Large space optical systems will require on-orbit wavefront sensing and control systems to correct misalignments and figure errors incurred during manufacture, launch and deployment.
In this paper, we present the experimental validation of a focus-diverse wavefront sensing algorithm with comparative interferometric measurments of a perturbed test mirror.
This paper describes the engineering version of the STCS, the algorithms it incorporates, and methods of communicating with the testbed hardware.
The NGST Phase Retrieval Camera (PRC) is a portable wavefront sensor useful for optical testing in high-vibration environments. Primary applications of the PRC are testing and experimenting with NGST technology demonstrator mirrors, along with exploring other wavefront sensing and control problems not easily studied using WCT. An overview of the hardware and testing results will be presented.
This presentation will detail the packaging and hardware chosen for the PRC, the PRC software, and calibration of the instrument.
This paper presents the results of our experiments and simulations on the NGST Wavefront Control Testbed (WCT) to demonstrate PCF Monitoring and in-focus wavefront control.
