ABSTRACT:
There is disclosed a pulse-width controller which includes a first pulse-width adjusting section which adjusts the pulse width of a main pulse signal, a second pulse-width adjusting section which adjusts the pulse width of a reference pulse signal, a pulse-width measurement section which measures the pulse width of the reference pulse signal adjusted by the second pulse-width adjusting section, a target pulse-width setting section for setting a target pulse width to be achieved by the first pulse-width adjusting section, and a control section which outputs to the first pulse-width adjusting section a control signal for use in adjusting the pulse width of the main pulse signal in the first pulse-width adjusting section, on the basis of pulse-width information regarding the reference pulse signal measured in the pulse-width measurement section and the target pulse-width information set by the target pulse-width setting section. It becomes possible to precisely control a pulse width without being affected by the ambient state at the time of pulse-width control operations.
