Abstract
Infrared polarimetry is a powerful label-free diagnostic tool to study the molecular alignment and organization in biological tissues and cells. Similar to absorbance images which capture intensity information, polarimetric imaging is essential for capturing the polarization states of the light intensity. Recent advancements in the development of Quantum Cascade Lasers (QCL) sources have opened new avenues in IR imaging with high spatial and spectral resolution while enabling drastic increases in imaging speeds than a corresponding FT-IR approach. We demonstrate improved performance in terms of fast and comprehensive polarimetric image acquisition using a custom-built QCL microscope with point mapping design.
