查询词典 focalize

To obtain precise result, itis necessary, in the aspect of hardware, to set up one stable optics system with highSNR, only if so, can we do the measurement with the steady NIR. To do so, we designthe optics system using AOTF, and take some measures to increase the light energyand the system SNR, which includes the three layers structure of the light chamber,the equipments to cover the useless light, polarizing to reduce the influence of 0 gradelight and focalize the light with lens. Apart from the hardware aspect, according to theexperiments, we can see that the different temperatures between at setting up themodels and at predicting the results will affect the prediction results in a way, and theaffection extent will be increased along with the increase of the temperaturedifference. Moreover, the light energy that can be detected will be different with thecontact pressure, and the match of the refractive indexes between the tissue and thesurroundings will enhance the light transmission depth, which will take moreinformation of the tissue. So, during the measurement, we should ensure the sametemperature between measuring and predicting, the same contact pressure at everymeasurement and the match of the indexes between the tissue and the surroundings aspossible as we can.

要提高测量精度，从硬件方面就必须有一个稳定的、信噪比较高的分光光路系统，以此得到稳定的近红外光来进行无创检测，针对这个目的，我们设计了 AOTF 分光光路系统，并在系统中采用一定的措施如三层灯室结构、遮光筒以减小杂散光、起偏和检偏来减小 0 级光影响、透镜汇聚等等来提高出射光的能量和系统的信噪比；从其他影响因素方面，通过实验，我们得到不同的建模温度对于预测结果有一定的影响，且影响随着温度的差值越大而越大，另外散反射光谱的能量也随着接触压力的不同而不同，组织的折射率与环境匹配将加大光的入射深度，从而能携带更多的组织信息，所以在测量时我们尽可能保证同一温度、保证同一接触压力以及利用物理或者化学的方法使组织与环境折射率匹配等。
