WebJun 12, 2024 · The ratio method works both ways: Pixel spacing center to center is 0.00389 and the image overlays 10 pixels then the image length is 0.00389 X 10 = 0.389mm. If imaged using a 500mm lens, the ratio of image to focal length is 0.389 ÷ 500 = 0.000078. The image was taken from aircraft flying at 22,000 feet. WebThe focal length of a lens is the measured distance from rear nodal of the lens array to the focused image when the object being imaged is at infinity. This lens-to-image distance elongates if the object is closer than infinity. While the focal length of the lens does not change, this elongated back focus is substituted for the focal length.
