Measurements of pressure-sensitive paint (PSP) have been performed using new or\nnon-scientific imaging technology based on machine vision tools. Machine vision camera systems\nare typically used for automated inspection or process monitoring. Such devices offer the benefits\nof lower cost and reduced size compared with typically scientific-grade cameras; however, their\noptical qualities and suitability have yet to be determined. This research intends to show relevant\nimaging characteristics and also show the applicability of such imaging technology for PSP. Details of\ncamera performance are benchmarked and compared to standard scientific imaging equipment and\nsubsequent PSP tests are conducted using a static calibration chamber. The findings demonstrate\nthat machine vision technology can be used for PSP measurements, opening up the possibility of\nperforming measurements on-board small-scale model such as those used for wind tunnel testing or\nmeasurements in confined spaces with limited optical access.
