    • An object information acquiring apparatus is used. This apparatus comprises: a light source configured to emit pulsed light of a plurality of wavelengths; a wavelength controller configured to switch the wavelength; a probe configured to receive an acoustic wave generated and propagated in an object subjected to the pulsed light emitted onto the object; a scan controller configured to move the probe within a predetermined scanning range; and an information processor configured to acquire information about the object by using a plurality of electric signals corresponding to the wavelengths of the pulsed light output from the probe at each reception position in the scanning area. The wavelength controller switches the wavelength of the pulsed light before the probe scans the entire scanning area while receiving at each reception position an acoustic wave corresponding to at least one of the wavelengths of the pulsed light.
    • 使用对象信息获取装置。 该装置包括:被配置为发射多个波长的脉冲光的光源; 波长控制器,被配置为切换波长; 探针,被配置为接收在经受发射到所述物体上的脉冲光的物体中产生和传播的声波; 扫描控制器,被配置为在预定扫描范围内移动所述探针; 以及信息处理器,被配置为通过使用与扫描区域中的每个接收位置处的从探测器输出的脉冲光的波长相对应的多个电信号来获取关于对象的信息。 波长控制器在探针扫描整个扫描区域之前切换脉冲光的波长,同时在每个接收位置接收与脉冲光的至少一个波长相对应的声波。

    • A sensor includes a detecting oscillator supported in such a manner that the detecting oscillator is allowed to oscillate; first and second electrodes; a detecting electrode facing the first and second electrodes; and signal supplying units configured to supply first and second AC signals respectively to the first and second electrodes. Either the first and second electrodes or the detecting electrode is provided on the detecting oscillator. The first and second AC signals respectively supplied to the first and second electrodes by the signal supplying units cause the detecting oscillator to be maintained at a neutral position for detection without being displaced when no physical quantity is input. When the detecting oscillator is displaced, an input physical quantity is detected on the basis of a signal corresponding to charges induced at the detecting electrode by the first and second AC signals supplied respectively to the first and second electrodes.
    • 传感器包括以允许检测振荡器振荡的方式支持的检测振荡器; 第一和第二电极; 面向所述第一和第二电极的检测电极; 以及信号供给单元,被配置为分别向第一和第二电极提供第一和第二AC信号。 第一和第二电极或检测电极都设置在检测振荡器上。 分别由信号提供单元提供给第一和第二电极的第一和第二AC信号使检测振荡器保持在中性位置用于检测,而不会在不输入物理量的情况下移位。 当检测振荡器移位时,基于分别提供给第一和第二电极的第一和第二AC信号,根据与在检测电极处感应的电荷相对应的信号来检测输入物理量。
