6.1 Optics
6.1.1 System Optics
The Vibrometer was used with the GOS lamp November 21st collecting several types of jitter data at the ViSP slit plane focus. Many narrow, repeatable frequencies are present in the data. Impulse response of various mirrors is a work in progress, with several examples showing very clear and repeatable frequency “fingerprints”. This will be useful in upcoming vibration mitigation efforts.
Image jitter of the DKIST beam path from the GOS lamp to the ViSP slit plane recorded over 10 minutes with minimal activity and most systems parked / off. Many narrow and repeatable frequencies are present in the DKIST beam:
