Remanent Imaging, a novel concept for imaging aquatic organisms
KAUST Research Conference on Robotics and Autonomy 2023
Speaker: Pierre R. Martineau, founder and CEO, Martineau & Associates, Inc.
Abstract:
I will present Remanent Imaging ("RI"), an innovative method to record the movement of aquatic organisms, both transparent and opaque. It is currently used to monitor and analyze the behavior of zebrafish—a ubiquitous animal model in medical research—which are transparent in the larval stage.
Standard video captures sequences of sharp, briefly exposed snapshots free of motion blur, at a frame rate that directly constrains time resolution. By contrast, RI records sequences of long exposure images back-to-back to capture motion blur continuously from frame-to-frame. Movement trajectories can be directly extracted from the morphology of individual or stacked sequences of images, at a time resolution that depends on movement amplitude and sensor pixel resolution.
I will show actual zebrafish darkfield illuminated RI sequences as well as how the technique can record aquatic organisms ranging in size from 0.1 to 50 mm and yield orders of magnitude improvements in computational performance and data efficiency.
I will also discuss how to create darkfield conditions and how to apply RI to process control.
