Patent ID: 8206030

Claim:
An optical temperature sensing system comprising: a plurality of means for both inputting light at a first optical wavelength band and outputting light at a second optical wavelength band; a plurality of means for absorbing said light at said first optical wavelength band and emitting said light at said second optical wavelength band; said light at said second optical wavelength band includes features dependent upon temperature of said absorbing means; a plurality of means for propagating said light at said first optical wavelength band from each one of said plurality of inputting and outputting means to a unique one of said plurality of absorbing means and propagating said light at said second optical wavelength band from each one of said plurality of absorbing means to a unique one of said plurality of inputting and outputting means; and means for positioning each one of said plurality of absorbing means in a fixed relative position with respect to one another wherein location of temperature reading for each of said absorbing means is determined based upon said temperature-dependent features and said fixed relative position of said absorbing means.
