OCT Technologies, Applications Showing Great Promise


A panel of industry experts weighs in on recent and future advances in optical coherence tomography, and offers a look at the market.. OCT is growing. As we reported in the July issue, the optical imaging market is set to reach $1.9 billion by the end of 2018 – a compound annual growth rate of 11.37 percent – and OCT makes up 70 percent or more of that market, according to a study by Research and Markets.

But if you only go by the numbers, you don’t get the whole story. Sure, 70 percent is great for OCT, but where is it really going? To get a more in-depth perspective, BioPhotonics interviewed representatives from companies that are big players in the OCT sphere: Jon Holmes, CEO of Michelson Diagnostics in Orpington, Kent, England; Douglas Malchow, manager of business development for the industrial sector at UTC Aerospace Systems (Sensors Unlimited Products) in Princeton, N.J.; and Dr. Kester Nahen, managing director of Heidelberg Engineering in Germany.The retinal image was captured using UTC’s high-resolution InGaAs cameras for SD-OCT.

Michelson Diagnostics produces the VivoSight multibeam OCT scanner, which is used for dermatological applications, and makes high-resolution InGaAs cameras for spectral domain OCT and full-field OCT in the 1- to 1.6-µm- wavelength range. The cameras provide line-to-line phase stability for general, polarization-sensitive or Doppler imaging. Heidelberg Engineering specializes in diagnostic devices for ophthalmology applications, including the Spectralis product platform, which includes a spectral-domain OCT system with active eye tracking.
