Claim Text:
1. A stress detection device for a light-transmissive structure, comprising: a light source, a first polarizer, a light intensity distribution state detection unit, a stress distribution state analysis unit, and a real-time process parameter adjustment unit; wherein the light source emits uniform polarized light; during detection, the first polarizer and the light sources are located at opposite sides of the light-transmissive structure, respectively; the light intensity distribution state detection unit is configured to obtain a light intensity distribution state of the polarized light emitted from the first polarizer; the stress distribution state analysis unit is configured to obtain a stress distribution state of the light-transmissive structure according to the light intensity distribution state, wherein, the stress distribution state analysis unit is further used to analyze a reason why the light-transmissive structure has the stress distribution state, and wherein the real-time process parameter adjustment unit is configured to adjust various process parameters for manufacturing the light-transmissive structure in real time, based on the reason why the light-transmissive structure has the stress distribution state, which is analyzed by the stress distribution state analysis unit.
