Description

Holographic microscopic imaging device
Technical Field
The invention relates to the technical field of microscopic imaging technology, interference imaging and phase imaging, in particular to a holographic microscopic imaging device.
Background
The optical field interacts with the non-homogeneous medium by modulating the wavefront and amplitude of the light, a process known as scattering of the light. Generally only elastic scattering is considered, i.e. the wavelength of the light after scattering is unchanged. Because the amplitude and phase of the scattered light carry the internal structure information of the scattering object, the structure of the object can be recovered by measuring the scattered field, and the process is called as the solution of the backscattering problem. This is the basis for tomographic imaging of transparent biological tissues or cells. The long-felt need for tomographic imaging of unlabeled three-dimensional living specimens has led to new phase imaging techniques, since intracellular tissue has many highly dynamic structures that are difficult to study using labeling methods.
Imaging of thin transparent multiple-scattered samples has been a difficult problem in optical imaging, in that multiple scattering creates an incoherent background that ultimately results in reduced image contrast, even for conventional quantitative phase imaging.
