A new type of stress testing technology has been developed in the last 20 years by combining pixelated polarization cameras with traditional photoelastic methods. It overcomes the disadvantages of traditional photoelastic methods such as weak ability to resist environmental light interference, complex quantitative measurement operation, and difficulty in realizing real-time measurement. This paper introduced the working principle of this method and showed its great technical advantages in adapting to complex environments and high-precision testing through two examples. Some forward-looking application suggestions of the new photoelastic technology were given, including the efficient detection of the installation stress of the glass curtain wall and the online detection of the internal defects of the tempered glass.
