    1065nm and 1310nm MEMS tunable VCSEL light source technology for OCT imaging

    A novel vertical-cavity surface-emitting laser with a microelectromechanical tuning element enables high-speed, centimeter-range optical coherence tomography. Optical coherence tomography (OCT) is a noninvasive optical imaging technique that can generate micron-resolution 2D and 3D images of tissue and other scattering materials.1 First demonstrated for imaging the human eye and coronary arteries in 1991,1 OCT has become a clinical standard for diagnosing and monitoring treatment of eye disease, with approximately 16 million ophthalmic OCT procedures performed in the US in 2010.2 OCT can also be used for intravascular imaging of plaque to assess heart disease, cancer biopsy imaging, developmental ...
