OMS-Lite

(Product ID: OMS-4.0LT)

OMS-Lite is a simple, GUI-based pressure and temperature sensitive paint data processing software. The data reduction procedure for PSP involves taking the ratio of wind-off / wind-on images and converting this image to pressure using a calibration that relates this ratio to pressure. In practice, several other image processing steps are often required. These steps can include compensating for the background lighting, image alignment, image filtering, in-situ calibration and temperature correction, all of which are supported by OMS-Lite. The main window of OMS-Lite is shown below. It allows the user to load the relevant wind-off and wind-on data files, and to access any of the image processing and calibration features.​

The following images show a basic single-channel (single luminophore paint) data set being processed. The data set begins with the raw wind-on image. The background is then removed from the image, and then the image is filtered, then the wind-off/wind-on ratio is taken and converted to pressure.

OMS Professional

(Product ID: OMS-4.0P)

OMS Professional is a data processing software developed for higher-end users for experiments with multiple cameras and test conditions.  ProImage includes many image editing and data processing tools that the basic OMS-Lite does not, including ROI filters and bitmap resection to a 3D mesh.  A region of interest can be selected and cleaned up in OMS Professional to produce high-quality pressure or temperature fields.  Many additional features are available in OMS Professional to clean up images.  Imperfections such as screw holes, markers, and paint imperfections can be removed from the field.
