Improved Experimental System for Analyzing Biomechanical Properties of Iris Tissue
We designed a experimental system based on stereo vision in order to analyze quantificationally biomechanical properties of iris tissue without destroying the structure and function of iris.This experimental system,which was designed and improved upon the primary experimental device,consists of three vidicons assembled with tripod,a circular desk scaled from one degree to 360 degrees,a signal generator,a special lamp-house,a pupil-blocking simulating device,a negative pressure device,a constant temperature trough assembled with a fixed bracket,a load-pressure trough and a small electric elevator.The new experimental system could simulate the pupil-blocking phenomena.The animal research was proved that the results were consistent with the clinical observation.The new experimental system could also obtain continuous pressure data and corresponding 2D image of iris from three different degrees in the course of load-pressure.The experimental system not only is an ideal experimental system to measure biomechanical properties of iris tissue and pupilblocking force quantitatively,but also can be used to research small distortion characteristic of other biologic material.
