我们扩展了本系列的前两篇论文[Appl. Opt. 50，4998-5011（2011），Appl. Opt. 50，5012-5022（2011）]的工作，以设计用于线性波数色散的复合棱镜，特别是用于谱域光学相干层析成像（OCT）。这些色散棱镜设计被认为是第一个满足直视几何结构中高分辨率OCT系统的要求的，其中它们可以用于缩小系统尺寸，提高光通量，减少杂散光，并减少由波长和波数采样域之间的内插引起的误差。我们展示了棱镜设计，可用于热源或宽带超辐射发光二极管的波长为850，900，1300和1375纳米为中心。
We extend the work of the first two papers in this series [Appl. Opt. 50, 4998–5011 (2011), Appl. Opt. 50, 5012–5022 (2011)] to design compound prisms for linear-in-wavenumber dispersion, especially for application in spectral domain optical coherence tomography (OCT). These dispersive prism designs are believed to be the first to meet the requirements of high resolution OCT systems in direct-view geometry, where they can be used to shrink system size, to improve light throughput, to reduce stray light, and to reduce errors resulting from interpolating between wavelength- and wavenumber-sampled domains. We show prism designs that can be used for thermal sources or for wideband superluminescent diodes centered around wavelengths 850, 900, 1300, and 1375 nm.
