Lasers and camera modules for the 'Saturn' 3D sensor
EVT has equipped the smart 3D sensor called 'Saturn' with its lasers. This results in a significantly more homogeneous laser line.
The lasers are available in all standard colors red, green, blue, violet. Depending on the object to be imaged, the right laser color can produce a significantly better artifact-free image.
The lasers are also available in different power levels from 0.5W to 10W, so that sufficient light output is available for all applications.
This is advantageous and necessary because, depending on the application, greater laser power has to be used, an example being tires. On their rubber, a large part of the light power is eliminated by the absorption of the surface. Therefore, more light must be used.
But even at high speeds, more light must be applied to the test object so that the laser line can be detected despite the short exposure time.
With the lasers, camera modules with faster sensors are also available. This increases the maximum frame rate and thus 3D lines per second from the previous 3KHz to 9KHz.
