In a FLIR/laser based targeting and imaging system the ability to recognize, detect, locate and/or track targets in an area of interest is significantly improved by reducing the fixed and dynamic alignment errors between the IR LOS and the laser LOS. Fixed alignment errors between the IR LOS and the laser LOS. Fixed alignment errors are reduced with an improved internal boresight module (Fig. 10) and corresponding boresight method. Dynamic alignment errors are reduced with an opto-electric subsystem that employs a single pitch (405) bearing and a common pitch/yaw afocal (401) for both the laser energy and the IR energy. A segmented window (Fig. 17) in the system housing includes a …

Why it's free to use
- Filed April 1, 1997 and granted March 12, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 1, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 1, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
