TrueTest Automated Visual Inspection

Quality testing and defect detection


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

They provide:

  • 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
  • A pass/fail report with as much detail as you need

Current Version:
Ver. 1.8.2148.22

Supported Products:

  • ProMetric Y Series Photometers: Y2, Y16, Y29, Y43, Y45, Y61
  • ProMetric I Series Colorimeters: I2, I8, I16, I29, I61

System Requirements:

  • 3.0 GHz and 8 cores
  • 16-32 GB RAM
  • Windows® 7or 10, 64 bit
  • Dual-monitor video output
  • Ethernet 100/1000 or USB 2.0

Turnkey system for automated visual inspection
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

TrueTest is easy to use. 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 you can input test parameters and pass/fail settings 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.

Extensive selection of quality tests built-in
Provided with TrueTest are a range of standard quality tests and defect detection tools, including:

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

Additional advanced mura detection tests are available in the optional TrueMURA™ module.

Designed for high-volume manufacturing applications

  • While TrueTest can be used for diagnostic testing of a device in a laboratory setting, it is designed to meet the demands of high-volume manufacturing applications:
  • Supports both an administrator interface for defining tests and test parameters, and a restricted operator mode for running tests
  • Interfaces to a video pattern generator or the device under test itself to control test patterns
  • Tests can be initiated by a human operator or directly by a production control system (PCS) in a fully-automated production environment
  • Interfaces to the PCS, a barcode reader, or the equivalent equipment to obtain information about the device under test (DUT); the test sequence and test parameters can be varied automatically from DUT to DUT based on this information
  • Takes advantage of the high-speed computing technology of modern PCs to take measurements and perform test analyses in parallel, thereby minimizing cycle time

Part of a field-proven system for production testing
TrueTest Software is combined with any ProMetric Imaging Colorimeter or Photometer to create a complete testing system for light quality measurement or machine vision. The specific ProMetric imaging product chosen will depend on your application’s requirements for resolution, accuracy, and cost.

When you install TrueTest, Radiant Vision Systems application engineers will work with you to integrate and initialize the system, and train you how to perform those operations and how to maintain the system.

The TrueTest product family is field-proven, with installations worldwide, testing millions of devices for a broad range of products. Radiant will support your integration with our global technical support team and distributor network.

Available in application-specific modules

TrueTest Software is also available in unique test suites, aligned to and further developed for application-specific testing—from automotive head-up display measurement to in-headset AR and VR display testing. Find a module as unique as your application:
