Title:
UNIAXIAL CRYSTAL-BASED PHASE CONTRAST MICROSCOPY MODULE, DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/130636
Kind Code:
A1
Abstract:
Disclosed are a uniaxial crystal-based phase contrast microscopy module, device and method. The module comprises: a first polarizing plate, a second polarizing plate, and a uniaxial crystal arranged therebetween. Polarization states of the first polarizing plate and the second polarizing plate are orthogonal or parallel. The first polarizing plate is used for converting incident light carrying information of an object to be detected into linearly polarized light; the uniaxial crystal is used for enabling, on the basis of a photonic spin Hall effect and/or an angular dispersion effect, left-handed circularly polarized light and right-handed circularly polarized light generated by the linearly polarized light to generate displacements in opposite directions; and the second polarizing plate is used for performing sum or difference operation on a left-handed circularly polarized light field and a right-handed circularly polarized light field, so that when the displacements of the left-handed circularly polarized light and the right-handed circularly polarized light are much less than a spot size, a transmitted light field thereof is a first-order differential of the original incident light field. The present method can be used for edge enhancement of object strength information and visualization of object phase information. Compared with a traditional phase contrast microscopy technology, the present invention is more visual, convenient and time-saving.
