Point-Scanning QPI Methods
1010103Point-Scanning QPI MethodsIn this chapter, we review the principle of quantitative phase methods based on point measurements, in which the image is reconstructed via scanning. These types of measurements can be regarded as an extension to optical coherence tomography (OCT), which is an intensity-based interferometric technique. OCT is a label-free (i.e., intrinsic contrast) method that enables 3D imaging of tissues. Developed in the Fujimoto Laboratory at Massachusetts Institute of Technology,1 the principle of OCT relies on low-coherence interferometry (LCI), i.e., interferometry with broa…
