Abstract: A method and system for the automated collection and storage of calibration data over the entire spectral and power range of an optical functional system having an optical functional device and a device controller. The automatic calibration test set-up of the invention includes a laser source, an optical power controlling device, and an optical multimeter that are stepped over the entire operating range of the optical functional device. Measurements are taken at the input and output to the device, and at the input and output to the device controller. The test set-up is coupled to a calibration workstation which, in turn, can be coupled to the controller of the optical system. Since the controller is based on a digital microprocessor, it is straightforward to programme the controller to store data or to execute particular algorithms as required by a given operational configuration.
