Figure 6From: Measurement of intrinsic optical backscattering characteristics of cells using fiber-guided near infrared light The largest change in light intensity and phase shift to the different levels of osmotic change. (a) shows an inverse relationship between osmolality and relative intensity (ΔRa) (b) The relative phase shift (ΔRp) decreases with the decrease of osmotic pressure but reaches a plateau at high osmotic pressure.Back to article page
