Laser active imager are introducing a new paradigm in the domain of surveillance. Because they provide the capacity to
image objects based on their reflectivity and not their emissivity, and because they provide a capacity to see through
glass. Moreover, because that being based on high-performance gated intensified tubes, they can operate in adverse
atmospheric conditions, and are becoming looked at as a very valuable tool to gather precise identification information at
long ranges. On the other hand, the laser source making this technology so interesting must offer a safe operational mode
of deployment.
In this paper, we will show the most recent results that this technology can achieve in ship identification and discuss how
to implement safety features to make the laser active imager an eye safe new tool for long range observation whatever its
wavelength.
This paper treats three aspects of construction and use of deformable mirror devices developed at National Optics Institute: technology, optics configuration (functional equations), and diffraction (Fourier analysis).
