“…It indicates that the eggshell quality of SO egg (Egg 1) is significantly higher than that of GO egg (Egg 2) and Egg 3 normal egg. Referring to the optical illuminance simulation and optical density analysis methods [27], a correction was applied to the data visualization analysis and statistical technologies to analyze the distribution of gray-scale density values of eggs of three different qualities (Gd = Gv/Gu, grayscale density = count matrix of grayscale unit/grayscale Figure 7A shows a comparison of the shell-quality curves of eggs of three different qualities. The distribution of gray-scale values of the SO egg (Egg 1) is significantly larger than that of the GO egg (Egg 2) and normal egg (Egg 3).…”

Digital radiography is currently the main method of medical imaging diagnosis. It also has a wide range of applications across different fields. This study used radiation to conduct non-destructive visual imaging, and further established a quantitative analysis for visual gray-scale images to determine changes in the quality of eggs. Eggs of the same weight with three quality classes were chosen according to the egg labels available on the market. Furthermore, a general medical X-ray digital imaging system was used to apply two-dimensional digital radiography. A photometric interpretation of monochrome gray-scale imaging established by the Digital Imaging and Communications in Medicine (DICOM) standard was used to conduct a quantitative stratification analysis of the matrix data visualization, along with one-way analysis of variance (ANOVA) for quantitative statistics of the gray-scale values for the three structures, i.e., shell, air cell, and yolk. The statistical results showed that X-ray digital gray-scale images and a quantitative stratification analysis of the matrix data visualization results are less easily identified based on visual differences. In the quantitative statistical results of the one-way ANOVA gray-scale values, the whole-egg and in-egg quantitative matrix analysis both show p < 0.05. In the analysis of egg freshness, the quantitative statistics of the percentage of space occupied by the air cell in the eggs also showed p < 0.05. In addition, the results of the freshness of each egg were graded. The quality and freshness of the eggs can be quantitatively analyzed through radiographic imaging. The results of this study will provide a more scientific and quantitative reference for the quality and freshness of agricultural products in the future.

“…The Monte Carlo ray-tracing method has been widely used to calculate the performance of optical systems, and it belongs to a simplified physical model-based bidirectional reflection distribution function rendering [14,15]. In this paper, we conduct ray-tracing simulations with some adaptations to analyze the arrangement of optical devices for PSP measurement using TracePro7.03, which is non-sequential ray-tracing software from Lambda Research Corporation that has been widely applied in optical field simulation analysis and optical layout design [16][17][18].…”

Pressure sensitive paint (PSP) technique have shown their superiorities in the capability of large coverage area and high spatial resolution. The process of PSP technique usually requires sufficient illumination that covers the entire test object and camera that acquires the particular excited fluorescence. Applications on internal flow study like compressor cascade may fail as the optical access is heavily limited due to the closely adjacent components, which puts forward a high demand for spatial positioning arrangement of optical devices in the visualization system. In this work, a pre-positioning method was proposed to help determine the arrangement of optical devices of internal flow PSP measurement system in advance. And it was applied to the measurement for a linear compressor cascade with large solidity. The results showed that with the optical layout arrangement determined using this pre-positioning method, a full-field pressure distribution of cascade blade can be acquired successfully.

In this study, we introduce a novel design of a remote edge-lit backlight structure featuring blue laser diodes (LDs). These LDs were integrated into a remote yellow phosphor layer on a light guide plate (LGP). Blue light emitted by the LDs passes through the LGP and spreads to the remote phosphor layer, generating white light output. Owing to the incorporation of a scattering layer between sequential LGPs, the remote edge-lit backlight structure facilitates the expansion of the output surface of the LGP by combining multiple individual LGPs. Two- and three-LGP remote edge-lit backlight structures demonstrated acceptable white illuminance uniformity. The proposed architecture serves as a viable solution for achieving uniform illumination in planar lighting systems using blue LDs; thus, this structure is particularly suitable for linear lighting or slender backlighting instead of display stand applications.
