Abstract:
1. A temperature sensor, comprising: a light conveyor that emits light; a light receiver disposed to receive light emitted from the light conveyor; a temperature sensitive element having at least one dimension that is temperature sensitive and that is disposed so as to physically and partially obstruct a path of a light beam between the light conveyor and the light receiver, wherein the temperature sensitive element variably modifies an intensity of the light received by the light receiver, wherein the intensity of the light is variably modified by a change in the at least one dimension of the temperature sensitive element, and wherein the change in the at least one dimension varies according to a temperature change of the temperature sensitive element; and an electronic device coupled to the light conveyor and the light receiver that includes a driver that controls an intensity of the light emitted from the light conveyor based on a feedback loop and using a reference signal, and wherein the electronic device includes at least one luminous intensity analyzer that analyzes the changes in intensity of the light received by the light receiver and outputs at least one signal.
