Abstract
An electrodynamic optical scanner and stabilizer for a pointer and tracker used on a seeking device. The seeking device used for air to air missiles, air to ground missiles, or any other use of a scanner requiring scanning speed and accuracy with the ability to generate different scanning patterns.
Claims3
An electrodynamic optical scanner and stabilizer for a pointer and tracker used on a seeking device, the scanner and stabilizer comprising:
- a mounting plate;
- a first electrodynamic driver attached to the mounting plate;
- a second electrodynamic driver attached to the mounting plate;
- control system means connected to the first and second electrodynamic drivers for driving the drivers through drive leads connected to the drivers and receiving position feedback of the drivers through position leads connected to the drivers;
- a flexible pivot attached to the mounting plate;
- flexible mounts attached to the drivers;
- and
- a reflector attached to the flexible pivot and the flexible mounts of the drivers, the drivers disposed in various predetermined positions adjacent the reflector for moving the reflector on the flexible pivot in a desired scanning pattern, such as conical, rosette and raster among others.

An electrodynamic optical scanner and stabilizer for a pointer and tracker used on a seeking device, the scanner and stabilizer comprising:
- a mounting plate;
- a first electrodynamic driver attached to the mounting plate;
- a second electrodynamic driver attached to the mounting plate, the drivers including a ferromagnetic housing having a drive coil and a position coil mounted therein, the drive coil disposed around the position coil with a permanent magnet mounted inside the position coil, when the driver is energized, the drive coil moving linearly in relationship to the position coil, the drive coil connected to a connecting plate;
- control system means connected to the first and second electrodynamic drivers for driving the drivers through drive leads connected to the drivers and receiving position feedback of the drivers through position leads connected to the drivers, the control system means having drive electronics connected to the drive leads and a feedback processor connected to the drive electronics and the position leads, the drive electronics controlled by signals from a position controller, the position controller connected to a pattern generator for receiving a desired scanning pattern command signal;
- a flexible pivot attached to the mounting plate;
- flexible mounts attached to the connecting plates of the drivers;
- and
- a reflector attached to the flexible pivot and the flexible mounts of the drivers, the drivers disposed in various predetermined positions adjacent the reflector for moving the reflector on the flexible pivot in a desired scanning pattern such as conical, rosette and raster among others.
