  • Patent number: 9420246
    Abstract: A projection system includes a projection module, an infrared monitoring module, and a focusing device. Lights of a projection light source (100) pass through a light splitting element (500) and a first lens group (201), and then emit out; infrared lights from outside pass through the first lens group (201) and the light splitting element (500) to an infrared monitoring module (300). Only the first lens group (201) can move back and forth and a focusing device is provided for driving the first lens group (201) to move back and forth. Optical characteristics of a projection objective (200) and a monitoring objective ensure that, during moving of the first lens group (201) driven by the focusing device, the projection objective (200) focuses clearly, and an infrared monitoring image received by an induction chip (301) meets monitoring requirements synchronously.
