Figure 3From: Measurement of intrinsic optical backscattering characteristics of cells using fiber-guided near infrared light The relationship between the averaged intensity and phase data measured at various distances from the tip of fiber-optical probe to the surface of culture dish. The sigmoid-like trend in the intensity (-o-) of optical output is found with the increase of measuring distance, which peaks around 1250 μm. Opposite trend can be observed in the phase information, with a minimum around 1250 μm.Back to article page
