APEX - Subsea Laser Image Scaling Projector
Available as :
APEX subsea laser module - Available for hire or purchase from Savante Subsea.
The APEX range of subsea laser scaling modules were designed specifically for marine habitat survey; supporting benthic environmental species research, stoney reef classification and oil and gas subsea decommissioning surveys. APEX projects an intuitive fixed size measurement scale onto the seabed. Four high-quality laser modules are arranged in a parallel configuration in a single housing and pass through the same sapphire viewport. Uniquely, the effects of refraction are the same for each laser beam passing into the water column. APEX lasers maintain parallel beams over a much longer range and provide greater accuracy than mounting multiple laser modules in a framework.
Underwater objects can be scaled and sized using an APEX laser in conjunction with any video or digital stills device without disturbing the subject. Advanced image processing software can also correct for digital stills photographs collected at highly oblique angles.
