About the Cardiff-UCL FIRI Testbed

The Cardiff-UCL FIRI testbed can undergo improvements in the modelling of the testbed itself as well as hardware upgrades. 

The use of a step and sample scan method is inefficient compared with rapid scan techniques for the spectral drive. At the time of writing, this change has already been performed. More specifically, fhe fast scan drives have been upgraded to a higher specification to allow finer monitoring of the position. 

To study more complex scenes with the FIRI testbed there exist two possibilities first, to develop tunable sources which can be calibrated with standard FTS instruments, and second, following the concept of the apertures in front of the Mercury Arc Lamp, to photolithographically build a complex scene. To recreate the sampling of the MV-map, this complex scene can be rotated as the scenes generated by CHIP for WIIT.
