Lidar systems determine the distance of objects by targeting it with a laser and measuring the time for the reflected light to return to the receiver.
Lidar systems are reliant on very sensitive optical devices which need to be integrated together to create sophisticated imaging and sensing for a wide range of applications.
Distributed acoustic sensing
Lidar systems are divided into two categories: sensing within a fiber (distributed acoustic sensing) and atmospheric sensing. Distributed acoustic sensing (DAS) uses the fiber itself as the sensing element and provides information about the strain, vibration, temperature, and functionality of a fiber, as well as detecting pressure or other disturbances in the surrounding environment.
DAS systems are used for a wide range of applications, including but not limited to perimeter detection, oil wells, seismic sensing, monitoring traffic, and optical time-domain reflectometry (OTDR).
Atmospheric sensing sends light signals through the air and returns information about the reflected surface as well as the environment between the lidar system and the object. These optical sensing systems give information about the topography, position, and speed (due to the doppler shift).
Atmosphere sensing can be used for wind mapping for optimizing power generation from turbines, surveying planet surfaces, high precision manufacturing, preservation and restoration, environmental monitoring, measuring the wake of aircraft in airports, and space applications.
How we work in lidar and sensing
We design and manufacture LIDAR systems, subsystems, and modules for customers at all technology readiness levels (TRL). Flexible to all your lidar requirements and with a broad portfolio of components, we can provide single components, multiple components, a complete system, or multiple systems.
We pair our optical, mechanical, and electronic design capabilities with IP security and control, using our components or 3rd party components, to deliver at any point in the supply chain.
The more we are involved with the design and procurement, the more we are able to streamline the process and leverage our complete vertical integration, resulting in cost-effective and time-critical delivery of lidar components and systems. This also lightens the load of finding high-quality components for the entire system and allows us to help you make your design applicable for high-volume manufacturing of lidar systems.
With decades of experience working with customers in many sectors and for a broad variety of applications, we are an ideal partner for design for manufacturing, and customization of components, and have advanced, modern productions facilities in the UK and USA.
