The latest lidar products for 2022

A look at the market for lidar and some of the systems, products and solutions available

Light detection and ranging (lidar), is a remote sensing method that uses the pulse from a laser to collect measurements. These are used to create 3D models and maps of objects and environments. A typical lidar sensor emits pulsed light waves into the surrounding environment, which bounce off surrounding objects and return to the sensor. The sensor uses the time between each pulse leaving and returning to calculate the distance it travelled. This process must be repeated millions of times per second for a real-time 3D map of the environment to be produced.

The first recorded lidar-like system was introduced by the Hughes Aircraft Company, led by physicist Malcolm Stitch. The system combined laser-focused imaging with the ability to calculate distances by measuring the time for a signal to return using appropriate sensors and data acquisition electronics. Some of the first applications for lidar were in meteorology. For example, the National Center for Atmospheric Research used it to measure clouds and pollution. In 1971, it gained even more prominence when astronauts on the Apollo 15 mission used a laser altimeter to map the surface of the moon.

 In more recent years, advancements in lidar have opened up more markets, such as defence, corridor mapping and topographical survey, automotive, mining, oil and gas, and consumer electronics, which are increasing the market scope of the lidar market. According to the latest market report from Grand View Research, the global lidar market size was valued at $1.81bn in 2021 and it is expected to expand at a compound annual growth rate (CAGR) of 9.8 per cent from 2022 to 2030.
