Vega (Illumination Device)

多功能的直流驅動光源，
可滿足所有相機測試要求

Vega 是我們最新的光源設備之一，使用直流電技術來創建高穩定性光源。 DC 技術可使所有攝像頭測試受益，包括配合曝光時間極短的攝像頭進行測試。

例如車載相機測試時，由於測試設備性能不足，經常會遇到光源穩定性問題。

– 高動態範圍測試
– 極短的曝光時間測試
– 光源極其穩定
– 多種 Flicker 模式

該設備非常適合那些希望擁有高精確性測量解決方案的用戶，例如對比度檢測概率 contrast detection probability (CDP)，調制光緩解概率 modulated light mitigation probability (MMP)，噪聲和色調曲線測量。

The Vega light source presents a solution for high precision measurements of exceedingly short exposure times often seen in automotive-grade cameras. Vega uses LEDs that are driven by DC (direct current) technology making it one of our most sophisticated and unique light sources ever developed.

Cameras with very short exposure times often experience stability problems due to inadequate testing devices. Vega has extremely high stability that provides a previously unattainable consistency for measuring these types of cameras.

While we do use DC technology for this device, we are able to eliminate color shifting through the meticulous selection of the LEDs. The DC driver does not affect temperature regulation and we can achieve temperature stability within half a degree. The temperature system works both ways (i.e., heating and cooling) and it will remain consistent even when turning on/off different light sources or changing the intensities.

Vega also has advanced flicker capabilities and can be generated from a wider frequency range. We have also further developed the low-frequency functionality to include sine, triangular, and square waveforms, which allows us to cover nearly all real-world scenarios.

Why Vega?

Unlike PWM controlled light sources, where intensity is regulated by the high-frequency of switching the LEDs on/off, Vega regulates the intensity by the amount of current. Vega offers 1,000,000 equal-width steps for intensity control. These feature allows the Vega to measure high intensities with extremely short exposure times. HDR cameras from the automotive sector benefit greatly from this technology as they require the highest level of performance to ensure safety.

When to use Vega?

Vega will best be utilized when measuring Contrast Detection Probability (CDP), Modulated Light Mitigation Probability (MMP), OECF, or other high-intensity measurements. All of these factors are relevant to the automotive sector, but also apply to other sectors that have high demands on accuracy.

Vega software

Vega is sold with included control software that will allow you to control up to seven Vega devices at one time. An API is also available (sold separately) for smooth integration into individual designs.

Vega hardware

The Vega is available in three 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 Starter Set* 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 Flicker Set* is sold with three Vega light sources and is for those searching for a solution to test camera performance against varying flicker frequencies.

The Vega CDP Set* is sold with seven Vega light sources (maximum amount for one controller) and is the perfect solution for testing the overall CDP performance of an automotive camera system.

In addition to the three 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).
