TrueTest Automated Visual Inspection Software

When testing the quality of illuminated components and displays, or looking for defects in assemblies and surfaces, multiple tests may need to be performed to inspect products for a range of evaluation criteria. Radiant’s TrueTest™ Software equips ProMetric® Imaging Colorimeters and Photometers to be used for in-line inspection, providing:

• a comprehensive set of predefined tests,
• a flexible framework that allows you to apply a single test or sequence of tests as needed, quickly and efficiently, and
• a pass/fail report with as much detail as you need.

The TrueTest software application has five main components:

• Test library
• Test sequencer
• Test manager (user-defined test parameters and pass/fail settings)
• Test execution, automated
• Report generator

Any tests from the test library can be added to a test sequence (these are stored, so multiple sequences can be created and recalled as needed), and test parameters and pass/fail settings are input for each test. Then the entire sequence is run end-to-end automatically. Individual test results are displayed and can be recorded in a report.

Provided with TrueTest are a range of standard quality tests and defect detection tools, including:

• ANSI Brightness
• ANSI Color Uniformity
• Autofocus
• AutoPOI
• Checkerboard Contrast
• Chromaticity
• Color Edge Mura
• Color Mura
• Compare Points of Interest
• Diagonal Pattern Mura
• Distortion
• Focus Uniformity
• Gradient
• Line Defects
• Particle Defects
• Pixel Defects
• Points of Interest
• Polarizer Deformation
• Random Mura
• Sequential Contrast
• Spot Pattern Mura
• Uniformity

Additional advanced mura detection tests are available in optional software modules that add additional mura analysis, headlamp test parameters, head-up display tests, AR/VR display tests, and other application-specific measurements.
