A polarization analysis method based on a multi-parameter model is proposed to address the polarization effect analysis and calibration requirements of a dual-coded snapshot spectral polarization imaging system. A full-link polarization effect model for a spectral polarization imaging system is established that includes a digital micromirror array (DMD), prism grating prism (PGP), micro-polarizer array detector (MPA), and multi-film. The influence of parameters such as the refractive index, incident angle, grating refractive index, constant, prism refractive index, vertex angle, multi-layer film complex refractive index, and film thickness on the optical transmittance of the system are analyzed. Using a dynamic data exchange mechanism to perform full-link, full-FOV, and full-pupil ray tracing on the optical system, the polarization effect distribution of the system under different degrees of polarization (DOP) and wavelengths is obtained. A calibration experiment for the controllable incident wavelength and DOP using narrowband filters and glass stacks is established. The experimental results show that in the 420 nm, 532 nm, and 635 nm wavelength bands, the MSEs of the calibrated values are 1.3924 × 10−4, 1.6852 × 10−4, and 1.6735 × 10−4, respectively. It is proven that the calibration method based on a multi-parameter model is feasible. Finally, the spectral polarization image at 532 nm is calibrated. The contrast ratio of metallic aluminum is calibrated from 7.13 to 15.33. This study provides a theoretical basis for the analysis and calibration of polarization effects in a dual-coded snapshot spectral polarization imaging system.

The design of this light refractive index practicum tool aims to design and make developments from existing tools. This research uses the Borg and Gall method, which is limited to the initial development stage. In the first stage, researchers made field observations about this practicum tool and conducted literature studies to find references for tool design, namely determining materials. The second stage determines the components of the tool and makes a design in the form of a 3-dimensional image to determine the scale of the tool size. Furthermore, the third stage is the development of researchers realizing the design in the form of tool drawings into prototypes for laboratory scale trials and revising if there is still unstable data. After the data generated is stable, the tool is made according to the design with a size that matches the practicum tool until it is ready for a limited trial. The limitation of this research is because it is still in the laboratory scale trial stage to see the stability and accuracy of the data results on the tool.

“…In a review of physics, refractive index is the ability of light propagation of light through a substance in terms of the state of the molecules that make up the substance [7]. Measurement of the refractive index is important because it relates to physical parameters such as temperature, solution concentration, and others [8].…”

Refractive index practicum in sugar solution medium is carried out with the limitation of measuring the refractive angle of light using one type of solution, namely laboratory-scale sugar solution. The purpose of this study was to test the development of refractive index practicum tools for limited use with specifications of 10-watt lamps, 0°-90° arc scale, laser arc arm with a wavelength of 589 nm, laser chamber, vertical regulator position, limiting media in the form of glass and parallelogram-shaped solution cross-section. The variables used were solution concentrations in the 15% - 75% range and with incidence angles of 15°, 25°, and 35°, respectively. The results showed that the refractive index practicum tool has the advantage that it can be used more precisely both in light and darkness. The light used uses a laser with a wavelength of 549 nm and can measure the refractive index of a solution. The measurement results obtained the refractive index gradient value of the sugar solution at each concentration. The use of tools based on the processes science skills students in implementing activities practicum bias index in sugar solution.
