Abstract

In the present paper we discuss the method of image coding by multiple exposure of range-gated images. This method enlarges the depth mapping range of range-gated imaging systems exponentially with the number of utilized images. We developed a theoretical model to give a precise prediction of the number of permutations that can be used for image coding. For what we believe is the first time, we realized an image coding sequence for three range-gated images to enlarge the depth mapping range by a factor of 12. We demonstrate three-dimensional imaging in a range of 460 to 1000 m using a laser pulse width of 300 ns . Because of the impact of noise, a critical linking error occurs during the encoding of the intensity images. It is possible to reduce this error by the application of effective noise reduction strategies and the use of a threshold value to the tolerance drift of intensity levels.
