摘要： The optical deflector includes a deflector, a vibration detector, a driving signal generator, a modulation timing signal generator, and a deflection detector. The deflector has a vibrational system having a movable body with a light deflecting member, and deflects light from a light source by the movable body. The vibration detector detects the vibration condition of the vibrational system of the deflector. The driving signal generator generates a driving signal for driving the vibrational system of the deflector. The modulation timing signal generator generates a modulation timing signal as the reference time for regulating the amount of light from the light source. The deflection detector detects the deflection condition of light deflected by the deflector. The driving signal generator generates the driving signal based on information of the vibration condition detected by the vibration detector, and the modulation timing signal generator generates the modulation timing signal based on information of the deflection condition detected by the deflection detector.

摘要： Provided is a control apparatus and control method for a capacitive electromechanical transducer with small decrease in transmission/reception efficiency, and with sets of transmission/reception characteristics with different frequency ranges. The apparatus has cells each including first and second electrodes facing each other via a gap; includes a driving/detecting unit and an external stress applying unit. The driving/detecting unit performs at least one of causing the second electrode to vibrate and transmit elastic waves by generating an AC electrostatic attractive force between the electrodes, and detecting a change of capacity between the electrodes, the change being caused by the second electrode vibrating upon receipt of elastic waves. The external stress applying unit changes the external stress applied to the second electrode. The driving/detecting unit adjusts frequency characteristics by changing a parameter defining the frequency domain used in a transmitting/receiving operation, corresponding to the change of the external stress.

摘要： A sensor includes a movably supported movable element and an opposing member, and sensor detects a relative positional relationship between the movable element and the opposing member which are provided with a spacing therebetween. The opposing member has an impurity-doped portion which is provided at either an opposing portion, which is opposed to the movable element, or an adjoining portion, which adjoins the opposing portion. At least a part of the impurity-doped portion is formed on an opposite surface (that is, opposite to a surface that faces the movable element), from which opposite surface an electrical wiring is led out.

摘要： There is a case in which a generated acoustic wave is decreased owing to the attenuation of light, whereby a desired output is not obtained from an electromechanical transducer device that receives the acoustic wave. The control apparatus for controlling an electromechanical transducer device of the present invention includes: a conversion unit that converts a current output from a first electrode of the electromechanical transducer device to a voltage; a DC voltage applying unit that applies a DC voltage to a second electrode arranged with a gap between itself and the first electrode; and a generation unit that generates a control signal which makes at least one of the DC voltage and a conversion ratio for converting the current to the voltage be changed, on the basis of information about an elapsed time from a point in time at which an inspection object was irradiated with light.
