Abstract
This letter describes the spectroscopic measurements of fluorescently stained cells. Variable phase-contrast fluorescence spectrometry was used on fluorescently stained cells to achieve high two-dimensional spatial resolution. Phase shift interferometry by autocorrelation interference made it possible to measure fluorescence spectra in the field of view without the separation of wavelengths, as in the case of a conventional dispersive spectrometer. In this letter, the authors describe the experimental characteristics of fluorescence spectra generated from fluorescently stained cells and verify that the fluorescence spectra of the stained area in the cells can be measured by our method.
