Artificial Solar Lighting System for Evaluating LiDAR, Sensors, and Cameras that Support Automated Driving and ADAS Technologies

Artificial Solar Lighting System for Evaluating LiDAR, Sensors, and Cameras that Support Automated Driving and ADAS Technologies

Used successfully in a wide range of R&D and quality control applications for cameras, sensors, and other devices in the car electronics field!

Because this is artificial solar lighting that produces the same light as sunlight, with a wavelength band of 300 – 2500 nm that is one of the largest in the industry, it is possible to create environments that are extremely similar to the outdoors. As a result, it is possible to accurately reproduce situations such as sunlight shining into an interior through a window, the setting sun, backlighting, and reflected light.
