1. A dental curing instrument for curing a target, the target including a restorative material that is curable in response to application of light energy, the dental curing instrument comprising:

  • a light source capable of outputting the light energy to cure the restorative material, the light source being controllable to vary the light energy being output;

    a light sensor for sensing a light energy characteristic;

    an optical feedback path operable coupled to the light sensor, the optical feedback path being disposed to channel light reflected back from the target to the light sensor, wherein the light sensor is configured to sense the light energy characteristic with respect to the light reflected back from the target; and

    a controller operably coupled to the light sensor and the light source, the controller configured to vary, based on the light energy characteristic sensed by the light sensor, an operating characteristic of the light source from a first operating characteristic to a second operating characteristic to affect the light energy being output from the light source, wherein the light source is configured to output light based on operation at the first operating characteristic, wherein the light source is configured to output light based on operation at the second operating characteristic.
