Web11 Apr 2024 · 1.Introduction. Intense scattering occurs as the light propagates through biological tissues, smoke, ground glass, or other scattering media. In such cases, it is tough for the conventional optical camera to capture the image of the object due to the distortion of the light field [1].However, the information about the object is still in the distorted light … WebFor a thick lens a third term must be included to obtain the total refractive power, Here t is the lens thickness at the optical axis as illustrated in figure 1.9 . Equation ( 1.7 ) with Φ defined by equation ( 1.9 ) is known as Gullstrand's equation .
