摘　　要：光在水中照明时,由于水介质和水中微粒的吸收和散射,光能量损耗很多,而且产生了严重的散射光,降低了成像质量。因此在水中,尤其是在浑水中进行水下观察时,必须解决散射光的问题。针对以上存在的问题,我们提出一种新的水下目标图像探测方法——非均匀光场水下目标图像探测方法,并在此基础上我们提出了一种理想的分布光场模式,即在水下三维空间坐标轴上按所在水介质光衰减规律分布的非均匀照明光场。该光场有效的降低了后向散射光的影响,能获得较远的水下探测距离。Light power in underwater target image detection attenuates sharply because of absorb and scattering, especially in turbid water. Backscattered light affects the image quality. Based on the shortage of classic illumination and laser illumination method, we innovatively puts forward Inhomogeneous Optic Field Theory, i.e. in the three dimension space coordinate, the optic field distribution follows the principle of light attenuation underwater. Recounts the basic principal of Underwater Image Detecting Method of Inhomogeneous Optic Field, theoretically solves the problem of back scattered light noise, and deducts the light distribution characteristic of the inhomogeneous optic field. This method can detect high-definition image underwater in panoramic depth.
