Abstract

We demonstrate a new portable multi-wavelength fiber-based quantitative phase microscope (FQPM). In FQPM, the reference beam is made to propagate in a single-mode optical fiber whose length is tuned to ensure the best interference contrast with the sample beam. For further compactness, different illumination wavelengths are multiplexing through fiber combiners and couplers. FQPM simultaneously acquires the sample interferograms coming from two illumination wavelengths in a single shot, and their corresponding phase maps can be obtained separately. We have used FQPM for imaging dispersive samples, such as fluorescence particles and red blood cells and further analyze the refractive index and intracellular hemoglobin concentration.
