摘要: Provided is an atomic force microscope capable of increasing the phase detection speed of a cantilever vibration. The cantilever (5) is excited and the cantilever (5) and a sample are relatively scanned. Displacement of the cantilever (5) is detected by a sensor. An oscillator (27) generates an excitation signal of the cantilever (5) and generates a reference wave signal having a frequency based on the excitation signal and a fixed phase. According to vibration of the cantilever (5), a trigger pulse generation circuit (41) generates a trigger pulse signal having a pulse position changing in accordance with the vibration of the cantilever (5). According to the reference wave signal and the trigger pulse signal, a phase signal generation circuit (43) generates a signal corresponding to the level of the reference wave signal at the pulse position as a phase signal of vibration of the cantilever (5). As the reference wave signal, a saw tooth wave is used. A phase signal generation circuit (43) is formed by a sample hold circuit.

摘要: A driving laser unit (11) irradiates a laser beam on a cantilever (5) to cause thermal expansion deformation. A driving-laser control unit (13) performs feedback control for the cantilever (5) by controlling intensity of the laser beam on the basis of displacement of the cantilever (5) detected by a sensor (9). A thermal-response compensating circuit (35) has a constitution equivalent to an inverse transfer function of a heat transfer function of the cantilever (5) and compensates for a delay in a thermal response of the cantilever (5) to the light irradiation. Moreover, the cantilever (5) may be excited by controlling the intensity of the laser beam. By controlling light intensity, a Q value of a lever resonance system is also controlled. It is possible to increase scanning speed of an atomic force microscope.

摘要: An imaging apparatus includes a solid-state imaging device and an imaging device driver. The imaging device includes first pixels and second pixels. The first pixels execute an imaging operation for a long exposure time. The second pixels execute an imaging operation for a short exposure time which overlaps with a part of the long exposure time. The first and second pixels are mixedly arranged in a two dimensional array. Plural different drive controlling modes each controlling operation timings of start and end of exposure of the first pixels and operation timings of start and end of exposure of the second pixels are prepared in advance. The imaging device driver selects one of the drive controlling modes in accordance with a shooting condition under which an object image is taken and drives the solid-state imaging device in accordance with the selected mode.
