摘要

En 中文

单次拍摄的高光谱波前传感对于高功率激光中的空间-光谱耦合计量或快速材料色散成像等应用至关重要。在宽带照明条件下，传统波前传感器假设无色散波前，这使其不再适用。我们介绍了一种基于哈特曼波前传感原理的高光谱波前传感方案，采用多芯光纤作为哈特曼掩模来克服这些限制。我们的系统利用多芯光纤的角向记忆效应和有限的谱相关宽度，将波前梯度编码为位移，并将光谱信息编码为不相关的散斑图案。该方法保留了传统波前传感器的简单性、紧凑性和单次拍摄能力，仅略微增加了计算复杂度。它还允许在空间分辨率和光谱分辨率之间进行可调的权衡。我们证明了其在Apollon多拍瓦激光设施中记录单脉冲获取的高光谱波前立方体以及执行多光谱显微成像以表征色散相位物体的有效性。作者介绍了一种基于多芯光纤的高分辨率和光谱分辨的光学波前传感器。该仪器通过单次拍摄捕获信息，推动了超快激光计量和定量色散显微术的发展。
