Abstract
BIFROST is one of the upcoming visitor instruments within the ASGARD array. BIFROST will be deployed at the Very Large Telescope Interferometer (”VLTI”) and is currently under development at University of Exeter. We present the instrumentation design and implementation of a dual-field light source for the calibration and design of the BIFROST instrument within Exeter”Vanaheim”. The system consists of a beam expander and splitter with associated optics to create an on- and off-axis beam simultaneously. An approach to calibrate the angle of the off-axis beam using an open loop controller is discussed. This report will discuss the OpticStudioZemax design and the initial implementation of the system at Exeter.
