Simulation and System Design of a 3D Metrology Optical System Based on a Bidirectional OLED Microdisplay
Figure 5
Paraxial lens design and laboratory setup of the function test of an 3D sensor system. On the left-hand side the bi-directional OLED microdisplay is positioned. The projection path is folded by a fold mirror. The imaging path is unfolded. Both optical system magnifications are approximately . The diagonal of the projection and imaging field is 3 mm. At first the object field is projected into the measurement field, and then the illuminated measurement field is imaged onto the bi-directional microdisplay (detection plane).
