Title:
THREE-DIMENSIONAL SCANNER AND PROBE
Document Type and Number:
WIPO Patent Application WO/2018/168635
Kind Code:
A1
Abstract:
Provided are: a three-dimensional scanner with which the state of a variable focus part can be accurately ascertained and a three-dimensional shape can be precisely acquired; and a probe. The present invention is a three-dimensional scanner that acquires shape information of a target object. The three-dimensional scanner comprises: a light source part (81); a variable focus part (82); a reference part (83); an optical path length adjustment part (84); an optical sensor (85); and a control unit. The variable focus part (82) is capable of changing a focal position, and light from the light source part (81) that reaches the optical sensor (85) through the target object (200) and light from the light source part (81) that reaches the optical sensor (85) through the reference part (83) both pass through the variable focus part (82) at least once. The control unit determines the state of the variable focus part (82) on the basis of light that is reflected in the reference part (83) and detected in a section of the optical sensor (85), and calculates, using information on the determined state of the variable focus part (82), shape information of the target object (200) from the light detected in the optical sensor (85).
