Experimental equipment for the measurement of thermofluidynamic conditions in fluid physic experiments on board of space platforms

Computerized devices are described which have been designed, realized and ground tested for the non-invasive measurements of surface temperature, of interface geometry and of liquid velocity. This equipment has been used in laboratory researches on liquid floating zones which simulate space experiments in fluid physics. The systems may be used for space experiments, once TV and thermographic recordings are available on ground after the mission. Other solutions are suggested which would imply an on-board microcomputer system for data preelaboration and which would substantially reduce the amount of data to be recorded and/or transmitted to ground.
