AI Technical Summary
Traditional laser scanning units suffer from problems such as long optical back cutoff, large device size, and large space occupation when scanning large areas, making it difficult to meet the requirements of miniaturization.
A catadioptric laser scanning unit is adopted. By designing a catadioptric optical path between the first and second lenses, the light beam is reflected twice in a limited space. Combined with the curved optical surface design, the light beam is effectively folded, shortening the optical path.
It achieves a compact structure for the laser scanning unit under the same scanning area, ensuring uniform density and clarity of the scanned image, reducing equipment costs, and is suitable for traditional imaging devices and additive or subtractive manufacturing equipment.
