title = "A comprehensive underwater laser imaging model based on temporal and spatial broadening",
abstract = "The imaging of underwater objects which have been illuminated by natural or artificial light has been of long-standing interest to investigators working in oceanographic environments. Analysis of the propagation of imaging light through water is complicated by extreme attenuating and scattering properties of water, especially multiple scattering. A comprehensive computer model to simulate the formation of underwater images has been presented in this article. The model incorporates the temporal and spatial broadening properties of the propagation of light in water. A degraded image is approximated as a convolution of an initial image and point spread functions (PSFs). The spatial PSF plays a significant role in describing the spatial propagation of light and image blurring due to forward scattering. The temporal PSF can describe the pulse broadening effect, which is of great significance to evaluate the performance of range-gated technology. Computed and measured images compare favorably. It is concluded that the use of spatial and temporal broadening models are convenient and viable techniques for analytic computation of underwater images. 2009 SPIE.",
