      Time of Flight (ToF) is a distance measurement method. The modulated near-infrared light emitted from sensor is reflected by the object. By calculating the time difference or phase difference between emission and reflection, the distance from the object can be deduced and so does the depth information.

      (1)What is the spread of the laser beam?

      At very close distance (<0.5m), the beam diameter is about the size of the aperture of the lens. For distance larger than 0.5m, the beam diameter can be estimated using the following equation:

      distance / 20 = beam diameter at the this distance

      The actual spread is ~52 milli-radians or ~3 degree.

      (2)How do distance, target size, aspect, and reflectivity affect returned signal strength?

      The device transmits a focused IR beam that reflects off a target, among which a portion of which returns to the receiver. The distance between the device and the target is determined by the difference between the moment of signal transmission to the moment of signal reception. The effective reception of a reflected signal is influenced by, but not limited to, the following factors:

      • Target distance

        Returned signal strength ~ 1/D2

        D: distance

      • Target size

        Returned signal strength ~ 1/C4

        C: cross section of a target

      • Aspect

        The orientation of the target to the sensor influences the observable cross section. 

      • Reflectivity

        The reflective characteristics of the surface of the target influence the amount of returned signal.

      Generally, it is difficult to detect a small target, especially when it is distant, poorly reflective, and its aspect is away from the normal. Nevertheless, the returned signal strength can be improved by attaching an IR reflector to the target, enlarging the size of the target, modifying its orientation, or reducing its distance from the sensor.

      (3)How does the device work with different reflective surfaces?

      Generally speaking, the reflective characteristics of the surface of an object can be dedvided into threee categories: diffuse reflective, specular and retro-reflective.

      • Diffuse reflective surface

        For surfaces of materials like paper, matte walls and granite, their textured quality results in the uniform dispersion of reflected energy. Therefore the reflected energy of the dispersed laser is relaatively predictable in percentage. As a result, these materials can be read very well.


      • Specular surface

        For specular surfaces, only a small amout or even none of the reflected light reaaches the receiver, depending on the smoothness of the surface and the observation angle. The suggestion is to view the object from the normal.

      Questions and Answers

      Where I can find the Linux or Android driver for this LiDAR? The official Web-site ( provides the driver only for TE01 and it is not opensource.

      it looks(from above) to be just serial comms. no driver reqd. maybe the driver is for some other mode of comms...

      I checked their website. They have a program using this LiDAR. And they also provide serial and CAN protocol so that we can input the data via any program. I tested it on Matlab and Mathematica. Looks Great!

      Why is this called a LiDAR? Looks more like an accurate range finder. I could turn it into a LiDAR with servo scanning?

      Lidar means "Light Detection and Ranging" but is generally used by devices using a TOF mechanism. This indicates it is TOF. So the term Lidar seems legit IMHO.You might mean Lidar scanner. which is what you'd have to make with this and a servo or rotating mirror assembly (faster, more stable)I too wanted a lidar scanner. This device has update rate of 500Hz which is probably its maximum sampling rate. Therefore work out how far you can rotate it and sample at 500Hz to get the field you want to scan.500Hz (500 samples per second) isnt bad.It also has a maxobject detect of 4cm at 5m and range is 30cm to 10m.So it looks like it might make a low res low speed scanning lidar but frankly its hard to tell. The question is - is it worth the gamble for the money ? Its your money...

      sample rate indicated at 500Hz or 500 samples per second. I presume this is a max rate.
