High-speed camera "MEMRECAM ACS-3"

【Advanced Research Supporting Aircraft Lightning Protection Technology】 Aircraft may pass through thunderstorm areas during operation and are estimated to be struck by lightning 1 to 2 times per year. In recent years, the adoption of CFRP (carbon fiber reinforced plastic), a lightweight and high-strength material, has been advancing in aircraft. However, it has the challenge of lower electrical conductivity compared to metals, making it easier for lightning currents to concentrate locally. Professor Hiroki Saito from the Advanced Materials Strength Science Research Center at Tohoku University conducts artificial lightning strike tests aimed at improving the lightning resistance of CFRP, analyzing damage behaviors such as arc discharge, resin decomposition, and interlayer delamination. To capture phenomena that change on a microsecond scale during the tests, high-speed cameras from NAC are used to visualize the moment of the lightning strike with high precision, advancing the acquisition of foundational data that contributes to the safety enhancement of next-generation aircraft. 【For case studies, click here】 https://www.nacinc.jp/column/category/20260422.html

In March 2025, we released the latest firmware Ver. 2.18 for the MEMRECAM ACS-1 and ACS-3, which we manufacture and sell. ■ Activation of Black and White Boost Mode for Color Camera Models The "Black and White Boost Mode," which was previously only available for black and white camera models, can now also be used with color camera models. ■ Quality Priority Mode This feature allows for high-quality shooting by significantly reducing noise by limiting the camera's maximum sensitivity. It captures details of the subject clearly while maintaining brightness and darkness, making it ideal for image analysis such as PIV and DIC. ■ Increased Shutter Speed The shutter speed during shooting has been increased, achieving a maximum exposure time of 100ns for the ACS-1 and 400ns for the ACS-3. ■ Increased Resolution for High-Speed Shooting Previously, when shooting at 400,000 frames per second in the boost mode of ACS cameras, the maximum recording resolution was 1,280×192. By updating to Ver. 2.18, the vertical resolution increases by an impressive 67%, allowing shooting at a resolution of 1,280×320.

We are pleased to announce that we will be hosting a seminar on packaging testing technology, organized by Shin-ei Technology Co., Ltd. To optimize packaging design, various tests and measurements are necessary, including quantifying the transportation environment, assessing product impact durability, selecting cushioning materials, structural design, and conducting packaging cargo tests. In this seminar, four related companies will come together to provide specialized techniques to support appropriate packaging design from the following perspectives: - Concepts of appropriate packaging design and specific examples of product durability testing - Simulation analysis techniques in the design process - High-speed image analysis to support packaging cargo testing - Latest trends in transportation vibration testing This seminar will be conducted as a web seminar using Zoom. Live presentations will be broadcast on September 18 (Wednesday), with recorded videos rebroadcast on September 25 (Wednesday) and October 8 (Tuesday). After registration, you will automatically receive a confirmation email containing the participation URL. *Please note that participation from competing companies may be declined.

NAC Image Technology will exhibit at the "Automotive Engineering Exposition 2024 YOKOHAMA" held at Pacifico Yokohama from May 22 (Wednesday) to May 24 (Friday), 2024. We will showcase visualization methods used in automotive development utilizing "high-speed cameras," "gaze measurement devices," and "motion capture," as well as our unique quantitative analysis system based on years of image analysis technology. We will propose measurement tools suitable for improving "safety," "fuel efficiency," and "comfort" through video analysis. Additionally, we will display the Active Safety (AD/ADAS) testing evaluation tools from the German company MESSRING. We sincerely look forward to your visit.
