| titleOfInvention | System and method for dynamic contact angle measurement |
| abstract | A system and method for dynamic contact angle measurement on a curved material are disclosed. One embodiment of the method comprises: initializing a video-based contact angle measuring apparatus; preparing the curved material for contact angle measurement; performing a sessile drop procedure to deposit a drop of liquid on the curved material; capturing an image of the drop on the curved material at a preset time; determining a drop-curved material interface on the image; determining a drop profile on the image; and calculating a set of dynamic contact angles based on the drop-curved material interface and the drop profile. The contact angle measuring apparatus can further comprise a processor for executing software instructions, a software module comprising processor-executable software instructions for performing at least some of the steps of the method and a memory, operably coupled to the processor, for storing the processor-executable software instructions. Further, the steps of determining the drop-curved material interface, determining the drop profile, capturing an image, initializing the contact angle-measuring apparatus and calculating the set of dynamic contact angles can each be at least partially performed via software running on the processor. The contact angle measuring apparatus can also include a camera and a digital frame-grabber for capturing an image. As a further aspect of the present invention, the curved material can be a hydrogel contact lens either mounted on an external sample stage or in a patient's eye for in vivo contact angle measurements. |
