Optical scanning apparatus |
摘要 |
An optical scanning apparatus having at least one f-theta lens positioned on a rotary device. A collimated light beam is refracted to produce a linear scan by the rotation of the f-theta lens by the rotary device. By not using a rotary polygonal mirror, the optical scanning apparatus has the advantages of better tolerance, less optical parts, easy assembly, low production cost and compact structure.
