The expander and collimator optical system is configured to convert a light beam from the light source into a parallel light beam. The adjustable aperture is configured to adjust a diameter of the parallel light beam. The light beam with the diameter adjusted by the adjustable aperture is incident perpendicularly onto the binary phase grating, followed by the variable-focus optical system. The filter is positioned on a back focal plane of the variable-focus optical system, and is configured to receive a ring light source. The ring radius and radial width of the light source are adjustable by adjusting a focus length f1 of the variable-focus optical system. |
