METHOD AND APPARATUS FOR DETERMINING DYNAMIC DEFORMATION CHARACTERISTICS OF AN OBJECT |
摘要 |
Apparatus and methods for measuring a dynamic deformation characteristic of a deformable target surface during a deformation interval. The measurement principles may be applied to a large variety of organic and inorganic materials having a surface that can be deformed by an applied non-contact force. The surface may be light diffusing and non-transparent or non-diffusing and transparent. A device for measuring a dynamic deformation characteristic of an in-vivo cornea during a deformation interval includes a corneal topographer and an air puff generator that are operationally integrated. Use of the inventive device enables a method for making a measurement of a deformation characteristic of the in-vivo cornea during a deformation interval, further allowing a determination of spatially-resolved in-vivo corneal biomechanical and biodynamic properties such as corneal elasticity and corneal viscosity.
