Backlight UnitsFrom computer keyboards to movie theaters, from car dashboards to fasten-seatbelt signs, backlit symbols are all around us. A backlit sign is, quite literally, lit from the back: an illuminated light source called a backlight unit (BLU) is placed behind a surface. Text and shapes cut into the overlaid surface allow light to shine through, creating bright, visible symbols.
Evaluating the accuracy of light and color across instrument clusters is a challenge compounded by several factors. The number of indicators, the varying location of symbols, and the range of colors on a panel prove complex for automated inspection systems and human inspectors alike.
In-dash flat panel displays, illuminated LED cup holders, puddle lights that cast logos from an open door to the pavement… The level of sophistication expected from today’s automotive technology captures the extent of automotive engineering innovation, while expectations regarding vehicle form and function is nothing short of perfection. A car is no longer a means to an end; a car has become an experience.
The TT-HUD module for TrueTest Software provides a test suite to efficiently perform light, color, and dimensional measurements used to evaluate the optical quality of head-up displays (HUD), including conventional, augmented reality (AR), and other HUD projection types.
The TT-NIRI module of TrueTest Software provides a test suite to efficiently perform high-resolution angular measurement of NIR light distributions, as well as dots in structured light patterns produced by diffractive optical elements (DOE).

Human perception is the ultimate standard for determining the visual quality of a device. However, the use of human inspection as a quality control method for development or production of devices is problematic because of the statistical variation between observers.
The VIP (Vision Inspection Pack) license for TrueTest Software supplements the standard photometric analysis capabilities of TrueTest Software with registration functionality for unique illuminated regions (backlit icons and shapes) to enable defect detection and accurate photometric measurement. This Spec Sheet features:
Absolute product quality has become a prerequisite to compete in a number of industries. Standard machine vision inspection systems are inadequate for detecting the subtle issues in high-end products that now dictate a manufacturer’s brand reputation. More sophisticated inspection technology is needed to replicate the acuity of the human user to see defects and anomalies. Advanced imaging solutions—such as scientific-grade CCD-based systems—offer the ability to inspect low-contrast regions in
Radiant technologies are thoughtfully engineered to achieve the fastest, simplest, and most accurate measurements of light, color, and surfaces. Imaging colorimeters and photometers leverage scientific-grade CCDs, high resolution, low noise, and factory calibration to ensure consistency of data across R&D to production. Utilizing photopic filters, Radiant cameras acquire absolute luminance and color information to qualify devices against human visual perception.
