Laser interference microscopy (LIM) is a modern and unique cell imaging technique which allows to see real-time changes in the local IOP of a cell. Here we present the results of the LIM application with consequent wavelet analysis for cell visualization and cellular dynamics study. ... Temporal variations of the local RI were also studied. ... 2007 Biophysics dep., ...
