Abstract: An ophthalmologic apparatus includes an examination optical system, drive part, two or more imaging parts, analyzer, storage, position corrector, and controller. The examination optical system examines an eye. The drive part moves the examination optical system. The imaging parts substantially simultaneously photograph the anterior segment of the eye from different directions.

The storage stores correction information in advance. The correction information is acquired based on optical properties of eyeballs, and used to correct the position of the eye in the optical axis direction of the examination optical system. The position corrector corrects the three-dimensional position obtained by the analyzer based on the correction information.

Abstract: Light with a short pulse width is emitted using a simple structure. A light source 101, a differentiation circuit 102, and a switch 103 are connected in series. When the switch 103 is switched on, inrush current flows in a capacitor 102b forming the differentiation circuit 102, and accordingly the light source 101 is supplied with electric current and thereby emits light. When the capacitor 102b is charged, electric current flows in a resistor 102a, and voltage drops at the resistor 102a. Then, the voltage applied to the light source 101 is decreased, whereby the light source 101 stops emitting light. The values of the resistor 102a and the capacitor 102b are adjusted so that the above phenomenon occurs.
