WebOptical Interferometry for Biology and Medicine is divided into four sections. The first covers fundamental principles, and the next three move up successive scales, beginning with molecular interferometry (biosensors), moving to cellular interferometry (microscopy), and ending with tissue interferometry (biomedical). ... WebInterferometry. To understand interferometry, you need to understand interference, phase, and waves. The basic idea is to take a beam of light, split it into two equal halves, send one down a reference path, the other down a test path, and collect the reflected light at a detector. In our static example to the left: the beam leaves the light ...
