Study of CMOS image sensors for laser beam position detection

We present a characterization study of commercial 2D image sensor in CMOS (complementary metal oxide semiconductor) technology to validate their use as reference laser beams position detection. We also study the performance of the sensors under high radiation environments. Finally an optical system composed by beam splitters and CMOS sensors has been designed, this unit permits a multipoint measurement that can be applied for monitoring straightness of large objects.
