The overall experimental setup is divided into the AtmoHIT module and the Ground Segment. The experiment design includes: mechanical design, electronical design, optical design, thermal design and so on.
-Mechanical design
The mechanical design of the AtmoHIT experiment can be divided into the spectrometer instrument and the VIS camera instrument.
-Electronical design
The electronic concept for the AtmoHIT experiment consist of a total of four printed circuit boards (PCB) for different tasks: the Power-Supply-Unit (PSU); the VisCAM-Board; the Front End-Electronic board (FEE) and the Proximity-Electronic (PXE).
-Optical design
The optical mainly consists of two parts. The fore-optics is the first optical part of the complete spectroscopic system and is the biggest optical component of the setup. A Spatial Heterodyne Spectrometer (SHS) is used to measure the intensities of the oxygen emission lines.
-Thermal design
In general, the AtmoHIT experiment is relatively insensitive to temperature changes. Considerable effort was undertaken to temperature stabilize the SHS, which is analysed in the thermal design.
