Abstract
A system for determining the surface structure of an object, the system comprising a first assembly including an illumination source, and a binary mask to generate a binary pattern, the binary mask disposed between the illumination source and a defocusing element to modify the binary pattern to provide a continuously modulated fringe pattern to illuminate the surface of the object.
Claims14
A system for determining the surface structure of an object, the system comprising a first assembly including:
- an illumination source;
- and
- a binary mask to generate a binary pattern, the binary mask disposed between the illumination source and a defocusing element to modify the binary pattern to provide a continuously modulated fringe pattern to illuminate the surface of the object.
A method for determining a surface structure of an object, the method comprising:
- generating a binary pattern using a binary mask to be illuminated using an illumination source;
- illuminating the surface of the object with a continuously modulated fringe pattern generated by modifying the binary pattern using a defocusing element.
