“Conventional” underwater camera systems-an update

Despite the emerging developments of exotic laser-based visual imaging systems for underwater use, there is still a significant place for “conventional” camera and lighting systems. This paper seeks to review this fairly mature conventional technology, by examining the trends in the underlying technologies which determine its continuing place in oceanic science and engineering. Specific existing sensors are reviewed, together with sensor developments, in order to establish a useful end-user perspective on current sensor choices. Some prospects for future developments are also presented for consideration by those involved in more advanced programmes
