    Integrated optical coherence tomography and reflectometry system for ocular anterior segment imaging and tear film thickness evaluation

    We report an integrated optical coherence tomography (OCT) and reflectometry system for ophthalmology imaging. The dual-functional device provides a complementary high-resolution tear film evaluation by reflectometry and anterior segment imaging by OCT, offering a more comprehensive anterior segment examination. The imaging measurement capabilities have been demonstrated on a human eye as well as on a model eye. The minimum measured tear film thickness is 0.3 μ m with measurement resolution of less than ± 0.58 % of film thickness yet the OCT anterior segment offers a depth resolution of 7 μ m with a 45-nm bandwidth superluminescent light source at 840-nm center ...
