Current Issues and Next Steps

As described above one of the main issues is regarding the WOT plate scale. Although it does not affect the quality of the data, it is required for the data synthesis process. This problem has been addressed and new data includes information about this para- 

The AIM lab where WIIT is housed is a temperature controlled laboratory. However, during measurements corresponding to the data presented here the temperature control system was turned off to avoid air turbulence. Currently an enclosure has been positioned around WIIT to be able to operate the system with cooled temperatures. This allows to reduce issues like drifts in the baseline source separations, which does not affect the visibility analysis but is very important for the data synthesis. 

In this chapter the two Spectro-Spatial Interferometry Testbeds in which I have been involved during my programme have been presented the FIRI laboratory testbed and WIIT, the Wide-field Imaging Interferometry Testbed. Both testbeds demonstrate the theory of Double Fourier Spatio-Spectral Interferometry or the application of a Fourier-transform spectrometer (FTS) to aperture synthesis interferometry presented in the previous chapter, at far infrared wavelengths and optical wavelengths, respectively. 

The knowledge acquired by working with these systems has been applied in the development of the instrument simulator FllnS described in the next chapter, as well as for its validation. In Chap. 5 a more detailed validation of FllnS via the FIRI testbed is presented.
