You might be aware of rangefinders but do you know what a short-range laser rangefinder is?
Let’s find out.
What Is Short Range 270 Scanning Laser Rangefinder?
A laser range finder measures distances accurately with high angular resolutions. However, the short range scanners need additional calibrations to reach the desired accuracy.
The calibration procedure described here allows for estimating the internal parameters of the sensor without using any special 3D targets.

Features
The UST-05LA has a convenient USB and serial port interface for setting up three different area output settings.
It relies solely on batteries for its operation over long periods of time.
With a 270° field of view up to five metres, the UST-05L LA Lidar scanner is truly unmatched.
Specifications
- A two-dimensional (2D) scanner for measuring distances from the sensor to its surrounding objects.
- Supply voltage ranges from 10 to 30 volts.
- It’s the smallest and lightest of any similar product.
- Measurement distance: five meters
- Faster response time: 66 milliseconds
- Flexible field settings are available
Operation
A UST-05LX/UST-05LN/UST-05LA is a handheld scanner for measuring distances up to 5 meters. It emits pulsed lasers around 270° field
When the emitted laser beam hits an obstacle, its distance is measured using the time-of-flight (TOF) principle, which measures the time taken for the light pulse to travel between the emitter and receiver.
The sensor has 521 measurements with a 1° pitch. You can set up to 31 area patterns.
Each area has three outputs.
- Output1
- Output2
- Output3
If the user presses the button, the output switches to the off state. To get the measurement value, the user must use the UST-05LA communication protocol.
