Measuring LEDs and lasers for near infrared sensing applications

Near-infrared light provides a new invisible interface for our equipment.Led High Bay Lights Most remote sensing systems in consumer electronics use near-infrared light for lighting, time-of-flight (TOF) and pattern analysis, so that facial recognition, gesture control, proximity sensing, and object mapping can be performed. Near-infrared light sources and cameras are rapidly being integrated into new products, especially for sensing within the human field of vision, which has increased the importance of characterizing the characteristics of the light source during the design and manufacturing process.

In order to ensure the performance of light beyond the visible spectrum of humans and the safety of the human eye, manufacturers must measure the intensity of the light beams and patterns produced by near-infrared LEDs and lasers. However, traditional light source measurement methods cannot meet the mass production needs of devices such as smartphones and extended reality (XR) headsets. The challenge requires a measurement solution that must be fast, easy to deploy, and practical for online testing.
