能够用于生物物理研究的椭圆偏振仪是80年代初期问世的,由于它具有方法简便、数据可靠、重复性好且精度高等优点,一出现便受到研究肌肉收缩机制的生物物理学家的青睐,但长期来,它的测试速度一直没有能够突破,使其应用受到局限。通过几年的探索,我们从理论到实践首次成功地利用磁光晶体为核心元件,采用调制法,使测试速度提高了三个数量级,可以获得几十毫秒量级变化的动态信息。结合快速付立叶变换和多元线性回归软件对采集的信息进行数据处理,减小了使用硬件不可避免的测量误差,使仪器的测试精度又有长足的提高,这无疑对一些生物和化学反应动力学机制的研究会有新的推动。
The ellipsometer that can be used in biophysical research was introduced in the early 1980s. It is favored by biophysicists who study the mechanism of muscle contraction due to its advantages of simple method, reliable data, good repeatability and high precision. But over the long term, its testing speed has not been able to break through, so that its application is limited. After several years of exploration, we successfully used the magneto-optic crystal as the core component from theory to practice for the first time. By adopting the modulation method, we improved the test speed by three orders of magnitude and obtained the dynamic information of tens of milliseconds in magnitude. Combined with fast pay-Fourier transform and multiple linear regression software for data processing of the collected information to reduce the use of hardware unavoidable measurement error, so that the accuracy of the test instrument has greatly improved, which undoubtedly for some biological and chemical reaction power Research on the mechanism of learning will be a new impetus.
