Abstract

We describe an innovative optically computed optical coherence tomography (OC-OCT) technology. The OC-OCT system performs depth resolved imaging by computing the Fourier transform of the interferometric spectra optically. The OC-OCT system modulates the interferometric spectra with Fourier basis function projected to a spatial light modulator and detects the modulated signal without spectral discrimination. The novel, to the best of our knowledge, optical computation strategy enables volumetric OCT imaging without performing mechanical scanning and without the need for Fourier transform in a computer.

摘要

我们描述了一种创新的光学计算光学相干断层扫描（OC-OCT）技术。该 OC-OCT 系统通过光学计算干涉光谱的傅里叶变换来实现深度分辨成像。OC-OCT 系统用投影到空间光调制器的傅里叶基函数调制干涉光谱，并在不进行光谱分辨的情况下检测调制信号。据我们所知，这种新颖的光学计算策略使 OCT 体积成像成为可能，无需进行机械扫描，也无需在计算机中进行傅里叶变换。
