Optical tool with dynamic electromagnetic radiation and a system and method for determining the position and/or motion of an optical tool
First Claim
1. A system comprising:
- a tool configured to emit electromagnetic radiation, wherein one or more aspects of the emission of electromagnetic radiation by the tool varies as a function of time;
a detection arrangement configured to receive electromagnetic radiation emitted by the tool and to generate one or more output signals based on one or more properties of the received electromagnetic radiation; and
a processor configured to receive the one or more output signals generated by the detection arrangement and to determine the position of the tool with respect to the detection arrangement based at least in part on the received one or more output signals.

Abstract
A tool configured to emit electromagnetic radiation therefrom such that one or more aspects of the emission of the electromagnetic radiation may be varied as a function of time. By varying the emission of the electromagnetic radiation as a function of time, the tool may enable information related to its position and/or motion to be determined with an enhanced specificity based on detection of the emitted electromagnetic radiation. For example, the varying emission of the electromagnetic radiation may enable a three dimensional position of the tool to be determined, may enable the position of the tool to be determined in three rotational degrees of freedom, and/or may enable time derivatives of these (and other) position information to be determined to quantify motion of the tool. In some implementations, the emission of the electromagnetic radiation may be varied such that position and/or motion information related to a plurality of tools may be determined simultaneously (or substantially simultaneously).
