Abstract
Systems and methods for determining a position of an object are provided by the present invention. Light is captured by at least one collector. Each collector has a first opening through which light enters that is larger than a second opening through which light exits. The exiting light is used by at least one light detector to generate signals. The position of the object is determined based upon the generated signals.
Claims21
An optical position device for determining a position of an object, comprising:
- a plurality of collectors configured to each capture light, each of the plurality of collectors having a first opening through which light enters and a second opening, having a size smaller than a size of the first opening, through which light exits;
- a plurality of light detectors, each associated with a respective one of the plurality of collectors and configured to detect the exiting light and generate a signal responsive to the exiting light;
- and
- processing electronics configured to determine a position of the object based upon the generated signals.
