基于串联法布里-珀罗干涉仪（FPI）的多路复用技术，研制了傅里叶变换二维荧光激发光谱仪（FT-2DFES）。除了多路复用技术的优点之外，串联FPI的主要优点是适用于具有大吸收带宽（大于100 nm）的跃迁的调制，并且因此适用于凝聚相中分子的激发的调制。作为FT-2DFES有效性的证明，我们成功地分别观察到来自激光染料（香豆素480、罗丹明6 G、DCM（4-二氰基亚甲基-2-甲基-6-（p-（二甲氨基）苯乙烯基）-4H-吡喃）和LDS 750）的混合甲醇溶液的荧光激发峰。此外，还观察到了若丹明6 G与LDS 750之间的能量转移。
A Fourier transform two-dimensional fluorescence excitation spectrometer (FT-2DFES) was developed based on the multiplex technique using a tandem Fabry-Pérot interferometer (tandem FPI). In addition to the advantage of the multiplex technique, the main advantage of the tandem FPI is applicable to the modulation of transition with a large absorption bandwidth (larger than 100 nm) and is thus applicable to the modulation of the excitation of molecules in the condensed phase. As a demonstration of the effectiveness of FT-2DFES, we succeeded in separately observing the fluorescence excitation peaks from a mixed methanol solution of laser dyes (coumarin 480, rhodamine 6G, DCM (4-dicyanomethylene-2-methyl-6-(p-(dimethylamino)styryl)-4H-pyran), and LDS750). Furthermore, the energy transfer from rhodamine 6G to LDS750 was observed.
