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。

Three important conclusions are achieved: 1 By analyzing the demand for spatial resolution of recording medium in different digital holographic recording setups, it shows that lensless Fourier transform holography can relax the requirement of spatial resolution and use the full spatial bandwidth of the CCD sensor. 2 Because of the differences of spatial resolution of image planes in different directions, reconstructed images can be relatively extended in the direction of high spatial resolution and reduced in the direction of the low one. 3 Lateral resolution of the reconstructed images is mainly determined by the highest spatial frequency of digital holograms recorded by CCD, and increases with the larger CCD size, the higher spatial resolution of the CCD sensor, and the shorter recording distance.

通过分析几种不同数字全息记录光路对记录介质空间分辨率的要求表明，无透镜傅里叶变换全息光路对CCD的空间分辨率要求最低，最能充分利用CCD的带宽；再现像面的空间分辨率在不同方向上的不一致，会导致再现像在空间分辨率高的方向上相对展宽，而在空间分辨率低的方向上相对压缩；再现像的横向分辨率主要由CCD所能记录的物体的最高空间频率决定，它随CCD的尺寸和空间分辨率的提高及记录距离D的减小而提高。

There are more advantages in holographic grating than in nicking grating such as no optical spectrum,no ghost line,high resolution ratio and so on.

全息光栅与刻痕光栅相比有着更多的优点，如光谱中无鬼线、杂散光少、分辨率高等，因此，全息术成了制作光栅的首选方法，其中光路的选用在制作过程中就尤为重要了，但现有的制作方法选用的光路却不是很恰当，为此，对其进行了改进。
