Vega

The Vega light source is engineered for high‑precision camera measurements at extremely short exposure times, making it ideal for automotive‑grade imaging, HDR sensors, and contrast‑based performance testing. Its DC‑driven LED architecture delivers exceptionally stable illumination, ensuring repeatable CTA and CSNR results even under demanding fast‑exposure conditions.

Vega’s direct‑current intensity regulation eliminates the instability commonly seen in PWM‑controlled systems. By carefully selecting the LEDs and maintaining a thermally consistent operating point, Vega prevents color shifting, intensity fluctuations, and other artifacts that compromise measurement accuracy. The thermal system maintains ±0.5 °C stability, supporting both heating and cooling without drift, even when switching light sources or adjusting intensity.

To support real‑world testing scenarios, Vega provides advanced flicker generation across a wide frequency range, including sine, triangular, and square waveforms. This enables precise evaluation of camera behavior under modulated illumination, a critical requirement for modern automotive imaging systems.

Unlike PWM‑controlled light sources, which modulate intensity by rapidly switching LEDs on and off, Vega regulates intensity through current control, enabling fine‑grained adjustment and high‑intensity output at ultra‑short exposure times. This makes Vega particularly effective for HDR automotive cameras, where illumination stability directly impacts safety‑critical performance metrics.

For applications requiring even higher intensity and stability, explore the Arcturus light source.

Vega is an ideal solution for measuring Contrast Transfer Accuracy (CTA), Modulated Light Mitigation Probability (MMP), Contrast Signal-to-Noise Ratio (CSNR), or other high-intensity measurements outlined in the IEEE-2020:2024 standard. These factors are relevant to almost all automotive camera applications, which require test solutions capable of creating dynamic test scenes for cameras with very short exposure times.

The Vega is available in two separate hardware sets. Each set comes with a controller and control software. The controller can connect and control up to seven different Vega light sources. All of which can be programmed with the control software.

The Vega 1+1* is sold with one Vega light source and is perfect for those looking for a simple solution for testing HDR cameras with very short exposure times.

The Vega 3 + 1 Set* includes three Vega light sources and is a great solution for testing camera performance at varying flicker frequencies or for contrast transfer accuracy (CTA) measurements.

In addition to the sets listed above, we also offer individual Vega light sources as an “add-on” option for your project (an “add-on” does not come with a controller or control software).
