Abstract :
This paper shows the viability of using inexpensive continuous light sources on Optical Coherence Tomography. Incandescent lamp and sunlight were applied to develop an imaging system with 2 μm of resolution (2 times better than ones commercially available). Therefore it was designed and built a sunlight collector with a tracking module included and a spectral domain optical coherence tomography imaging system. It was verified that low fluctuations of the solar spectrum intensity allow the use of this natural source on imaging systems.
