Abstract: Apparatus for detecting airfield light emitters, the apparatus including a plurality of light detection cameras, each detecting at least one respective waveband of electromagnetic radiation within the electromagnetic spectrum, each of the light detection cameras producing a plurality of respective spectral images, and a processor coupled with the light detection cameras, thereby generating a multispectral image of the airfield light emitters from the spectral images, the multispectral image including a multi-dimensional set of spectral values, wherein the processor further determines which combination the multi-dimensional set of spectral values corresponds with a plurality of distinct light emission characteristics of the airfield light emitters by identifying a particular spectral signature corresponding to the multi-dimensional set of spectral values, wherein the processor produces an enhanced image from those spectral values of the multi-dimensional set of spectral values which correspond to the determined combination.

Abstract: A medical Wide-Field-Of-View optical-tracking-system for determining the position and orientation of a target-object in a reference coordinate system. The system includes at least three light-emitters, at least one optical-detector and a processor. The processor is coupled with each optical-detector. One optical-detector is a Wide-Field-Of-View optical detector, which acquires an image of the light-emitters within the field-of-view thereof. Each Wide-Field-Of-View optical-detector includes an optical-sensor and two optical-receptors. The processor determines the position and orientation of the target-object in the reference coordinate system according to representations of the light-emitters. Each light-emitter is within the field-of-view of an optical-detector. Each optical-detector and each light-emitter is attached to one of the target-object and a reference-location. The target-object and the reference-location are respective elements in a tuple including two elements from a group consisting of a display, a patient-body-location, a-medical-tool, physician-body-location, and a fixed-position.
