Abstract: An anti-twist structure of a voice coil motor includes a base, a lens housing, a first elastic sheet, a second elastic sheet, a magnet, and a yoke member. The lens housing has first margin wall and a second margin wall, and a first protrusion extends from the first margin wall. The height of the second protrusion is lower than the height of the first protrusion. The yoke member has a first wall, a connection wall, a second wall, and a side wall. The first wall is disposed above the first protrusion, and the second wall is disposed above the second protrusion. The lens housing has a deflectable angle relative to a horizontal reference line. When the lens housing deflects to a maximum value of the deflectable angle, the first margin wall abuts against the second wall and/or the first protrusion abuts against the first wall.

Abstract: A light source is used to project a structured light pattern onto a transparent piece under test. A first image sensing unit is used to obtain first image information of the structured light pattern on the transparent piece under test. A second image sensing unit is used to obtain second image information of the structured light pattern on the transparent piece under test. A processing unit includes a memory unit and a computing unit. The memory unit is used to store a correction parameter set, and the computing unit is used to receive the first image information and the second image information and obtain three-dimensional information of a surface of the transparent piece under test through the correction parameter set.

Abstract: The anti-twist structure includes a base, a lens housing, an elastic sheet and a yoke member. The lens housing has a margin wall with a first protrusion, a second protrusion and a contact portion. The contact portion is extended outwardly the first protrusion, and the second protrusion is protruded from the contact portion. The first protrusion and the second protrusion are protruded along an axial direction substantially perpendicular to the margin wall. The elastic sheet is disposed on the contact portion. When the lens housing deflects from the horizontal reference line to a maximum value of the deflectable angle, the first protrusion abuts against an upper wall of the yoke member, the second protrusion abuts against the elastic sheet, and the contact portion abuts against the elastic sheet or the upper wall at the same time, whereby the lens housing and the yoke member interfere with each other.
