激光透镜系统核心原理与应用分析（第二部分）

Laser lenses have extremely wide applications, mainly reflected in the following aspects:

- Function: Utilisé pour la perception environnementale et la modélisation 3D dans des domaines tels que la conduite autonome, la robotique et la cartographie topographique.

- Role of Lenses: Emit specific laser patterns (e.g., line lasers, area-array lasers) and receive the returned optical signals. The lenses here need to be highly precise to accurately control the field of view, resolution, and ranging accuracy.

- Function: Aplicado en el reconocimiento de Face ID en teléfonos móviles, escaneo 3D, juegos de detección de movimiento (por ejemplo, Kinect) e inspección industrial.

- Role of Lenses: The core component is the Diffractive Optical Element (DOE), which diffracts a single laser beam into a complex pattern (structured light) composed of tens of thousands of speckles and projects it onto the object surface. The 3D contour of the object is calculated by capturing the deformed pattern through a camera.

- Function: Servir como fuentes de visualización en televisores láser, proyectores láser y gafas AR/VR.

- Rôle des lentilles : Combiner, homogénéiser et scanner les faisceaux laser RGB à trois couleurs, ou les moduler via des puces d'affichage micro (par exemple, DLP, LCoS), puis projeter des images haute définition à travers des lentilles de projection. Les sources lumineuses laser présentent l'avantage d'une large gamme de couleurs et d'une haute luminosité.

- Function: 用于激光切割、焊接、标记、雕刻、清洗等。

- Role of Lenses: Focusing lenses concentrate the energy of high-power lasers into micron-level light spots, generating extremely high energy density for material processing. There are also red indicator light lenses for positioning.

- Function: 应用于激光指示器、武器瞄准镜和建筑激光水平仪。

- Role of Lenses: Mainly collimating lenses, which generate a clear light spot or crosshair visible at long distances.
