“…The request on the beam length and depth of focus can be met with dedicated optics. There have been studies [1][2][3][4] and commercial solution for the line beam shaper, which could be adopted for small optical devices such as dental or intra-oral scanning device. In this paper, a solution using on-the-shelf optics has been proposed, and the architecture can easily accommodate to varied specification of beam length and DOF.…”

This paper describes an optical system as the line beam shaper for an intra-oral scanning device. The line beam shaper needs to provide desired beam quality, including bean length, uniformity, line width and depth of focus while maintaining compact form factor. More specifically, the proposed optical system was demonstrated to use only the on-the-shelf lens element to resolve all the optical performance issue, and to lead to a versatile solution for varied specification.

“…For microscopy in the visible spectrum, Köhler illumination which provides uniform illumination plays an important role [ 1 ]. Besides microscopy [ 2 , 3 ], uniform illumination has also been applicated in fields such as lithography [ 4 ], inertial confinement fusion [ 5 ], laser processing [ 6 ], compact antenna test range [ 7 ], and so on [ 8 ]. The flattened Gaussian beam which has a flat-top spatial profile was introduced by Gori [ 9 ].…”

“…This method to make the uniform and sharp-edged beam has the advantage of high energy efficiency due to having no energy loss theoretically. 1 The output beam profile of the beam homogenizer is not significantly affected by the input beam condition such as size, shape, and distribution. 2,3 Recently, the optimization research of the beam homogenizer have been performed to improve the output beam quality.…”

Abstract. We proposed a zoom homogenizer that can control the size of the illumination field by adding one lens array to the conventional imaging-type beam homogenizer. An equivalent lens system was used to derive the imaging condition and size of the illumination field. The result of the ray-tracing simulation shows the validity of the zoom homogenizer to generate the uniform and sharp-edged beam. We presented the strengths and weaknesses of the zoom homogenizer in terms of its etendue with the maximum acceptance angle of the system. © The Authors.
