我们在高光谱荧光显微镜上实现了无滤光片照明方案,以实现全范围光谱成像。显微镜采用偏振滤波,空间滤波和光谱解混滤波,以取代传统的过滤器的作用。在测量的荧光团发射光谱的信号动态范围和准确性的背景下,提供了全光谱显微镜和基于滤光片的显微镜之间的定量比较。为了显示潜在的应用,五色细胞免疫荧光成像实验进行了理论模拟。仿真结果表明,使用建议的全谱成像技术可能会导致三倍的信号动态范围的改善相比,可以实现在基于滤波器的成像。
We implement a filterless illumination scheme on a hyperspectral fluorescence microscope to achieve full-range spectral imaging. The microscope employs polarisation filtering, spatial filtering and spectral unmixing filtering to replace the role of traditional filters. Quantitative comparisons between full-spectrum and filter-based microscopy are provided in the context of signal dynamic range and accuracy of measured fluorophores’ emission spectra. To show potential applications, a five-colour cell immunofluorescence imaging experiment is theoretically simulated. Simulation results indicate that the use of proposed full-spectrum imaging technique may result in three times improvement in signal dynamic range compared to that can be achieved in the filter-based imaging.
