介绍作为行扫描摄象机照明器而设计的新式光学系统。该系统在平面上产生线性照明模式,并且采用塑料的菲涅耳(Fresnel)透镜以降低系统的成本,减小系统的体积。一个作用如一维漫射体的定做的光纤列阵是高数字孔径投影系统的一个部件,它能提供35°以上的照射半角锥。这种大范围的入射角使得表面成象可从近镜状一直到朗伯漫射体。
Introducing the new optical system designed as a line scan camera luminaire. The system produces linear illumination patterns on a flat surface, and uses plastic Fresnel lenses to reduce system costs and reduce system volume. A custom fiber array that functions as a one-dimensional diffuser is a part of a high-aperture digital projection system that provides a half-cone of illumination above 35 °. This wide range of angles of incidence allows the surface to be imaged from nearly mirror-like to the Lambertian diffuser.
