我们使用参考照明的离轴几何结构演示了全视场扫频源 OCT。通过使用全息重聚焦技术，在大约 80 瑞利长度的测量深度上实现了均匀的横向分辨率。与标准轴上设置相比，伪影和自相关信号得到抑制，并且通过解决复共轭模糊度使测量深度加倍。正如之前在逆散射和全息术中所证明的那样，全息重聚焦是通过傅立叶域重采样有效完成的。它可以在超过 10 毫米的完整测量深度上以约 10 微米的分辨率重建完整的体积。离轴全场扫频 OCT 可实现高测量深度、跨越许多瑞利长度并减少伪影。
We demonstrate a full-field swept-source OCT using an off-axis geometry of the reference illumination. By using holographic refocusing techniques, a uniform lateral resolution is achieved over the measurement depth of approximately 80 Rayleigh lengths. Compared to a standard on-axis setup, artifacts and autocorrelation signals are suppressed and the measurement depth is doubled by resolving the complex conjugate ambiguity. Holographic refocusing was done efficiently by Fourier-domain resampling as demonstrated before in inverse scattering and holoscopy. It allowed to reconstruct a complete volume with about 10μm resolution over the complete measurement depth of more than 10mm. Off-axis full-field swept-source OCT enables high measurement depths, spanning many Rayleigh lengths with reduced artifacts.
