利用超结构光栅分布布拉格反射镜（SSG-DBR）激光器，研制了基于光频域反射（OFDR）的光学相干层析成像（OCT）系统，该系统可实现波长在1533 ~ 1574 nm范围内的分步调谐，调谐速度为10 μ s/0.1 nm。给出了离散扫频OFDR-OCT成像的理论表达式。OFDR-OCT图像显示了一些生物组织;提取的犬、人皮肤、人指甲和摘除的猪眼前段。
Optical coherence tomography (OCT) system based on optical frequency-domain reflectometry (OFDR) has been developed using a superstructure-grating distributed Bragg reflector (SSG-DBR) laser, which can tune the wavelength from 1533 to 1574 nm stepwise with tuning speed of 10micro s per 0.1 nm step. Theoretical expressions of OCT imaging by the discretely swept OFDR-OCT system are described. OFDR-OCT images are demonstrated for a few biological tissues; an extracted canine, human skin, human nail, and anterior segment of enucleated porcine eye.
