The technological basis for the Triple-IN range of sensors, the 2D and 3D Time Of Flight laser sensors is the KEM method for time measurement. It results in an accurate compensation technique which gives results that are independent of temperature, reflectivity, and distance and applies an intelligent building block system.
With this we can offer a KEM sensor program with potential for development in our range of PR, PS, PAS, PC and PAC sensors.
KEM Sensors measure ranges and angles to distant objects and deliver through their interface
- range (1D),
- range profiles (2D) as a set of polar coordinates and
- range images (3D) as a set of spherical coordinates.
With the new KEM Technology the time between transmission of a laser pulse and receipt of an Echo-Pulse as TOF (time-of-flight) is evaluated. From the TOFs the ranges to reflecting object points are derived.
The KEM Method delivers two essential advantages:
- In an Array of time measurement channels many TOFs can be measured simultaneously. This parallel measurement allows a significant increase of the measurement speed of a sensor.
- By evaluation of pulse sequences of up to 500 pulses for each measurement many echoes and many noise pulses are measured. When averaging single measurements, the mean value of noise tends to zero whereas the signal pulses remain. This allows an increase of sensitivity of up to 100 in regards to other types of flight time measurements.
Because of the extensive and diverse applications of the KEM Technology in 2D and 3D KEM sensors, Triple-IN has developed as a basis for product development a modular hardware and software system and base sensors.
With this modular building block system development projects of customer-specific sensors may be carried out safely and quickly.
To ensure technical success Triple-IN has developed simulation models that allow prediction of the technical data of planned sensors.
