Early-arriving photons of 100-fs laser pulses transmitted through highly scattering media have been detected by a streak camera. Because of their partial spatial coherence, they are affected by diffraction from small hidden discontinuities. The experimental data of the patterns are analyzed with Fresnel diffraction theory and then corrected accordingly. Submillimeter hidden objects were scanned and imaged. Diffraction correction resulted in a significantly improved contrast in the hidden object's image.
条纹相机已检测到通过高散射介质传输的100飞秒激光脉冲的早到光子。由于它们的部分空间相干性，它们会受到来自小的隐藏不连续处的衍射影响。用菲涅耳衍射理论分析图案的实验数据，并据此进行校正。对亚毫米级隐藏物体进行了扫描和成像。衍射校正显著提高了隐藏物体图像的对比度。
