Those utilization for method and the device and eye internal pressure measurement in order to detect the native mode of the vibration of the eye with laser interference method

摘要

In order to form the Fabry Perot cavity where the eye (3) being joint with this device vis-a-vis the detection device (1), as it possesses the main optical axis (A1), one side inside that is formed by the permanent echo component (M1), another side inside that is constituted the cornea of the eye by (2), has the reflecting interface of two both sides, it is positioned. In order in the aforementioned cavity, the incident laser beam (F), the center to be decided in the aforementioned main optical axis (A1) of the aforementioned Fabry Perot cavity, it is introduced, the aforementioned cornea (2) in order to obtain longitudinal direction interference between the traffic laser beams which are reflected with the reflected face to face of the aforementioned two of the aforementioned cavity, the alignment is done in side direction and longitudinal direction vis-a-vis the aforementioned main optical axis (A1), the optical electronic detector (7) is used in order to detect strength (i) of the aforementioned interference as function of time. It can apply to the measurement of the eye internal pressure this invention.
