Resum: | The human eye is a complex dynamic system that undergoes fine rotations and deformations. Usually information about the eye globe deformation and micromovements are averaged and lost when using commercial measuring devices, although they provide important information about the eye’s physiology and the visual process. We have constructed a dynamic topographer from an existing Placido projection head and a video camera. The algorithms of calibration, data processing and topographic reconstruction are also explained in this paper. With our system, the CCD parameters and the algorithms can be controlled offering many possibilities for eye researchers. Obtained results show that the system is reliable for measuring eye dynamics. Some applications of the device are also outlined. |
