摘要
针对等厚干涉-牛顿环实验,在读数显微镜中安装了红外反射式光耦报警系统,使实验者在寻找牛顿环的过程中一旦视觉感官被完全占用,报警器即发出"嘀、嘀"报警声从听觉感官上对操作者做出相应警示,从而避免了因违规操作而损坏仪器,也使其在读数显微镜的目镜视场中更容易找到牛顿环条纹,便于进行数据测量及计算。文章通过检测反射式红外报警装置的有效报警距离和灵敏度,将其很好地应用在读数显微镜上,具有广泛的实用价值。
In the equal thickness interferometer experiment of Newton＇s ring, infrared warning device is applied in reading microscope. The infrared warning device can warn operators by sense of hearing from damaging experimental equipments for disoperation if operators ＂sense of sight is occupied in seeking interference fringes of Newtons ring. And using wanting device, operators can find the interfer- ence fringes more easily in order to measure and calculate dates. With detecting out the effective distance and sensitivity shift of infra- red warning system, the device has been well applied in reading microscope with widespread practicability.
