Abstract
An apparatus (10) for measuring temperature using luminescence thermometry, comprising: a photon emitter (42) for providing photons (3) of at least a first frequency; photoluminescent material (30) that produces photons (5) of at least a second frequency in response to the incidence of photons (3) of the first frequency; one or more photon receivers (44); and an optically dispersive element (50) for directing photons (5) of at least a second frequency produced by the photoluminescent material (30) into the photon receiver(s).
Claims26
An apparatus for measuring using luminescence, comprising:
- a photon emitter for providing photons of at least a first frequency;
- one or more photon receivers for receiving photons of at least a second frequency;
- characterized in that the apparatus further comprises
- an optically dispersive element for directing photons of at least the second frequency into the one or more photon receivers.
A luminescence measuring apparatus, comprising:
- a radiation source;
- photoluminescent material that produces photons of at least one frequency in response to the incidence of radiation from the radiation source;
- and characterised in that it further comprises:
- a plurality of photon receivers;
- and
- a control mechanism for controlling which of the plurality of photon receivers are enabled.
A luminescence measuring apparatus, comprising:
- a radiation source;
- an object adapted to move in a first direction and having photoluminescent material thereon, that produces photons of at least a second frequency in response to the incidence of radiation from the radiation source;
- and characterized in that it further comprises:
- a plurality of photon receivers distributed along the first direction.
A method of measuring luminescence, comprising the steps:
- providing photons of at least a first frequency from a photon emitter;
- directing the photons of at least a first frequency at a photoluminescent material thereby producing photons of at least a second frequency;
- directing the photons of the at least a second frequency through an optically dispersive element;
- wherein the optically dispersive element directs the photons of the at least a second frequency to at least one photon receiver.
