研究目的
To develop a new method of polarimetry called 'ghost polarimetry' that extends the ghost imaging concept to polarization-sensitive objects, enabling the identification of the polarization structure of the object.
研究成果
The study demonstrates the possibility of determining the polarization state of an object using classical incoherent radiation, introducing a new method called ghost polarimetry. This method can be particularly useful when access to the object is limited, offering new opportunities in testing the state of biological tissues in vivo and other applications.
研究不足
The method requires the object to be illuminated by unpolarized incoherent light with Gaussian statistics. The spatial scale of polarization variation must be larger than the coherence radius of radiation for the simplified expressions to hold.
1：Experimental Design and Method Selection:
The study uses a theoretical model treating an object as a Jones matrix to analyze its polarization properties. The method involves measuring mutual correlation functions of currents in the object arm and two reference arms where signals in orthogonal polarizations are registered.
2：Sample Selection and Data Sources:
The object is illuminated by unpolarized incoherent light with Gaussian statistics. The polarization state of light is described by the Jones vector, and the object is characterized by the Jones matrix.
3：List of Experimental Equipment and Materials:
The setup includes a beamsplitter (BS), a polarizing beamsplitter (PBS), a bucket detector (BD), and multi-pixel detectors (D1, D2).
4：2).
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The light beam splits into two beams; one illuminates the object, and the other serves as a reference. The radiation after passing through the object is collected by a single-pixel detector, while the reference beam is split by the PBS and registered by multi-pixel detectors.
5：Data Analysis Methods:
The information on the polarization properties of the object is extracted from the correlation functions of the currents measured by the detectors.
