Abstract
An optical scanning apparatus for performing scanning by focusing a beam scattered by a bubble which moves at a predetermined speed within a closed loop fluid pipe, thereby forming an image. The optical scanning apparatus includes a light source for emitting light; a closed loop fluid pipe; a fluid contained in the fluid pipe, transmitting the light emitted from the light source; at least one bubble contained in the fluid pipe, scattering incident light; a pump installed at one side of the fluid pipe, circulating the bubble at a predetermined speed; and an image formation lens focusing the light emitted by the light source and scattered by the at least one bubble to form an image on a predetermined scanning line. Accordingly, the volume of the optical scanning apparatus can be reduced, and the optical scanning apparatus can be easily manufactured. Consequently, productivity can be increased.
