WORK CLASS & HIGH-SPEED ROV ADVANCED
IMAGING & LASER PROFILING SYSTEM
Compatible with large work class and high-speed ROVs or large AUVs, Pathfinder is a dual-swath system for use in missions where intervention is required at greater depths or when accelerated data collection is necessary
Pathfinder is a fully integrated, laser and imaging system with co-registered laser, stills and video. Consisting of two Scout stills and laser configurations on a large work class frame, alongside a single video camera, the system is designed to enable slower, large vehicles to collect dense dual data sets with millimetre precision. To offset the reduction in speed when compared with lighter observation class ROVs, this system gathers twice the density of data in each single transit. Featuring forward-looking synchronised video for when high-speed piloting is possible, Pathfinder can achieve double-swath data collection at speeds of up to 5 knots.

PULSAR I
The Pulsar I Strobe light is an Ultra High output LED-based Strobe light. The unique design of the strobe light means it can provide up to 150,000 lumen output power up to 10 millisecond pulse widths with low continuous power consumption from vehicle. The power bottle spreads out the instantaneous power delivered to the LEDs as a low power requirement from vehicle. This is achieved using a microprocessor controlled capacitor charge and discharge system within the power bottle. When used in conjunction with the Fast Fly Stills camera, these fast ultra-bright exposures allow users to extend imaging range and vehicle speed. It also extends the highest quality still imaging capabilities to smaller vehicles and AUVs.

VIDEO CAMERA & STROBE LIGHTING
- There are many limitations associated with traditional video cameras for AUV and ROV platforms. Motion and continuous lighting can create poor visibility due to scatter from particles and motion blur. Illumination range is generally compromised and high powered-lighting is necessary to achieve any adequate clarity.
- Using short exposure times for each frame, R300 overcomes these restraints. When combined with Cathx Ocean A8 strobe lighting, it delivers even greater benefits.
