研究目的
To develop a novel system for optical rotation measurement that overcomes the limitations of existing methods, such as small measurement range, non-real-time performance, low measurement accuracy and resolution.
研究成果
The proposed pixelated-polarization-camera-based polarimetry system (PPCBPS) overcomes the drawbacks of existing methods, offering real-time performance, wide measurement range, high accuracy, and high resolution. It shows great potential for applications in hospital clinical diagnosis, chemical research, sugar production, and the pharmaceutical industry.
研究不足
The measurement accuracy is affected by dust on the polarizer and unstable light intensity of the sodium light. The systematic errors vary linearly over a small range, and the actual performance could be higher with more accurate calibration methods.
1：Experimental Design and Method Selection:
The system employs pixelated polarization cameras and Stokes parameters to record and extract the polarization information of linearly polarized incident light.
2：Sample Selection and Data Sources:
The system is tested with sucrose solutions of varying concentrations to measure optical rotation.
3：List of Experimental Equipment and Materials:
Includes a pixelated polarization camera, laser source, integrating sphere, polarizer, and polariscope tube.
4：Experimental Procedures and Operational Workflow:
The linearly polarized light passes through the optically active substance, and the rotation of the polarization plane is recorded by the pixelated polarization camera.
5：Data Analysis Methods:
The algorithm based on Stokes parameters is used to calculate the optical rotation from the recorded images.
