I. Plane MirrorsDielectric Coated Mirrors: These mirrors have multiple layers of dielectric coatings on the optical element surface, which enhance reflectivity through interference in a specific wavel...

The application of optical lenses in autonomous driving mainly includes the following aspects:LiDARLiDAR (Light Detection and Ranging) is one of the key sensors in autonomous vehicles, capable of prov...

2.2 Basic Polarization StatesA. Elliptical PolarizationElliptical polarization is the most fundamental polarization state. In this case, the two electric field components have a constant phase differe...

Optical Knowledge Sharing - Optical PolarizationPolarized light has three fundamental characteristics: wavelength, intensity, and polarization. The wavelength of light is easy to understand. For examp...

The day-night dual-pass filter, as an important optical component, is widely used in CCD and CMOS imaging systems, CCTV surveillance systems, and other fields. Its characteristic is that it can captur...

If an optical system converts a diverging spherical wave into a converging spherical wave, the system is referred to as a diffraction-limited system. In this case, the optical system has no aberration...

High damage threshold mirrors are crucial optical components designed to protect optical systems under high-power laser irradiation. They feature high reflectivity and a high damage threshold, effecti...

Common reflecting telescope systems are typically of the Newtonian or Cassegrain type. These telescopes use a concave mirror as the primary mirror to converge light and form an image, thereby avoiding...
