Analysis of the alignment of a schlieren system for tele-operation

The schlleren observation technic[ue can be used in microgravity experiments. Alignment features for the gratings of a multiple source sharp focusing schlieren system have been analysed. Measurements have been performed to verify the theoretical predictions which show good agreement with the analysis results. The analysis allows for the...

Feasibility assessment of the in-flight alignment of a Schlieren system using tele-operation and automation

At NLR a multiple source schlieren observation system has been developed as part of the Tele-operated Prototype Optical Diagnostic Instrument (TelePODI). A technique for the tele-operated alignment of the gratings of the schlieren system is described. Future requirements for teleoperation/automation motivated a detailed analysis as a case study....
