An advanced thick film pressure transducer can be produced from an advanced thick film stack on a metallic substrate. A plurality of zones are formed as one group without prescribing the relationship between a zone and a group. In the logarithmic mode, the pixels are calibrated to remove fixed pattern noise. The present invention encompasses a method for producing stable, broadband, and low-coherent laser. This subtraction result, current detection value, and the rotor position from the position detection section are supplied to a current control section to carry out the current control operation so as to obtain a current command.
