Abstract
Improved optical coherence tomography systems and methods to measure thickness of the retina are presented. The systems may be compact, handheld, provide in-home monitoring, allow the patient to measure himself or herself, and be robust enough to be dropped while still measuring the retina reliably.
Claims23
A compact optical coherence tomography (OCT) system to measure a thickness of a retina, the compact OCT system comprising:
- a detector;
- a light source configured to generate a light beam comprising a plurality of wavelengths;
- a plurality of optical elements coupled to the light source to direct the beam into the eye and generate an interference signal at the detector;
- and
- circuitry coupled to the detector and the light source to determine the retinal thickness in response to the signal,
- wherein the compact OCT system measures a change in retinal thickness at a precision less than an axial resolution of the compact OCT system, the change in retinal thickness comprising a first thickness at a first time and a second thickness at a second time,
- wherein the light source comprises a vertical cavity surface emitting laser (VCSEL) configured to vary an emission wavelength of the light beam over a range from about 5 to 10 nm.
