Abstract
The red laser diode serial LiDAR (Light Detection and Ranging) imager system we have developed combines the ad-vantages of traditional optical and acoustic solutions while overcoming their disadvantages when applied to fish surveys. Red laser illuminators can be configured to be eye-safe, unobtrusive, and allow for 24/7 operations. This new approach is an adaptation of an existing technology that is compact, cost-effective and can be easily mounted on or around different marine survey equipment. The equipment is designed for long-term, maintenance-free operations. It generates a sparse pri-mary dataset that only includes detected anomalies, thus allowing for efficient, real-time, automated, low bandwidth animal detection, classification and identification.
