A broadband superluminescence light source was coupled into a Michelson interferometer. The sample arm provides light to the microscope imaging system, while the reference arm is designed to have the same optical path length as the sample arm. Interference between the sample and reference arms is collected through a home-made spectrometer. Obj: objective lens, L: lens; SLD: superluminescence diode; M: mirror.
