Arcturus
Illumination

Today’s image sensors and high-dynamic-range configurations make testing at or near sensor saturation challenging. With Arcturus, we can generate more than enough intensity to challenge these sensors, with a sensitivity much higher than currently possible, making it a powerful addition to the Vega line. This device is ideal for evaluating many of the key performance indicators (KPIs) outlined in the IEEE-2020 standard for image quality performance in automotive applications. KPIs include contrast metrics such as contrast transfer accuracy (CTA), contrast-to-noise ratio (CNR), and flicker or modulated light mitigation probability (MMP).

Arcturus can be combined with other Vega devices to create a dynamic test scene. In addition, it can be integrated into the Versatile Light System (VLS) to increase scene intensity. With this combination, you can create a real-world automotive test scene, with the Arcturus simulating direct sunlight and other high-intensity light sources, and the Vegas simulating ambient light sources (e.g., headlights, traffic lights).

Automotive-grade camera systems must be tested in numerous light environments, particularly those following the newly established IEEE-2020 standard. One of the more challenging scenarios to test for is how the camera system will perform in direct, bright sunlight, as this level of intensity is often difficult to generate in a test lab. Arcturus can simulate the intensity of bright sunlight illumination with very high stability compared to other light sources. This ability allows camera systems to be evaluated in a test lab more efficiently.
