Design of Optical System in Wide Range of Sugar Degree |
| |
| Abstract: | This paper designed a new optical system with two sources for measuring the sugar degree of solution based on critical angle. This system could improve the range of the measurement without changing the parameter of receiving image sensor, and guarantee the precision. The paper presented the prism size,distance between the two light sources,light-lens focal length and diameter, and other parameters of the optical structure by analyzing the optical pathway diagram based on formulas of refraction and reflection. And the system is validated by experiment. |
