A surface-emitting laser diode capable of being manufactured easily at low cost, and capable of stabilizing the polarization direction of laser light in one direction and achieving higher output is provided. The systems and methods analyze an image to determine its texture moments. A first coating material web runs from the first web supply, along the media path through the fuser, to the first web take-up and a second coating material web runs from the second web supply, along the media path through the fuser, to the second web take-up. It is possible to obtain a piezoelectric device which is capable of improving the adhesion property of both the piezoelectricity layer and the electrode layer and reducing a basic point voltage fluctuation at the time of high-temperature operation so as to improve reliability.
