Abstract
A laser scanning device includes a laser device, a collimating lens, a scanning mirror, a telecentric lens, and a negative lens. The laser device emits a source light. The collimating lens is used to receive the source light and emits a first parallel light. The scanning mirror is used to receive the first parallel light and change a transmission direction of the first parallel light to emit a deflection light. The telecentric lens is used to receive the deflection light and deflect the deflection light into a second parallel light which is parallel to an optical axis of the telecentric lens. The negative lens is used to receive the second parallel light and emit a scanning light by changing a transmission direction of the second parallel light. A projecting system and a time of flight device are further disclosed.
