Abstract
The present invention relates to a device and a method for measuring an axial polarizing angle of a polarizer. The apparatus can have a to-be-measured polarizer disposed therein, and comprises a light generating device, a light polarizing device and a measurement comparison device. The light generating device provides a light source. The light polarizing device is disposed corresponding to the light generating device to load the to-be-measured polarizer, and measures a light signal after the light source passes through the to-be-measured polarizer without rotating the to-be-measured polarizer, and transforms it into readable data. The measurement comparison device is electrically connected with the light polarizing device and has at least one preset comparison data to receive the data provided by the light polarizing device and compare it with the comparison data. Thus, after comparing the data provided by the light polarizing device with the comparison data, an axial polarizing angle of the to-be-measured polarizer is quickly and accurately measured and calculated.
