A method and apparatus for performing optical microscopy in one to three dimensions employs a spectral self-interference fluorescent microscopy technique that includes providing at least one fluorescent microscopy sample (220a, 220b), at least one objective lens (201), and a reflecting surface (204). The fluorescent sample is disposed between the objective lens and the reflecting surface, the distance (d1, d2) from the sample to the reflecting surface is several to several tens times an excitation wavelength. Excitation light (216) causes the fluorescent sample to emit light (214), at least a portion (214b) of which is reflected by the reflecting surface. The objective lens collects both the reflected light and the light emitted directly by the fluorescent sample (214a). The direct and reflected light interferences causing spectral oscillations in the emission spectrum. The periodicity and the peak wavelengths of the emission spectrum are then spectroscopically analyzed to determine the optical path length between the fluorescent sample and the reflecting surface.
