Polarization imaging method and device thereof, and polarization imaging system

Abstract

The embodiment of the invention discloses a polarization imaging method and a device thereof, and a polarization imaging system. In the polarization imaging method, through changing the position of anaperture light hole, polarized transmitted beams in different angle ranges and / or in different directions after a collecting lens pass through the aperture light hole, multiple first polarization properties of a standard sample and multiple second polarization properties of a to-be-tested sample are acquired, multiple polarization property errors are obtained by the multiple first polarization properties of the standard sample and the standard properties of the standard sample, and thus, after the multiple second polarization properties of the to-be-tested sample in different angles are acquired, the multiple second polarization properties in different angles are calibrated by the polarization property errors, on the premise of reducing the polarization property errors of the acquired multiple second polarization properties, the resolution of the polarization image of the to-be-tested sample is improved, the anisotropy information of the to-be-tested sample is acquired, and the polarization imaging method is simple and the cost is low.

technical field [0001] Embodiments of the present invention relate to the technical field of polarization imaging, and in particular, to a polarization imaging method and device thereof, and a polarization imaging system. Background technique [0002] Polarization imaging technology is an advanced characterization method. Its basic principle is to obtain part or all of the polarization state information of the measured light by measuring the different polarization components of the light, and analyze and calculate these polarization information images to obtain polarization Parametric images, such as polarization degree, polarization angle, ellipticity angle, polarization transmission characteristics, depolarization characteristics, etc., are used to analyze the shape, roughness, medium characteristics and even biochemical characteristics of the measured object.

Problems solved by technology

However, in the actual polarization imaging process, the incident light on the object side of the collecting lens is not all parallel light, and there are some non-parallel light at a certain angle with the optical axis of the collecting lens. The existence of the non-parallel light will introduce detection errors; And when improving the resolution of polarization imaging, it is necessary to increase the diameter of the collection lens or reduce the focal length of the collection lens to increase the numerical aperture of the collection lens, which will further increase the error of polarization imaging
