Vega

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.

Vega 光源為汽車級相機中常見的曝光時間極短的高精度測量提供瞭解決方案。Vega 採用直流（DC）技術驅動 LED，是我們迄今為止開發的最精密、最獨特的光源之一。

曝光時間極短的照相機通常會因測試設備不足而出現穩定性問題。Vega 具有極高的穩定性，為測量這類相機提供了以前無法實現的一致性。

雖然我們在該設備中使用了直流技術，但通過對 LED 的精心選擇，我們能夠消除色差。直流驅動器不會影響溫度調節，我們可以實現半度以內的溫度穩定性。溫度系統可雙向工作（即加熱和冷卻），即使在開啓/關閉不同光源或改變強度時，也能保持穩定。

Vega 還具有先進的閃爍功能，可以產生更寬的頻率範圍。我們還進一步開發了低頻功能，包括正弦波、三角波和方波，這使我們能夠覆蓋幾乎所有的實際應用場景。

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 features allow 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 Transfer Accuracy (CTA), 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 is also a much more compact and flexible solution compared to the previous DTS solution.

Vega software and APIs

Vega is sold with included control software that will allow you to control up to seven Vega devices at one time. APIs also available (sold separately) for smooth integration into individual designs. We offer a C, C++ and Python API.

Vega charts (TE294)

The TE294 chart is optimized to work with Vega. It is a unique grayscale test chart for high precision measurements, including Contrast Transfer Accuracy (CTA) and other contrast-based performance indicators. We offer a few chart variations apart from the standard grayscale chart. Please contact our sales team for more details. Charts are available individually or in sets. As with the Vega light source, you can purchase charts as a one-piece set, three pieces, or seven pieces.

Please note, that the TE294 charts are always sold separately from the Vega light source.

Vega hardware

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* is sold with three Vega light sources and is a great for a solution to test camera performance against varying flicker frequencies or contrast transfer accuracy (CTA) measurements.

In addition to the two 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).

為什麼選擇 Vega？

PWM 控制光源通過高頻率開關 LED 來調節強度，而 Vega 則不同，它通過電流大小來調節強度。Vega 提供 1,000,000 等寬步長的強度控制。這些特點使得 Vega 能夠在極短的曝光時間內測量高強度。汽車行業的 HDR 攝像機需要最高級別的性能來確保安全，因此從這項技術中獲益匪淺。
何時使用 Vega？

在測量對比度傳遞精度（CTA）、調制光減弱概率（MMP）、OECF 或其他高強度測量時，使用 Vega 的效果最佳。所有這些因素都與汽車行業相關，但也適用於對精度要求較高的其他行業。與之前的 DTS 解決方案相比，Vega 也是一個更加緊湊和靈活的解決方案。
Vega 軟件和應用程序接口

Vega 在銷售時附帶了控制軟件，可以同時控制多達七台 Vega 設備。我們還提供 API（單獨銷售），以便將其順利集成到個性化設計中。我們提供 C、C++ 和 Python API。
Vega 圖表（TE294）

TE294 圖錶針對 Vega 進行了優化。它是一種獨特的灰度測試圖表，用於高精度測量，包括對比度傳遞精度（CTA）和其他基於對比度的性能指標。除標準灰度測試圖外，我們還提供其他一些測試圖。詳情請聯繫我們的銷售團隊。
