A translucent object hidden in a highly scattering medium is shown to be visible when the early portion of the transmitted diffuse pulse (snake photons) is detected. The use of the snake scattered photons to image objects depends on the scattering characteristics along a quasi-straight-line path that the photons traverse across the medium. A translucent object with different scattering characteristics compared with its surrounding medium will change the intensity of the snake photons. By scanning the medium across the laser beam and detecting only the snake photons, a translucent object hidden in a highly scattering medium could be located.
当检测到透射漫射脉冲的早期部分（蛇形光子）时，隐藏在高散射介质中的半透明物体就会显现出来。利用蛇形散射光子对物体成像取决于光子穿过介质时沿准直线路径的散射特性。与周围介质相比具有不同散射特性的半透明物体将改变蛇形光子的强度。通过在激光束上扫描介质并仅检测蛇形光子，可以定位隐藏在高散射介质中的半透明物体。
