DH obtains both amplitude and phase distributions of an object wave simultaneously and quantitatively. The application of DH to microscopy is called digital holographic microscopy (DHM). DHM is also called 3D microscopy [14, 18] and quantitative phase microscopy [14, 17, 19]. The amount of phase shift is determined by the optical thickness, which depends on both the index of refraction inside the object and the object thickness. The phase shift can be measured with a resolution down to nanometers [5].

Phase holographic microscopy

The phase shift image is unique for digital holographic microscopy and gives quantifiable information about optical distance. In reflection DHM, the phase shift image forms a topography image of the object. Quantitative phase-digital holographic microscopy (QP-DHM) represents an important and efficient quantitative phase method to explore cell structure and dynamics. In a second part, the most relevant QPM applications in the field of cell biology are summarized. Holographic microscopy We use a fast imaging method called holographic microscopy to watch self-assembling systems. In a holographic microscope, the sample is illuminated by laser light, and the resulting image (or hologram) can be used to determine the 3D structure, position, and orientation of a microscopic sample.

However, these imaging techniques currently lack molecular contrast agents analogous to the fluorescent dyes and proteins that have revolutionized fluorescence microscopy. Here we introduce … The proposed method decomposes the phase map into a set of values of uncorrelated variables called principal components, and then extracts the aberration terms from the first principal component obtained.
