Abstract

Within the scope of the Collaborative Research Centre (CRC) Transregio 73 (SFB/TR73) research project, a new kind of micro fringe projection system is being developed. By using flexible imaging fibre bundles, it becomes possible to collect complete data sets of filigree and hardly accessible assembly geometries. The talk presents the principle of the new kind of endoscopic micro fringe projection system and points out its certain advantages. It combines a laser light source with a Digital Mirror Device (DMD), image fiber and advanced micro optics. Thereby a 7.5 times increased depth of focus of 3 mm compared to 0.4 mm with common light sources could be achieved. Preliminary considerations of the optical design, simulation results and the consequential setup are as well shown as measurement results of the current system.
