI-ORRISp to obtain high-quality spectropolarimetric images from both static and dynamic scenes. [ABSTRACT FROM AUTHOR]
