Multi-wavelength imaging diffraction system is a promising phase imaging technology with advantages of no mechanical movement and low complexity. Spectral bandwidth and dispersion correction are critical for high resolution reconstruction in this system. Using three beams with different wavelengths and robust refocusing technique for chromatic correction, high-resolution images can be retrieved through a phase retrieval algorithm, demonstrating the potential as an alternative technology for quantitative biological imaging.
Multi-wavelength imaging diffraction system is a promising phase imaging technology due to its advantages of no mechanical movement and low complexity. In a multi-wavelength focused system, spectral bandwidth and dispersion correction are critical for high resolution reconstruction. Here, an optical setup for the multi-wavelength lensless diffraction imaging system with adaptive dispersion correction is proposed. Three beams with different wavelengths are adopted to illuminate the test object, and then the diffraction patterns are recorded by a image sensor. The chromatic correction is successfully realized by a robust refocusing technique. Highresolution images can be finally retrieved through phase retrieval algorithm. The effectiveness and reliability of our method is demonstrated in numerical simulation and experiments. The proposed method has the potential to be an alternative technology for quantitative biological imaging.
