Paper Abstract

This paper presents some aspects of the calibration plan that has been developed for NFIRAOS, the TMT first light MCAO system. The plan consolidates the best practices from current 8-meter class AO instruments, while also addressing the specificities of NFIRAOS. We present the calibration hardware that will be available in NFIRAOS, including artificial sources, diagnostic detectors and supporting software. We then discuss two key calibration procedures in more details: the measurement of the DM-WFS interaction matrix and the multi-conjugate AO correction of the NFIRAOS non-common path aberration.
