An electronic rifle scope that automatically compensates for unsteady aim and recoil is being developed by US defence contractor Raytheon. Using the sight, snipers and police marksmen would no longer need to manually adjust their sight to account for the slight sideways movement that occurs when they pull the trigger.
The digital sight uses a high-resolution digital camera to…
zoom in on a test target and superimposes a cross-hair in the centre of the image. When the marksman aims and fires, an accelerometer detects the small shock pulse created as the pin strikes the cartridge cap and starts the camera snapping. It captures a rapid series of digital images, which record the motion caused by the gun’s recoil.
An image processor then compares the aim in the original picture with an image of the where the target was hit and electronically moves the cross-hair to compensate for any discrepancy. From then on, anything seen in the scope should, in theory, be a guaranteed bull’s eye.
