Demonstrating the Working Principle of Flash LiDAR
Abstract
Nowadays, LiDAR technology has been applied in not only the professional areas but also in the consumer products. As an example, the flash LiDAR is found of great use in the smart devices because of their capability of fast and accurate 3D distance detection and measurement. In this example, we demonstrate the working principle of a typical flash LiDAR, which is composed of an array of sources, collimation lens system, and diffractive grating as beam splitter. Analysis is done in both the spatial and the spatial frequency domains.

Use Case
Demonstration of the Functional Principle of a Dot Projector
This Use Cases shows the working principle of a dot projector, including a comparision between an idealized and real design of a diffractive beam splitter.
Use Case
Design of 2D Non-Paraxial Beam-Splitting Metagrating
We design a 2D metagrating for beam splitting. The metagrating is constructed, analyzed, and further optimized in VirtualLab Fusion, especially in terms of the uniformity of the diffraction efficiencies.
