Statistical approach to systems engineering for the Thirty Meter Telescope
Systems engineering Thirty Meter Telescope performance estimate
2015/5/13
Core components of systems engineering are the proper understanding of the top level system requirements, their
allocation to the subsystems, and then the verification of the system built against th...
Investigation of Thirty Meter Telescope Wavefront Maintenance Using Low Order Shack-Hartmann Wavefront Sensors to Correct for Thermally Induced Misalignments
Wavefront Sensing and Control Active Optics On-Instrument Wavefront Sensor
2015/5/13
We evaluate how well the performance of the Thirty Meter Telescope (TMT) can be maintained against thermally
induced errors during a night of observation. We first demonstrate that using look-u...
Normalized Point Source Sensitivity for Off-Axis Optical Performance Evaluation of the Thirty Meter Telescope
Point Source Sensitivity Optical Performance Metric Optical Modeling
2015/5/13
The Normalized Point Source Sensitivity (PSSN) has previously been defined and analyzed as an On-Axis
seeing-limited telescope performance metric. In this paper, we expand the scope of the PSSN...
