Abstract :
A high-dynamic-range two-dimensional phase measurement system that does not need phase unwrapping processing was developed. The optical path difference distribution about three wavelengths could be measured, demonstrating the high dynamic-range of this system. We also experimentally investigate the potential of this approach for biological applications that are cancer identification and assessing the limitations of the passage culture of biological cells.
