WebWe demonstrate spectroscopic photonic force optical coherence elastography (PF-OCE). Oscillations of microparticles embedded in viscoelastic hydrogels were induced by harmonically modulated optical radiation pressure and measured by phase-sensitive spectral-domain optical coherence tomography. PF-OCE can detect microparticle … WebPrinciple of photonic force OCE Inspired by the pioneering work of Nobel laureate Arthur Ashkin35, we exploited a less conventional mode of optical manipulation, based on radiation pressure from a low-NA beam, to develop photonic force (PF)-OCE for 3D mechanical microscopy36. PF-OCE utilizes radiation pressure from a low-NA beam (NA ≤ 0.4 ...
