摘要：

We are developing an instrument to study the morphology and kinematics of the molecular gas (H-2) and its inter-relationship with the ionized gas in star forming regions planctary nebulac and supernova remnants in our Galaxy and other galaxics, as well as the kinematics of the infrared emitting gas in starburst and interacting galaxics. This instrument consists of a water-free fused silica scanning Fabry-Perot interferometer (SFPI) optimized in the spectral range from 1.5 to 2.4 mu m with high spectral resolution (R=27000 at 1.5 mu m). It will be installed in the collimated beam of a nearly 2:1 focal reducer, designed for the Cassegrain focus of the 2.1 m telescopic of the San Pedro Martir National Astronomical Observatory, Mexico, in its f/7.5 configuration, yielding a field of view of 11.6 arc-min. It will provide direct images as well as interferograms to be focused on a 1024x1024 HAWAII array, covering a spectral range from 0.9 to 2.5 mu m.
