Abstract
The eye is positioned relative to a detection device in such a manner as to co-operate with the device to form a Fabry-Perot cavity having a main optical axis and comprising two opposite reflecting faces on the main optical axis, one of these two faces being constituted by a stationary reflecting element and the other being formed by the cornea of the eye. An incident laser beam is injected into said cavity so as to be centered on the main optical axis of the Fabry-Perot cavity, the cornea is aligned laterally and longitudinally relative to the main optical axis in such a manner as to obtain longitudinal interference between the go and the return laser beams reflected between the two reflecting faces of the cavity, and an optoelectronic detector is used to detect the intensity I of said interference as a function of time. The invention is applicable to measuring intraocular pressure.
