Coherent Anti-Stokes Raman Scattering (CARS) Microscopy for Bioimaging

The book explores the advancements in coherent anti-Stokes Raman scattering (CARS) microscopy, particularly its application in biological imaging. It addresses the challenges of nonresonant background noise and diffraction-limited resolution. Through systematic research on nanoparticle effects, a radially polarized near-field tip-enhanced CARS system is developed, along with an innovative annular-aperture detection scheme to enhance image quality. This novel technique promises significant insights into tissue and cellular changes without the need for labeling, advancing understanding in biomedical research.
