Controlling Ambient Illumination - Dalsa Z-Trak2 2K Series User Manual

Controlling Ambient Illumination

Over its image sensor window, the profiler uses a narrow bandpass optical filter that is tuned to the laser
wavelength (color) of the model. This allows the 3D sensor to be used in most ambient light conditions without
any measurement interference.
If the 3D sensor is used in a location with direct sunlight or any other type of bright full spectrum lighting, profiles
may distort due to interference with the laser emission. Bright ambient light of wavelength close to that of the laser
will pass through the 3D sensor filter and interfere with measurements.
Users need to control such ambient illumination conditions so that the laser line profiles are distinctly detected.
