DESIGN HISTORY AND THEORY OF OPERATION OF A TWO-CHANNEL, ROCKET-BORNE EBERT GRATING SPECTROMETER
Abstract:
A two-channel Ebert grating spectrometer is described. The ultraviolet channel scans the 2300 A to 7000 A spectral region. The infrared channel scans the 2.3-mu to 7-mu spectral region. Built-in calibration is provided to monitor the response of the two spectral channels and the operation of the telemetering system. Data commutation is used to time-multiplex the information onto a single-channel data link. The system is fully transistorized and both mechanical and electrical design are compatible with rocket borne environments. In addition to the design and development history and general design considerations for this type of instrument, information is also presented on the details of operation of the instrument.
