In total, four PCBs areimplemented in the camera. The boards are stacked onto each other. All boards havethe same dimensions, except the illumination Module.The four boards are named:• Illumination Module (ILM)• Sensor Head Module (SHM)• Image Processing Module (IPM)• Communication Interface Module USB (CIM-USB)The ILM contains 55 LEDs and their high-power driver electronics. It is directlyconnected to SH boards through a stacking socket. The SHM controls the sensors andconverts the raw sensor output signals into digital data values. The IPM processes thedata from the SH and performs the distance and amplitude calculation as well asadditional signal processing tasks.. The CIM-USB ensures the USB2.0 interface to thecomputer. Furthermore, it contains the power supplies.15
