Title: PATTERNED LIGHT IRRADIATION APPARATUS AND METHOD
Abstract:
A patterned light irradiation apparatus is disclosed. The patterned light irradiation apparatus comprises a light source, a pattern grating, and a diaphragm, wherein the pattern grating includes a stripe shape in a form including repetition of a transmission part and a shielding part, and the diaphragm includes an aperture having a sinusoidal wave-shaped cross section. When the patterned light irradiation apparatus irradiates patterned light to a subject, the patterned light irradiation apparatus performs defocusing and thus can irradiate patterned light having an ideal sinusoidal form to the subject. Therefore, a three-dimensional image of high quality can be acquired.
