Abstract
Disclosed are an optical fiber scanner and a projection apparatus. The optical fiber scanner comprises a housing, an optical fiber enclosed in the housing, an actuator, and projection objective lenses, wherein the optical fiber comprises a fiber core and an inner cladding; the optical fiber is fixed on the actuator, one end of the optical fiber extends beyond the actuator to form an optical fiber cantilever, and a fiber core end face of the optical fiber cantilever is recessed inwards to form a negative focal power, such that an equivalent light-emitting surface of the fiber core end face is reversely focused in the fiber core; and the projection objective lenses are arranged on a light-emitting path of the optical fiber cantilever and are used for focusing and imaging the equivalent light-emitting surface ().
