Abstract
Spectrally overlapping long period gratings (LPGs) are demultiplexed for the first time using a Moire grating structure so as to encode spectral differences between all of the gratings. Results of performing thermal tests showed that the system noise was 1.2 K and the crosstalk between two sensors was below a correlation level of 0.1 K.
