摘要 确定组织工程角膜透明度的测量方法,开发一套能实时测量组织工程角膜透明度的仪器。根据光学的基本原理,以虚拟软件为开发平台,采用计算机,数据采集卡,照度传感器等器件,确定并开发一种检测组织工程角膜透明度的方法与装置,通过对不同光源和被测样品进行检测,评价组织工程角膜透明度测量仪的精度。在确定组织工程角膜透明度测量方法的基础上,完成了基于虚拟仪器技术构建组织工程角膜透明度测量仪器开发,针对可见光、红色激光、有机玻璃、普法玻璃、隐形眼镜和猪角膜的测量计算,确定组织工程角膜透明度测量仪的系统误差修正值为0009 4,精度误差为06%〖DK〗~10%。本研究的组织工程角膜透明度测量方法与仪器可以对组织工程角膜进行定量的检测,比目前使用的方法更科学和方便,有望成为组织工程角膜度透明度测量的新标准;采用红色激光光源测量的角膜透明度比普通可见光测得的值有细微不同;但是对于确定的光源,该仪器不影响被测组织工程角膜透明度的优劣评比;更换不同波长光源,可以获得该种波长情况下角膜透明度的精确值。
