The embodiments herein relate to methods for controlling an optical transition and the ending tint state of an optically switchable device, and optically switchable devices configured to perform such methods. In various embodiments, non-optical (e.g., electrical) feedback is used to help control an optical transition. The feedback may be used for a number of different purposes. In many implementations, the feedback is used to control an ongoing optical transition. In some embodiments a transfer function is used calibrate optical drive parameters to control the tinting state of optically switching devices.

There is provided a laser processing device that includes a laser light source configured to output laser light, a spatial light modulator configured to modulate the laser light output from the laser light source according to a phase pattern and emit the modulated laser light, an objective lens configured to converge the laser light emitted from the spatial light modulator onto an object, a controller configured to control a phase pattern to be displayed on the spatial light modulator, and a determiner configured to determine whether operation of the spatial light modulator is normal, in which the controller performs switching control in which the phase pattern to be displayed on the spatial light modulator is switched, and the determiner makes the determination on the basis of a change in intensity of the laser light emitted from the spatial light modulator between before the switching control and after the switching control.

A device may include a plurality of interferometers. The plurality of interferometers may include a parent interferometer, a first child interferometer coupled to a first branch of the parent interferometer, and a second child interferometer coupled to a second branch of the parent interferometer. At least one of the plurality of interferometers may be calibrated by maintaining collinearity of an output of the first branch and the second branch and using perturbation signals.

An exemplary embodiment provides a display device including: a display part configured to include a display part color filter; and a peripheral part disposed at the upper side of the display part and including an inspection pattern for checking an alignment of the display part color filter.
