An advanced Fabry-Perot interferometer with an innovative focal plane detection technique called the Circle-to-Line Interferometer Optical (CLIO) system and high quantum efficiency CCD has been developed and field tested. During the field test at Ann Arbor, Michigan, 9 interference orders were collected simultaneously for the OH(7,3) P{sub 1}(3). A signal-to-noise ratio (SNR) of 10-100 was achieved with 1-minute integration. Compared with conventional FPI, the CLIO-FPI is more sensitive and capable of collecting airglow data at much higher temporal resolution. The first operational CLIO-FPI will be deployed at the Polar Cap Observatory (PCO) at Resolute, Northwest Territories, Canada (74{degree}54{prime}N, 94{degree}54{prime}W), in 1994. This new instrument is expected to enhance the ability to study the Earth`s mesosphere and lower thermosphere.
