Figure 5From: Measurement of intrinsic optical backscattering characteristics of cells using fiber-guided near infrared light The changes of scattering light in response to a 7-min exposure to ± 20, ± 40 and ± 60 mOsm of osmotic challenges. The time-course plots of (a) the relative amplitude (ΔRa) and (b) relative phase shift (ΔRp) under different osmotic conditions. The negative ΔRp indicates the leading in phase compared to that of cells before osmotic challenge.Back to article page
