PHaSR

AFRL/DELS PHaSR “Personnel Halting and Stimulated Response” program
 
This program was initiated as a man portable packaging concept where-in the team demonstrated a viable packaging concept for a low power visible laser, PHaSR1.  This was followed by a full-up design and development of PHaSR2 that incorporated two lasers, a visible laser and a medium power MIR laser.  As the electrical team lead, Mr. Allison was responsible for the conceptual system’s electronics design where in he defined the system level architecture and determined optimum partitioning for the various electrical/electronics subsystems identified.  He worked with the mechanical engineer in determining mechanical form factors and thermal management needs.  He led the electrical/electronics design team in designing and developing the embedded control system that was built around a single MPU.  Mr. Allison worked with the software engineer as he developed the system’s embedded code.  He accomplished the detailed electronics design and printed circuit board layouts for the various modules used in the system.  He supervised the technicians in the assembly of the 1st and 2nd product articles that have successfully completed all acceptance testing and has been evaluated by several of the funding organizations with the 2nd unit being delivered to the DOJ.  The success of PHaSR2 has lead to a follow on program, PHaSR-RIDLPersonnel Halting and Stimulated Response – Range Independent Dazzel Laser” (also known as the 3X program), it will utilize a higher powered MIR laser and add a laser range finder subsystem that will allow operation with variable range without exceeding allowed MPE.  Mr. Allison has over seen the preliminary design efforts for this program.
