Computational coherent superposition self-reference digital holographic microscopy for multiwavelength 3D information acquisition
Abstrak
I propose a digital holographic microscopy technique in which complex amplitude distributions at multiple wavelengths are simultaneously obtained with a common-path self-reference interferometer and a monochrome image sensor. The computational coherent superposition scheme is applied to reconstruct a multiwavelength holographic image from a small number of wavelength-multiplexed phase-shifted holograms. Optical systems adopting a commercially available optical microscope with a light-emitting diode and a halogen lamp are constructed and their applicabilities to multiwavelength three-dimensional microscopy and quantitative phase microscopy are experimentally demonstrated. The possibility of single-shot measurement with a monochrome image sensor is discussed.
