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

Figure 4

Image of test image and the detected photodiode image applying the 3D sensor system application (triangulation angle). The red square highlighted the object projection field. Due to the crosstalk effect the projection and detection fields have to be separated.

(a) Test image of the object field (projection path, diagonal 3 mm).

(b) Detected test image via the integrated photodiode matrix (PD) without optical elements (e.g., lens, mirror).

(c) Image of the detected test image in the labor setup (see Figure 5(b)) (detection path).
