Scan-less Hyperspectral Polarimetric Imaging Using Dual-Comb Single-Pixel Imaging

Abstract

Spectroscopic polarimetry enables detailed characterization of light-matter interactions by combining spectral and polarization information, yet conventional implementations rely on mechanical polarization modulation and are difficult to extend to fast, broadband imaging. Dual-comb spectroscopic polarimetry (DCSP) addresses these limitations by providing rapid, modulation-free access to polarization-resolved amplitude and phase spectra, but has so far been limited to point-based measurements. In this work, we introduce dual-comb spectro-polarimetric single-pixel imaging (DCSP-SPI), a new framework that combines DCSP with structured illumination and single-pixel detection to achieve scan-less hyperspectral polarimetric imaging without a camera. By exploiting the intrinsic amplitude and phase sensitivity of dual-comb interferometry, spectrally resolved images of the amplitude ratio psi and phase difference delta are reconstructed across a broad optical spectrum. The performance of DCSP-SPI is demonstrated through imaging experiments using a birefringent resolution target and a Fabry-Perot etalon, where frequency-dependent psi and delta images are obtained and shown to follow the expected spectral and polarization characteristics. Furthermore, the approach is extended to hyperspectral reconstruction of full Jones matrix elements by using multiple incident polarization states. The proposed DCSP-SPI framework provides a new pathway toward scan-less, hyperspectral polarization imaging, offering a flexible platform for applications requiring quantitative spatial, spectral, and polarization analysis.
