1991年12月,航空航天部科学技术研究院在我院主持了“调制光束全息术”的技术成果鉴定。鉴定专家组认为,由我院物理教研室教师蔡云良提出的“调制光束全息术”是一种以光调制理论为基础的独特的光测力学新技术。具有很高的实用价值,属国际首创。其理论和测试方法可以解决在较宽松的环境和设备条件下,任意形状表面物体的三维位移和位移方向的正确测量问题,并创造性地描述了记录光束受到光路元件运动调制时的全息干涉图的光强结构,建立了与调制干涉图组相对应的三维静位场的定量数学分析法和解调法;在对调制干涉条纹
In December 1991, the Institute of Science and Technology of the Ministry of Aeronautics and Astronautics presided over the technical achievement appraisal of “modulated beam holography” in our hospital. Accreditation expert panel believes that the “Modulation Beam Holography” proposed by Cai Yunliang, a faculty member of Physics Department of our college, is a unique new photometric technique based on light modulation theory. Has a high practical value, is an international initiative. The theory and test methods can solve the problem of correctly measuring the three-dimensional displacements and displacements of arbitrary shaped surface objects under the loosening environment and equipment conditions, and creatively describe the problem of the holographic interference pattern when the recording beam is modulated by the movement of the optical path element Light intensity structure, the quantitative mathematical analysis method and the demodulation method of the three-dimensional static field corresponding to the modulation interferogram group are established. After modulating the interference fringes
