Early Work on OCT
While conducting research into sensing between 1986-1995, the Applied Optics Group (AOG) contributed towards several avenues which paved the way for the later development of what is known today as OCT. The AOG was involved in all three types of OCT; (i) Time domain (essentially a Michelson interferometer), (ii) Spectral or Fourier domain, where the interferometer output is sent to an optical spectrometer and (iii) Swept source, using a laser source is used which is swept within a band equivalent to that of the broadband source used in the time or Fourier domain OCT.
Key papers from this time include:
