Abstract
A system and method for removing and reinstating a sight of a weapon without changing a boresight is disclosed. A reference optical device is installed on a rail of the weapon and then the sight is installed on the rail. An attitude determination unit determines a change in attitude of the sight with respect to the boresight. The aim point of the weapon in the sight is compensated accordingly based on the change in attitude without changing the boresight by utilizing a compensation module. This allows retaining the boresight even when the weapon sight is removed and reinstalled. Thus weapon sight can be mounted anywhere on a weapon without the need to boresight the weapon.
Claims17
A method for removing and reinstalling a sight of a weapon without changing a boresight comprising:
- installing a reference optical device on a rail of the weapon;
- installing the sight on the rail;
- determining a change in attitude of the sight with respect to the boresight;
- and
- compensating the aim point of the weapon in the sight based on the change in attitude without changing the boresight.
A method for automatic alignment of a sight of a weapon with a boresight without changing the boresight comprising:
- installing a reference optical device on a rail of the weapon;
- installing the sight on the rail;
- allowing a light to reflect from the reference optical device and from an optical device in the sight;
- obtaining a resultant light reflected from the reference optical device and from the optical device in the sight;
- processing the resultant light;
- determining a change in attitude of the sight relative the boresight;
- and
- automatically adjusting the sight based on the change in attitude, whereby alignment is insensitive over time to shifts due to shock, vibration and temperature so that differential measurement provides temperature and vibration hardening.
A system for removing and reinstalling a sight of a weapon without changing a boresight comprising:
- a reference optical device installed on a rail of the weapon;
- the sight installed on the rail;
- an attitude determination unit for determining a change in attitude of the sight with respect to the boresight;
- and
- a compensation module for compensating an aim point of the weapon in the sight based on the change in attitude without changing the boresight.
