Low Cost OCT

Optical coherence tomography

Optical coherence tomography (OCT) is a well-established medical imaging system that has become an essential retinal imaging tool for ophthalmologists. However, their cost of up to $150,000 for clinical systems has restricted access to only large eye centers. There is a significant opportunity for using OCT at the point of care if a low cost instrument were available. Here we seek to minimize the cost of the instrument by a few thousand dollars that provides comparable performance with the clinical system by using inexpensive components such as uncooled SLD for the light source and liquid lens for the scanner. We will demonstrate the capability of the low-cost OCT by imaging the animal retina. Figure modified from Song et. al. 2019.
