Abstract: A simple optical design, keeping in view of the available components, has been worked out to develop the 'all sky imaging Fabry-Perot spectrometer' to study the spatial structures in thermospheric winds and temperature. This system comprises three subsystems, namely, (i) field widening front-end optics, (ii) high resolution Fabry-Perot spectrometer and (iii) a two-dimensional detector. The design details of the above imaging spectrometer that has been commissioned for routine observations from Mt. Abu along with the first results on 0I 6300 A airglow emission are presented and discussed.
