Abstract
A fiber optic control device comprises a joystick having fixed thereon a pivot ball to enable the stick to have universal pivotal movement. The control has a base provided with a socket in which said pivot ball is held captive while permitting the joystick to have said universal movement. The invention provides a pair of swivel members, and pivotally mountings for said swivel members on the base for movement about non-coincidental axes. Slide driving connections are provided between said joystick and swivel members, for causing reversible movements of the members in response to universal movements of the joystick. Mirrors are carried by the swivel members, and a fiber optic light transmission device is provided, which is cooperable with said mirrors and which includes a source of light that is adapted to direct a light beam against the mirrors, thereby to provide output light signals which are a function of the virtual position of said joy stick at any time.
