Adaptive TIL System for Long Range Laser Beam Projection with Enhanced Resolution
Agency / Branch:
DOD / ARMY
Efficient laser beam delivery on a distant target remains a key problem for practical implementation of tactical laser systems. Since the conventional target-in-the-loop (TIL) concept is generally not effective in such operational environments, new solutions are needed. MetroLaser has developed an innovative approach for effective compensation of laser beam aberrations in TIL systems. It is based on a recently devised technique that combines optical phase conjugation (OPC) with a TIL system for effective hot-spot formation. MetroLaser proposes to develop a method that should enable delivery of enhanced density laser energy to a target within a finite number of iteration cycles. Using the model based on an analogy between the TIL system and laser resonator, laser beam position on the target is performed at the image plane, resulting in reduced hot-spot formation time. During Phase I, we will study the method's operational performance and efficiency in combination with MetroLaser's proprietary instantaneous wavefront sensor. The results will help determine the optimal parameters for hot-spot formation on a scattering surface target for a laser beam propagating through a turbulent atmosphere. This will reduce program risk and lead to a robust brassboard system design that will be built, tested, and validated in Phase II.
