The LDL-T Laser Rangefinder Sensor Module is a compact, high-accuracy laser distance measurement module designed for industrial automation, robotics, smart devices, and precision measurement systems.
Built on advanced phase-shift iToF (indirect Time of Flight) technology, ЛПНП-Т delivers millimeter-level accuracy, stable performance, and flexible system integration in a lightweight form factor.
High-Accuracy Laser Rangefinder Sensor Based on iToF Technology
Unlike traditional ultrasonic or low-resolution optical sensors, the LDL-T Laser Rangefinder Sensor Module uses phase-based iToF laser ranging. By analyzing the phase difference between emitted and reflected modulated laser signals, the sensor calculates distance with exceptional precision.
Key benefits of iToF laser ranging:
-
Millimeter-level measurement resolution
-
Strong resistance to ambient light interference
-
Excellent repeatability and signal stability
-
Ideal for short-to-medium range precision measurement
This makes the LDL-T Laser Rangefinder Sensor Module especially suitable for applications requiring high accuracy and compact integration.
