FAQ - Frequently Asked Questions

Yes. Blickfeld LiDAR sensors meet laser safety class 1 according to the the IEC 60825-1:2014 standard limits. The sensors are not dangerous under reasonably foreseeable conditions.

The Cube is operated with a 12 V power supply (10 – 26 V absolute minimum – maximum values).

The Cube’s housing consists of black anodized aluminum, and the window of the sensor is made of acrylic.

The Cube 1 can be purchased in an outdoor version that is waterproof and resistant to dust. More information.

Highly reflective surfaces are easy for the sensor to detect at any distance.

For highly absorbent surfaces, the reference value of 10% reflectivity is compared. The performance of Blickfeld sensors at 10% reflectivity can be found in the datasheet.

The Cube measures a maximum of 270 000 points per second.

The angular distance between points horizontally can be adjusted between 0.4° and 1.0°. Vertically, you can set the angular distance indirectly by the number of scan lines. With a max. 30° vertical field of view and 500 scan lines, you will get a distance of approx. 30/500 ~ 0.06°.

The Blickfeld Scanner Library (BSL) is used to integrate the Blickfeld Cube into existing environments. Currently, native implementations of the BSL exist in C++, and Python.

Detailed documentation of the BSL and more information can be found here:

Data overhead for Blickfeld sensors can be 1-3 Mbyte/s, so a 4G or 5G network is preferable to a LoRaWAN network.

The Cube has IP40 protection as standard and is IP65-rated in the outdoor version.

The data rate depends on the number of detected echoes, however, maximum values can be specified.

For Cube 1, for example, a maximum of 6 MB/s applies with one evaluated echo per sampled point. With three evaluated echoes, the maximum data rate can reach up to 8 MB/s. Using the Blickfeld Scanner Library, the data stream can be customized to meet individual requirements such that only the relevant data is transmitted, which optimizes the data rate.

Furthermore, the smart background subtraction can reduce the data rate to a few kB/s in favorable cases.
