FIGURE 1. On-line automated optical inspection & process-control system. 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 process control signals & 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.
