Micro-optics system for non-rotational scanning comprising a plurality of micro-optical elements having different inclination patterns

A micro-optics system for non-rotational scanning, the micro-optics system comprising a plurality of micro-optical elements having different inclination patterns, wherein

• the plurality of micro-optical elements are classified into three zones,
• a first zone among the three zones includes a first micro-optical element that is included in the plurality of micro-optical elements and that includes a first inclination pattern such that a plurality of light rays incident from a light source are refracted in a range of 1 to 15 degrees from a center,
• a second zone among the three zones includes a second micro-optical element that is included in the plurality of micro-optical elements and that includes a second inclination pattern such that the plurality of incident light rays are refracted in a range of 16 to 30 degrees from the center, and
• a third zone among the three zones includes a third micro-optical element that is included in the plurality of micro-optical elements and that includes a third inclination pattern such that the plurality of incident light rays are refracted in a range of 31 to 45 degrees from the center.

A micro-optics system for non-rotational scanning, the micro-optics system comprising:

• a first micro-optical element including a first surface and a second surface;
• a second micro-optical element including a third surface and a fourth surface;
• and
• a third micro-optical element including a fifth surface and a sixth surface,
• wherein
• the first surface is flat,
• the second surface includes a first region, a second region, and a third region arranged with respect to a center,
• each of the first region, the second region, and the third region includes a first inclination pattern implemented such that a plurality of light rays incident from a light source are refracted in a range of 1 to 15 degrees in an outward direction from the center,
• light incident from the center is not refracted,
• the third surface includes a fourth region, a fifth region, and a sixth region that face the first region, the second region, and the third region, respectively,
• the fourth region is flat,
• each of the fifth region and the sixth region includes a second inclination pattern implemented such that the light refracted through the second region and the third region is refracted in a range of 16 to 30 degrees,
• the fifth surface includes a seventh region, an eighth region, and a ninth region that correspond to the fourth region, the fifth region, and the sixth region, respectively,
• the seventh region is flat,
• the eighth region and the ninth region include an inclination pattern, and
• the fifth surface includes a third inclination pattern implemented such that the light refracted through the sixth region is refracted in a range of 31 to 45 degrees.
