Abstract
The laser illumination techniques described permit spatial discrimination. That is, they allow the isolation and viewing of small volumes of space, while ignoring the scattering or the light which orginates elsewhere in the line of sight. These techniques allow an improvement in signal to noise illumination ratio in a wide variety of applications. The Atomic Wea-pons Research Establishment's original interest in this field was to enhance the discrimination against the self light of luminous shocks front beyond that given by narrow band illumination and viewing. However there are many diverse applications of spatial discrimination and there are other ways of obtaining spatial isolation. Some of these concepts are illustrated here by reference to the problem of seeing underwater where their help could bring economic benefits.
