  • Structured light generating device and measuring system and method
    Patent number: 10105906
    Abstract: A structured light generating device and a measuring system and method are provided. The structured light generating device includes: a light modulating element for receiving a projection light beam and modulating the projection light beam into a first structured light beam having a pattern, and a light shifting element corresponding to the light modulating element for receiving and shifting the first structured light beam to generate a second structured light beam having the pattern. A shift difference is formed between the first structured light beam and the second structured light beam, and the first structured light beam and the second structured light beam are superimposed to form a superimposed structured light beam so as to improve resolution.
