Imaging Result Because the sub-encoding aperture is about 0.30.3 mm, it also has function of small-hole Because the sub-encoding aperture isis about mm, additionally, it has thethe function of smallSince the sub-encoding aperture about 0.3 mm, it also has the function of smallhole imaging, the imaging is blurred, as shown in Figure 13. 13. imaging, but but the imaging isis blurred, as shown in Figure 13. hole imaging, but the imaging blurred, as shown in FigureSensors 2021, 21, FOR Sensors 2021, 21, x7757 PEER Review Sensors 2021, 21, x FOR PEER REVIEW10 of 12 10 ten of 12 ofFigure 13.

Multispectral coded aperture imaging method prototype acquisition information.A vital function ofofthemultispectral imaging method is istoaccurately receive An essential function ofthe multispectral imaging technique istotoaccurately obtain An essential function the multispectral imaging system accurately obtain spectral information. To verify the capability ofofthemultispectral imaging program totoobtain spectral details. To confirm the potential ofthe multispectral imaging program toobtain spectral information and facts. To verify the ability the multispectral imaging program get multispectral information, the color pattern isis projected onthe LED show. Soon after the information are multispectral data, the colour pattern is projected onthe LED show. After the information are multispectral information, the color pattern projected on the LED display. Right after the data are collected, R R (650 nm), G (550 nm), and(450 nm) three-band image composite color images collected, R(650 nm), G (550 nm), and B B (450 nm) three-band image composite colour imcollected, (650 nm), G (550 nm), and B (450 nm) three-band image composite color images obtained; if theif if the color is consistent using the image, it can be indicated that fairly are are obtained; colour colour is constant using the original image, it it can be indicated that ages are obtained; the is constant using the original original image, is indicated that reasonably accuratedata can information could be obtained. outcomes test results are shown in Figure 14. precise spectral spectral be obtained. The test The test outcomes are shown in Figure 14. somewhat accurate spectral data can be obtained. The are shown in Figure 14.(a)(a) (b)(b)(c)(c)(d) (d)Figure 14.
