Simulation and System Design of a 3D Metrology Optical System Based on a Bidirectional OLED Microdisplay

Figure 8

Principle of the 3D sensor system. The pattern images (OLED-BiMiD/(a)) are projected via a projection lens onto the measurement object (e.g., sinusoidal MO) (b). Then the detector (PD-BiMiD/(d)) detects the image of the measurement object during fringe projection (c). For this part the detected image of (c) is used as image/light source and is imaged into the BiMiD detector plane that is shown in (e). The 3D model is calculated with an internal Fraunhofer IOF software. (a) OLED generated fringe pattern image, (b) 3D measurement object, (c) fringe projection on the measurement object, (d) detected image of the measurement object during fringe projection, and (e) reconstructed 3D object.
