Stabilizer, Image, Prism
Wednesday, September 20, 2006
An Image Stabilizer has been designed and developed containing a system to neutralize optomechanical instrument shakes (lenses, binoculars, and camcorders).
The Image Stabilizer system consists of a vari-angle Prism optical system and contains two transparent plates coupled by a flexible film. It is a sealed unit filled with a high-refractive-index fluid. Horizontal and vertical photodetector signals are fed to a microprocessor. The detected hand movement or other vibration inputs are sent from the microprocessor as input signals to tiny motors. The correcting signals provide the motors with instant and continuous adjustments to shape the Prism optical system.
There is also a non-prism Image Stabilizer, which uses tiny gyros controlled by a built-in microprocessor. This Image Stabilizer senses unwanted camera movement that triggers signals to a magnetic coil surrounding a special group of lens elements. The coil moves the lens group horizontally or vertically to counteract shake for maintaining a steady, centered image.
