摘要：PURPOSE: A two-dimensional optical scanning apparatus is provided to obtain a small size by using a polygonal rotating mirror extended in a longitudinal direction like a linear light source, and enable two-dimensional scanning without rotating the polygonal rotating mirror at high speed, thereby reducing power consumption and noise. CONSTITUTION: A two-dimensional optical scanning apparatus includes a linear light source(100) having a plurality of light-emitting devices(110) arranged in a longitudinal direction to emit modulated light for transmission of video information, a collimator lens(200) changing light emitted from the light-emitting devices of the linear light source to parallel beam, and a scanning means having a polygonal rotating mirror(300) extended in a longitudinal direction, the polygonal rotating mirror having a rotational axis arranged in parallel to the longitudinal direction of the light source.
