摘　　要：设计了一种测量生物分子信息的新型装置,该装置包括激光光源、柱面透镜、光阑、矩形聚合物凹凸光栅、数据采集系统和数据处理系统;激光经过柱面透镜扩束,再通过聚合物凹凸光栅时产生衍射图样;实验中用CCD采集了光栅衍射图样;利用计算机软件处理,得到1级和0级的衍射效率比,测出聚合物凹凸光栅的深度和光栅中葡萄糖溶液的深度;结果发现测量值与实际值在误差范围内相等。This paper designs a new kind of device for measuring bio‐molecular information ,which is com‐posed of laser light source ,cylindrical lens ,diaphragm ,rectangle polymer concave‐convex optical grating , data acquisition system ,and data processing system .Laser is expanded through cylindrical lens ,and then generates diffraction patterns through rectangle polymer concave‐convex optical grating .In the experi‐ment ,CCD adopts the optical grating diffraction pattern through computer software processing .The paper obtains the diffraction efficiency ratio of Level 1 and 0 .It measures the depths of rectangle polymer con‐cave‐convex optical grating ;and glucose liquid in the optical grating .T he findings show that the measured value is equal to the actual value within the error scope .
