Investigation on diffraction efficiency of BOE for beam shaping

More Information
  • Received Date: November 02, 1998
  • Revised Date: December 11, 1998
  • Published Date: January 24, 2000
  • A binary optical element which is designed to convert a single-mode He-Ne laser beam into a ring-shaped intensity distribution is investigated experimentally. The measured diffraction efficiency are compared with numerical calculation when the distance between BOE and the output plane is changed.
