Abstract
Spectrally overlapping long period gratings (LPGs) are demultiplexed
for the first time using a Moiré 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.
