Analysing lidar return signal strengths for target optical surfaces and atmospheric conditions

This article is brought to you by: 

Lidar systems are complex, dynamic devices involving both optical, mechanical, and electronic components that must work together while interacting reliably with a widely varying external environment. It is the optical part of the system that interacts with the environment, and so it is through optical modeling that we can gain a crucial insight into expected performance under varying conditions.

In this paper, we will take a brief look at how illumination ray tracing software can be used by engineers to gain these insights into expected lidar system performance before building expensive prototype systems.

High-Yield Optimization - Streamlining the path to more easily manufacturable designs

This article is brought to you by: 

The conventional optical design approach results in designs that are very sensitive to manufacturing and alignment errors, which means the optical product is difficult to repeatedly manufacture successfully.

A new method, called High-Yield Optimization, produces designs that meet tight performance specifications, provide a higher manufacturing yield, and lower manufacturing costs through less waste.
