Abstract
VTT Technical research centre of Finland has developed a
MEMS Fabry-Perot interferometer (FPI) for the wavelength
range from 7.5 ?m to 9.5 ?m. The device consists of two
Distributed Bragg Reflectors (DBR) manufactured with MEMS
processing techniques. The full width half maximum of the
transmission peak is 150nm. This transmission peak can be
tuned from 7.5 ?m to 9.5 ?m by applying a control voltage
from 0 V to 30 V. A laboratory demonstrator has been put
together to show the use of this module as a part of a
spectral measurement setup. Several gas samples have been
measured with the setup and compared against measurement
results found in literature
