Hillel Price's recent manuscript - Development of next generation low-cost OCT towards improved point-of-care retinal imaging was the most downloaded article in the most volume of Biomedical Optics Express. Congrats Hillel!
Low-cost optical coherence tomography (OCT) has shown promise in increasing access to noninvasive retinal imaging at the point of care, especially in low-resource environments. A next-generation low-cost OCT system is presented which improves performance over previous versions by employing balanced detection, improved spectrometer falloff, and an increased A-line rate of 40 kHz. An algorithm is presented for image display that uses a histogram matching procedure to improve contrast-to-noise ratio (CNR).
