Abstract
We demonstrate polarimetric coherent anti-Stokes Raman scattering (PCARS) microscopy for quantitative analysis of collagen orientation. Using polarization-modulated excitation and cross-polarized detection, we extract both chemical and orientational information from intact tissues. We introduce two complementary analyses: the CARS peak polarization ratio (PPR) and Fourier domain polarimetric analysis, providing a robust characterization of collagen organization. This method enables rapid, label-free imaging of a collagen structure with molecular specificity, offering what we believe to be new capabilities for studying collagen remodeling in biological processes.
期刊介绍:
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
