Spectrally encoded endoscopy (SEE) enables miniature, small-diameter endoscopic probes for minimally invasive imaging; however, using the broadband spectrum to encode space makes color and spectral imaging nontrivial and challenging. By careful registration and analysis of image data acquired by a prototype of a forward-viewing dual channel spectrally encoded rigid probe, we demonstrate spectral and color imaging within a narrow cylindrical lumen. Spectral imaging of calibration cylindrical test targets and an ex-vivo blood vessel demonstrates high-resolution spatial-spectral imaging with short (10 μs/line) exposure times.
光谱编码内窥镜检查（SEE）能够实现用于微创成像的微型、小直径内窥镜探头；然而，利用宽带光谱对空间进行编码使得彩色和光谱成像变得复杂且具有挑战性。通过对前视双通道光谱编码刚性探头原型采集的图像数据进行仔细配准和分析，我们展示了在狭窄圆柱形管腔内的光谱和彩色成像。校准圆柱形测试目标和离体血管的光谱成像显示，在短（10微秒/线）曝光时间下可实现高分辨率空间光谱成像。
