In this paper we present and test a Digital Image Correlation (DIC)-based single camera pseudo-stereo system that uses a biprism in front of the camera objective to split the scene in to two equivalent lateral stereo views in the two halves of the sensor. Such optical arrangement simplifies image pairs matching and, more importantly,makes possible a compact set-psuitable forminiaturization. To correct the image distortion caused by the refraction through the biprism, a proper optimization-based procedure is sed to map the 3D reconstruction error function over the entire measurement volume.The inverse of the volumetric distortion function is the napplied tothedouble-imageofasphericalsampleplaced in narbitrary position to evaluate the shapere construction accuracy.Finally,thecapabilityofthe proposedsystemtoaccuratelytrackdeformationinreal-timeistestedviaaninflationtestonacircular latex membrane.
