Problems solved by technology

The increase in the number of compound eye small units will lead to a very low compound eye processing yield and a sharp increase in cost
Due to the small amount of expansion of the laser, in order to obtain a good dodging effect, the size of each small compound eye unit needs to be made small when using the compound eye dodging device. Therefore, when the number of lasers is large, the small unit of the compound eye dodging device Increased quantity, resulting in lower compound eye yield and increased cost
If the number of units is reduced for a compound eye device with a large unit, the uniform light effect will be deteriorated, and the thickness of the compound eye will increase. After reaching a certain thickness value, the compound eye molding quality will be poor, the yield rate will be low, and the cost will increase.
Therefore, when the spot area is large, it is difficult to make a trade-off between the number, thickness and uniformity of the compound eyes
Therefore, the spliced ​​spot size needs to be compressed as much as possible, which results in many compression optics and a large spatial volume
If the spot area is reduced by increasing the compression ratio of the positive and negative lenses, the spot angle will be too large, so that under the premise that the light output angle of the compound eye remains unchanged, side lobes are prone to appear, and the energy utilization efficiency is reduced
