Axelrod Associates develops and delivers integrated systems with optics, electro optics sensing, electronics & computer-control (signal processing, output control signals, displays, etc.)
OBUST SYSTEMSM methodology is used to automatically compensate for acceptable changes in product features and system performance during operation. It monitors, modifies & upgrades performance. It bullet-proofs the system.


FIGURE 1. On-line automated electro optics system for quality & process control. Determines ovality & concentricity, detects defects, assesses accept/reject. Coated wire moves from right to left through five stations: pin-hole detection, O.D.(x, y), coating thickness gauging (+/- 0.00001"), optical defect detection, defect marker. Generates product control signals and quality reports. Wire used in critical implanted medical device. System won annual award of multi-billion dollar U.S. corporation.


FIGURE 2. Laser communication system.
Free-space, duplex operation. Input signals through fiber optic or coaxial cables of transmitter modules. Output signals through fiber optic or coaxial cables of detection modules.


FIGURE 3. Tracking & positioning of friction-welding head for new-generation automated fabrication of commercial jet-planes. Compact system combines laser, electronic camera, folding optics and computer.
