To implement light quantity monitoring with high frequency responsivity and correction of astigmatic differences of a semiconductor laser with a simple configuration with fewer parts. Additionally provided is a process for applying the multi-component composite coatings described above to a substrate. The invention relates especially but not exclusively to a diverter assembly connected to a wing branch of a tree. If the communication terminal receives the deactivation authentication code while the secure device is attached to it, the secure device is deactivated. Being executed in all the pixels at the same timing, these operations play the role of the electronic shutter. A GPU program, that can be loaded and executed by a GPU, is obtained and encrypted to create an encrypted GPU program.
