    Abstract: A light irradiation device that emits a light patch of uniform intensity. The device may be a dental light wand. The device has a light source, a lenslet array and an optional relay lens. The light source may be a laser or a collimated LED. Each lenslet of the lenslet array has two convex surfaces, a front convex surface, and a rear convex surface that is opposite to the front convex surface. The front convex surface has a focal point on the principal plane of the rear convex surface. The focal length of the front convex surface differs from the focal length of the rear convex surface. Light beams emitted by the light source pass through the lenslet array, and if a relay lens is present then pass through the relay lens, forming a light patch of uniform intensity.

    Abstract translation: 发射均匀强度的光斑的光照射装置。 该装置可以是牙科灯棒。 该装置具有光源，小透镜阵列和可选的中继透镜。 光源可以是激光或准直的LED。 小透镜阵列的每个小透镜具有两个凸面，前凸面和与前凸面相反的后凸面。 前凸面在后凸面的主面上具有焦点。 前凸面的焦距与后凸面的焦距不同。 由光源发射的光束通过透镜阵列，如果存在中继透镜，则通过中继透镜，形成均匀强度的光斑。

    Abstract: A 3D imaging apparatus with enhanced depth of field to obtain electronic images of an object for use in generating a 3D digital model of the object. The apparatus includes a housing having mirrors positioned to receive an image from an object external to the housing and provide the image to an image sensor. The optical path between the object and the image sensor includes an aperture element having apertures for providing the image along multiple optical channels with a lens positioned within each of the optical channels. The apparatus also includes a transparent cover positioned within the optical path and having a plurality of fiducials. The depth of field of the apparatus includes the cover, allowing the fiducials to be used to calibrate the apparatus or verify and correct the existing calibration of it.
