Versatile Light System

The VLS (Versatile Light System) is a versatile illumination solution that efficiently measures a wide range of image quality factors, including contrast transfer accuracy (CTA), modulated light mitigation probability (MMP), and contrast signal-to-noise ratio (CSNR). The setup, powered by six Vega light sources, creates a dynamic scene that can be quickly rearranged to simulate typical illumination challenges for automotive cameras and sensor systems.

Vega light source

The Vega light source uses DC technology to deliver a high-stability output with flicker-generation capabilities. DC technology benefits all camera testing, including tests with very short exposure times, such as automotive-grade cameras.

VLS Hardware setup

The VLS is a system of six Vega devices, each connected to an individual arm*. All Vegas are linked via the arms to a tripod, offering high adaptability. The arms' flexibility allows each Vega to be moved to generate a range of configurations and angles during testing, providing versatile testing capabilities.

We offer a product package that includes Vega light sources (up to six) and the flexible mounting option for creating dynamic test scenes. The cost varies depending on the number of light sources and mounting options. Contact our sales team for pricing details.

This product is not automated; each arm of the VLS must be manually moved and set. However, during the product development, a manual setup proved faster and more efficient than full automation.

Test Charts

Additionally, we offer grayscale test charts designed for use with Vega devices. The chart is a transmissive gray step chart with 36 patches and a 10:1 contrast. It magnetically attaches to the front of the Vega light source, thereby ensuring uniform illumination. Charts are sold separately.

*The mounting system is sold separately. We use third-party products to enable our customers to create flexible setups. The arm and tripod are third-party products, and the setup shown is an example of how the user can set up the light sources using them.

Measure most of the KPIs from the IEEE-2020 standard, including CTA, CSNR, MMP, and dynamic range.

Create a dynamic test scene using individual arms to move and place light sources at different angles.

VLS utilizes multiple Vegas, powered by DC technology, to generate illumination.

The Vega light source offers advanced flicker capabilities across a wider frequency range.

The VLS supports both spatial and temporal recording measurements as outlined in the IEEE-2020 standard.

The VLS has unique control and evaluation software. Vega APIs are also available.

The control software generates illumination test sequences for the Vega devices. The software can control up to six Vega devices at once. The measurement values are used to create a reference file for evaluation during testing. Sequences can be saved as XML files for future use. The VLS software is sold separately from the VLS hardware.

The evaluation software analyzes the camera's performance using the defined IEEE-2020 KPIs, including CTA, MMP, and CSNR. CTA evaluations are based on the pixel value distributions. Results are exported as XML files. The VLS software is sold separately from the VLS hardware.

Spatial recording measurements are faster and are suitable for systems that are unsuitable for temporal measurements due to lens effects or dynamic image processing (e.g., auto-exposure). The VLS now supports both spatial and temporal recording measurements, as outlined in the IEEE-2020 standard. Test results can be used to evaluate your camera system's CTA (contrast transfer accuracy), CSNR (contrast signal-to-noise ratio), and dynamic range performance.

Temporal recording measurements allow you to capture one image per luminance step, avoiding flare that often occurs during camera alignment to a light source. he VLS now supports both spatial and temporal recording measurements as outlined in the IEEE-P2020 standard. Test results can be used to evaluate your camera system's CTA (contrast transfer accuracy), CSNR (contrast signal-to-noise ratio), and dynamic range performance.
