Classification: CPC G  H | IPC G

Claim 8:
9. A device for calibrating and monitoring a laser wavelength shift and the laser position displacement relative to a support,
wherein the device comprises
a pattern generator,
a camera,
one or several heat pumps,
one or several temperature sensors, and
a computer,

wherein the device is configurable to make the laser illuminate the pattern generator and enable the camera and computer to record several individual patterns, and a composite pattern containing those individual patterns, enable by means of the heat pump and temperature sensor to control and record the temperature of one or several of the laser, pattern generator, camera, and the support, comprising the means to calculate pattern position displacements between corresponding individual patterns from composite patterns, responsivity parameters of the camera and laser position displacement and laser wavelength shift, laser position displacement and laser wavelength shift by means of the responsivity parameters and displacements between corresponding individual patterns.
