LDK 520nm Green Distance Laser Sensor<\/strong><\/h2>\n

Phase-Based Distance Measurement | 520nm Green Laser Wavelength<\/h3>\n

The LDK 520nm Green Distance Laser Sensor adopts the phase-based distance measurement<\/strong> principle, calculating the exact distance to a target by analyzing the phase shift of the modulated laser signal. Compared to traditional Time-of-Flight (ToF) methods, phase-based measurement provides higher accuracy and stability<\/strong> for short-range applications. Additionally, the sensor utilizes a 520nm green laser<\/strong>, which offers better performance than infrared or red lasers in bright environments, making it ideal for outdoor and reflective surfaces.<\/p>\n
