Paper Abstract

Pattern projection-based three-dimensional (3-D) measurement systems are well established in various application fields. However, for some time, there has been an increasing demand in terms of a higher measurement speed in order to analyze fast processes. We introduce a GOBO slide-based projector (GOes Before Optics) providing high speed, high radiant flux, and eye-safe incoherent light at low cost. We present its setup as well as the generation and change of the projected patterns. We explain the 3-D measurement principle and show first measurements of an inflating airbag and a rope skipper conducted at a 3-D frame rate of more than 1.3 kHz.
