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

Figure 6

Paraxial optical system setup of the 3D sensor. On the left-hand side a top view of the BiMiD is shown and on the right-hand side the paraxial lens setup is shown.The projection and detection fields are oriented to reach the best fill factor for the microdisplay. Due to this effect the display is rotated for the paraxial system simulation. Projection and detection fields are orientated perpendicular. At the paraxial lens setup the bi-directional OLED microdisplay is positioned on the left side and on the right side the measurement object (e.g., sinusoidal mirror element) is placed. The blue ray path describes the projection and the green one describes the imaging path.
