Abstract

In pursuit of real time/on-the-fly image processing, a sensor with embedded algorithms for tracking is tested to determine its aliasing window whilst under laser interrogation. The characterization of the sensors and this interaction are explored, as well as the limitations thereof. This is follow on work to previous studies, in which both fixed frame rate sensors and adjustable frame rate sensors were tested to show the difference in response and functionality when subjected to Quantum Cascade Laser (QCL) modulation. A MIRAGE^[1] Infrared Scene Projector (IRSP) is used to add baseline signature for the sensor to follow before the laser signal is introduced. Discussions of further advancements in anti-aliasing algorithms are included as well.
