High speed measurement with a maximum sampling frequency of 100Hz
Excellent anti-ambient light usability (operable under 100kLux ambient light)
Protection grade reaches IP65
Anti-corrosive against pesticide
Small in size and light
Major Applications
Drone altitude holding and terrain following
Machine control and safety sensors
Distance measuring instrument
1.Optical Principle
TOF is short for Time of Flight. It refers to that a sensor emits modulated near infrared light, which reflects when objects are in the way. TOF then converts the distance away from the filmed scenery by calculating the time difference or phase difference between emission and reflection, thereby generating in-depth information.

1 The reflectivity of black standard board is 10%. And the reflectivity of white standard board is 90%.
2 The testing environment is indoor white standard board.
4.Detection Angle
TF02's signal acceptance angle is 3˚, so LiDAR's detection angle is 3˚. The side lengths of different distance detection ranges (the detection range takes on a square shape) are shown as below in the table.
