相显微镜的高动态范围定量相衬成像的透明相对象进行了演示。利用共程傅里叶域光学相干层析成像系统，该技术能够以34 pm的灵敏度进行位移测量。利用谱域的相位检索方法克服了2 π模糊限制的局限性。二维定量相成像的人新生儿真皮角质形成细胞被证明，以评估系统的性能为细胞成像。
Phase microscopy for high-dynamic-range quantitative phase-contrast imaging of a transparent phase object was demonstrated. Using a common path Fourier domain optical coherence tomography system, this technique is capable of displacement measurement with a sensitivity of 34 pm. The limitation of 2 π ambiguity restriction was overcome by the use of a phase retrieval approach performed in spectral domain. Two-dimensional quantitative phase imaging of human neonatal dermal keratinocyte cells was demonstrated to evaluate the performance of the system for cell imaging.
