Development of Microscopic Super-Parallel Spectral Imager and Data Processing System

我们总结了我们在这个项目中取得的成就如下。我们构建了一个高光谱分辨率的光谱成像系统，并对成像系统中的Wolf效应进行了实验研究。我们成功地验证了我们的理论预测的沃尔夫效应在成像系统中的边缘形障碍。我们在第一年未能构建机械稳定的系统，但在第二年成功地提高了光谱成像系统中光路扫描器的位置控制精度。我们实现了0.3 nm的位置精度和3.86 cm-1的光谱分辨率<-1>。观测到的沃尔夫效应的光谱位移约为400 cm <-1>^2。我们成功地构建了一个50 × 50像素、40个光谱通道的超并行光谱成像系统，并将其应用于快速旋转物体的快速光谱测量。利用9 × 9透镜阵列从多幅具有不同光程差的干涉图图像中获得快速光谱。该物体连接到大约以1800 rpm旋转的轴上。在频闪照明的帮助下，本系统捕获了物体的清晰光谱图像。对光谱成像系统的噪声性能进行了理论分析，并对本系统的信噪比进行了实验研究.由于时间的限制，我们不能将本系统应用于显微成像，然而，在将预设系统应用于显微系统中时，预计没有问题。

We summarize our achievements in this project in the following.1. We constructed a spectral imaging system with high spectral resolution and investigated experimentally the Wolf effect in an imaging system. We succeed in verifying our theoretical prediction of the Wolf effect in an imaging system with an edge-shaped obstruction. We failed in construction of a mechanically stable system in the first year, but succeeded in improving the accuracy of position control of the optical path scanner in the spectral imaging system in the next year. We achieved the position accuracy of 0.3 nm and spectral resolution of 3.86 cm^<-1>. The observed spectral shift of the Wolf effect was approximately 400 cm^<-1>.2. We succeeded in construction of a super-parallel spectral imaging system with 50x50 pixels and 40 spectral channels and application to fast spectrometry of fast-rotating object. The fast spectroscopy is realized by the 9x9 array of lenses that from the multiple of interferogram images that have different path differences. The object was attached to a shaft that rotates approximately at 1800 rpm. With the help of a single shot of stroboscopic illumination, a clear spectral image of the object was captured by the present system.3. We analyzed theoretically the noise performance of the spectral imaging system and investigated experimentally the signal-to-noise ration of the present system.4. Due to the time-limitation, we could not apply the present system to microscopic imaging, yet no problem is expected in application of the preset system to microscopic systems.
