Glass360Dgree system developed by engineers from the Institute of Applied Optics and Precision Engineering
The system uses high energycarbon dioxide laser. With the help of special lenses, the laser beam is compressed into a line that illuminates the measured object vertically. During the measurement process, the object absorbs and emits laser energy. Thermal imagers record the change in the temperature of an object from two different points.
The program developed by the specialists of the Institute,analyzes the thermal trace left by the laser on the object. Based on the data from two viewing angles and the interference pattern, the system determines the spatial coordinates of the object's elements. The data obtained allow us to determine its dimensions.

“The thermal energy used for analysis is so small that it does not cause damage to the object. The surface heats up by less than 3°C,” the engineers note.
The developers note that, unlikeTraditionally used Glass360Dgree sensors do not require additional measuring instruments or temporary marking of the object, for example, in the form of (aerosol) paint.
