We demonstrate the optical imaging of objects through highly scattering media using a subtractive optical Kerr gate (SOKG). The SOKG extracts ballistic light via a subtraction operation involving a speckle-suppressed image using supercontinuum illumination and a background image captured with the ballistic light temporally excluded. By using this method, the contrast is significantly enhanced, while the sharpness and spatial resolution of the image are also significantly improved relative to traditional optical Kerr gate imaging. This imaging approach shows immense potential for applications involving the observation of the high-speed breakup of liquid cores in strongly scattering fuel sprays.

我们展示了通过减色光学克尔门（SOKG）通过高度散射介质对物体进行的光学成像。SOKG通过涉及超散光照明的散斑抑制图像和在时间上被排除的弹道光捕获的背景图像的减法运算来提取弹道光。通过使用此方法，相对于传统的光学克尔门成像，对比度得到了显着增强，而图像的清晰度和空间分辨率也得到了显着提高。这种成像方法显示出巨大的潜力，可用于涉及在强散射燃料喷雾中观察液芯高速破裂的应用。
