Then the dot projector shines more than 30,000 pin-points of light onto the face, building a depth map that can be read by the infrared camera. The flood illuminator shines infrared light at the face, which allows the system to detect whoever is in front of the iPhone, even in low-light situations or if the person is wearing glasses (or a hat). This includes an infrared camera, a flood illuminator, a regular camera and a dot projector. iPhone models supporting Face ID houses a variety of sensors, including the new True Depth camera system. ![]() ![]() The iPhone X and later models use structured light 3D sensing for facial recognition. Apple first implemented 3D sensing in its iPhone X in 2017.
