Refractive index
The refractive index of a tissue is a measure of light speed reduction in a given tissue. In other words, the higher the refractive index the slower the light travels.
Cell refractive index is a key biophysical parameter that represents the intracellular mass concentrate and provides important insight for various biological models including cell biology, hematology, and pathology.
Q-Phase measures the light phase shift across the sample determined by two parameters: the refractive index of the sample and its thickness.
The refractive index distribution of a sample can be calculated using Q-Phase by measuring the phase shift across the sample on two occasions where the sample is being impeded in two well-known RI media.
