SIAM – Secondary Image Angle Measuring Instrument

The Secondary Image Angle Measuring Instrument (SIAM) is a measuring device for the determination of angles between primary and secondary images for windshields. The included software allows the automatic determination of the angle as well as the recording of the angle together with its measuring position on the windshield.  The instrument uses a collimated laser as a source, and a telescope equipped with a log sensitivity camera as a detector.  This allows the primary and secondary image, which differ in intensity by several orders of magnitude, to both be detected on the same camera without over saturating the image.  The instrument works in compliance with ECE R43.  For  more information regarding this compliance, please view the presentation available below in the downloads section.
