A technical discussion of the challenges and solutions for High Definition (HD) video systems in subsea applications contrasted against traditional analog technology.

Diode lasers are particularly well suited to marine applications because of their insensitivity to vibration, long life, compact size, wide input voltage, and instant restrike.

While great attention is given to LED solid state devices during their rapid evolution, they are just one component in a larger electronic circuit.

Two of the most important performance parameters for underwater lights are beam control and beam angle, both of which are primarily functions of reflector design rather than lamp type.

Following ideal reflector design, the placement of an underwater light, or "luminaire", relative to the camera will have the greatest affect on image quality, due to "Common Volume Scattering," which can result in backscatter in the present of suspended particles or organisms.
