“…In general, it is required to combine the phase-shifting technique to retrieval phase .In 1997, the group of Yamaguchi [11] first introduced the phase-shift method to the on-axis digital holography and got an experimental verification. Then, many other phase-shift digital holographic phase microscopy techniques have been successively reported [12][13][14][15], such as Awatsuji and etc from 2004 to 2006, respectively, put forward parallel quasi four steps [12] and three phase shift holographic technology [13] to realized 3D images of a object. In 2012, Samsheerali [15] reported a coaxial phase-shift digital holographic technology with the help of a diffraction grating phase, which realized the high stability of the quantitative phase imaging.…”

Abstract. Optical interference is an important technique in precision measurement and microscopy imaging. Especially, phase imaging technology of the biological cell has attracted increasing attention. In this paper, considering the high stability characteristics of the coaxial interference technique, one interference imaging system that can do both coaxial and off-axis phase imaging is constructed by using a couple of Dove prisms and a beam splitter without other lens, all the system structure based on a con beam that is simple and can image the phase of a cell after placing a post amplification. It can be obtained by some phase recovery methods for the thickness distribution of a cell, so that, the shape of a homogeneous cell can be shown. Simulation and experimental results have verified the feasibility and correctness of the system. It is one kind of cell morphology analysis technology with simple and practical.

“…Traditional interferometers [5][6][7][8], such as the Mach-Zehnder or Michelson interferometers, are subject to error because of environmental effects such as vibrations, air turbulence, and temperature on the wide separated paths of the object and reference beam. Thus, common-path interferometers [9][10][11][12][13][14][15][16][17] are of growing interests due to the inherent robustness in the setup, where the object and reference beam travel almost in the same path. For example, Shaked [13] proposed an off-axis common-path interferometer using a modified Michelson architecture.…”

“…A two-window common-path interferometer with simultaneous phase shifting [19][20][21][22] has been proposed recently; it includes two windows in the object plane and a grating in the Fourier plane of a 4f system, respectively, and uses polarization elements to achieve phase shifting. These methods can realize high-stability and low-noise real-time measurement, but the utilization of FOV is decreased.…”

A new method is presented using a tri-window common-path interferometer (TriWCPI) for quantitative phase measurement. The prior method obtains the phase shift introduced by the Ronchi grating and the intensity value of the incident light with interferograms acquired offline without any objects. As a consequence, an improved recovery algorithm is established using the phase shift, the intensity value of the incident light, and the interferograms for a phase object acquired by camera in a single shot. The phase of an object then can be reconstructed from the improved algorithm. Because the calculation of phase shift and intensity value can be performed offline only once after the TriWCPI is built, the real-time ability and stability of the TriWCPI remains in this method. But the method avoids the normalization process and thus improves phase-retrieval precision. Experiments are demonstrated to prove the precision, real-time ability, and stability of the proposed method.
