Evaluating backlit components—such as illuminated controls, instrument panels, and LED light strips—requires a unique measurement approach. The quality of an illuminated component is determined as much by its photometric qualities (brightness, color) as it is by the overall integrity of its illuminated regions (correct shape, free from defects). Accurate measurement requires precise registration of icons and shapes, ensuring that only the illuminated region is used to quantify photometric values and that defects can be detected.
Radiant solutions are unique in offering the precision of our patented ProMetric calibration technology to combine photometric light measurement with advanced machine vision tools. Manufacturers of automotive dashboards and controls, avionics cockpit panels, backlit keyboards, and illuminated signage can benefit from powerful integrated solutions for automated inspection of backlit characters and symbols.
Characteristics such as luminance, contrast, character shape and completeness (no exclusions of inclusions), position/orientation, and validation (is it the correct letter/number) can all be assessed simultaneously from a single image using our ProMetric imaging photometers and colorimeters with purpose-built software such as Vision Inspection Pack (VIP™) and Aerospace Character Evalutiont (ACE) with integrated OCR. Robust quantitative analysis and reporting enables customers in regulated industries such as automotive and aerospace to capture the data they need to ensure compliance with requirements.
