Refractive Pyramide
Apr. 10, 2012
Classical phase contrast microscopy techniques allow only non-quantitative partial visualization of transparent samples. In recent years, a variety of techniques have appeared for complete phase determination with different levels of complexity. A new simple non-interferometric method able to provide real time quantitative optical path difference information is presented. It is based on the use of a refractive pyramid to measure the transillumination wavefront gradient using incoherent light.
