Summary:3-D imaging is an important technology for machine-environment interactions. The most promising approach for 3-D image is the time-of-flight approach where the distance is measured from the phase shift from the emitted and reflect light. To perform the correct sensing, a Photonic Demodulator is need. And the most common one is the Current -Assisted Photonic Demodulator (CAPD). While the device is there for a while, there is no compact model for it. In this work, a compact model for CAPD is presented to explain the interaction between optical and electrical signals.
