Abstract
We report on the concept study of the IRIS On-Instrument WaveFront Sensors (OIWFS), a collaborative effort by NRC-HIA, Caltech, and TMT AO and Instrument teams. Our concept study includes work on the system design of the low order natural guide star wavefront sensors located on-instrument within IRIS as well as the NFIRAOS-IRIS interface. The OIWFS study involves patrol geometry, detector alternatives, sky coverage modeling, acquisition, guiding, and dithering scenarios, and interfaces with NFIRAOS, IRIS, and the TMT observatory. It also includes work on probe optics, mechanics, and controls, detector arrays and controllers, instrument rotator and cable wrap, and thermal and structural design of the OIWFS enclosure.
