摘要
报道了一种适用于平衡探测型光学相干层析(OCT)成像系统的透射式快速扫描光学延迟线(RSOD)。该透射式RSOD主要由反射型闪耀光栅、傅里叶透镜、快速扫描振镜、直角棱镜和反射镜组成,具备了反射式RSOD同样的相位调制、轴向扫描、调节色散功能。实验表明,基于透射式RSOD构建的平衡探测型OCT系统,与基于反射式RSOD的非平衡探测型OCT系统相比,图像质量明显提高。
Abstract
This paper presents a transmissive rapid scanning optical delay line (RSOD) for balance detection based optical coherence tomography (OCT). This transmissive RSOD,consisting of a reflective blazed grating,a Fourier lens,a fast-scanning galvo-mirror,a right-angle prism and a mirror,possess functions of phase modulation,axial scanning and dispersion compensation in OCT just as a reflective RSOD. The developed transmissive RSOD is implemented in OCT for balance detection. Comparison study indicates that improved quality of imaging is archived by the transmissive RSOD based OCT,in contrast to that by a conventional reflective RSOD based OCT.
