| 摘要 |
<p>The present invention comprises devices and methods that deliver electromagnetic radiation (EMR) from an emitter to a target and employ laser or sonar (a sensing method) to measure distance between target and the EMR emitter and automatically signal the emitter control circuitry to vary either the position or the power output of the emitter (as appropriate) in order to ensure that the effect of any change in distance on the energy incident to the target is compensated rapidly and automatically. In a preferred embodiment, the device is a hand-held, non-contact heatbeam dolorimeter.</p> |
