Optical interferometry
WebIn optical interferometry, light waves are recombined after propagating along separate paths. Depending on the difference in the waves' phase accumulated along the two paths, the light may interfere constructively and appear … WebOptical biometry explained. Optical biometry is the current standard for intraocular lens (IOL) power calculations in clinical practice. Optical biometry is a highly accurate non-invasive automated method for measuring the anatomical characteristics of the eye. Accurate measurements are critical for determining the correct power of an IOL ...
