Abstract
An optoelectronic synchro generator which comprises at least one photoelectric circuit element which includes a light source and an associated receiver. A rotatable shaft has mounted thereon, for rotation therewith, elements which define at least one optically effective surface spaced from the axis of rotation of the shaft and through which light coming from the light source impinges on the receiver when the surface is in a predetermined position during the rotation of the shaft. A removable cover covering the shaft and the photoelectric circuit element and a shield disposed between the receiver and the optically effective surface prevents the impingement of stray light on the receiver when the cover is removed.
Claims11
An optoelectronic synchro generator comprising at least one photoelectric circuit element, each including a light source and an associated receiver;
- a rotatable shaft;
- means mounted on the shaft both for normal rotation therewith and for selective adjusting rotation with respect thereto for defining at least one optically effective surface spaced from the axis of rotation of the shaft by which light coming from the light source impinges on the receiver when said surface is in a predetermined position during the rotation of said shaft;
- a removable cover which covers the shaft and the photoelectric circuit element;
- at least one shielding means disposed at least in front of the receiver, but behind the path of the means defining the optically effective surface when viewed from the receiver, for permitting light from the source to impinge on the receiver when the surface is in the predetermined position and for preventing the impingement of stray light on the receiver when the cover is removed.
