Abstract: There is provided an ophthalmologic apparatus which can be effectively used for the clinic of a dry eye by using, as a basic principle, that when a tear film dries up, a corneal shape is changed and/or a wavefront aberration becomes large. When a measurement is started, the ophthalmologic apparatus is aligned. An arithmetic part performs an initial setting of a measurement interval of the apparatus, a measurement time and the like by a wavefront measurement part. An input part or the arithmetic part triggers a measurement start, and the arithmetic part repeats a measurement of the corneal shape and corneal wavefront aberrations by a measurement part until time reaches a measurement end time. When the time reaches the measurement end time, a judgment part analyzes a breakup state as one index for judgment of a state of a dry eye. The judgment part obtains values relating to the breakup to output them, and performs an automatic diagnosis about dry eye on the basis of the values.

Abstract: A device for detecting asynchronization or stepping out of a stepping motor without making the stepping motor large in size. Parallel resonance circuit LC is provided in a recovery circuit of stator coil RL of the stepping motor for detecting linking current IX. If the stepping motor is out of step, the magnetic resistance between stator and rotor increases while the reactance of stator coil RL decreases. When motor drive current ID is turned off, a large transient current is momentarily generated yet is quickly dampened. While the motor drive current ID is off, linking current IX approaches zero. Consequently, if the stepping motor is out of step, there is no substantial difference in the linking current IX when motor drive current ID is turned on from when motor drive current ID was off. Also, the amplitude of the transient or resonance waveform is smaller than the amplitude when the stepping motor is operating normally.
