In this work an enhanced wide range dual band spectral domain optical coherence tomography technique (SD-OCT) is presented to increase the depth and accuracy of the measurement of optical A-scan biometry. The setup uses a Michelson interferometer with two wide-spectrum Superluminescent Diodes (SLD). The emissions of the SLDs are filtered by a long-pass filter (900 nm) in front of the reference mirror. The light is spectrally decomposed using a single reflective diffraction grating (1,800 lines/mm) and the whole spectrum captured with two CCD line sensors. The capabilities of the system have been validated using a self-made human model eye.
在这项工作中，提出了一种增强的宽范围光谱域光学相干层析成像技术 (SD-OCT)，以提高光学 A 扫描生物测量的深度和准确性。该系统采用迈克尔逊干涉仪和两个宽谱超辐射发光二极管 (SLD)。SLD 的发射光在参考镜前通过长通滤波器 (900nm) 进行滤波。光通过单个反射式衍射光栅 (1800 线/mm) 进行光谱分解，并使用两个 CCD 线传感器捕捉整个光谱。该系统的性能已通过自制的人眼模型进行了验证。
