abstract = "A dual-wavelength common-path digital holographic microscopy is presented to simultaneously improve the phase measurement accuracy and stability. Two laser beams with different wavelength are reflected by the front and back surface of a parallel glass plate to form the composite hologram in the lateral shearing region, and a shorter synthetic wavelength Λ289nm is obtained by calculating the arctangent and product of the two reconstructed complex amplitudes. Thus, phase speckle noise can be reduced in the dual-wavelength numerical reconstruction process, and the phase measurement accuracy and stability can be improved. The experiment results of the peony pollens specimen show the feasibility of the proposed configuration.",
