ToF: Understand Current Assisted Photonic Demodulator (CAPD)

Time of Flight technology works by measuring the time delay of light traveling from a light source, reflecting off a scene, and into a sensor. The specific type of Time of Flight the Sony IMX556 CMOS sensor uses is called continuous wave (CW) modulation, also known as CW phase-shift or Indirect Time of Flight. Instead of measuring the time delay of a single light pulse, the Helios…
