How Event-Based Vision Is Redefining Defence & Aerospace Operations When the threat is airborne, uncertainty is the enemy. In contested airspace, the difference between mission success and mission failure often comes down to milliseconds, how quickly a system can detect a fast-moving object, classify it, and hand off a decision to the operator or the platform itself. Traditional camera systems, built for capturing scenes rather than reacting to them, are increasingly strained by this demand. Small drones move fast and erratically. Adversaries operate in degraded, GPS-denied, and electronically contested environments. And every gram and milliwatt added to a platform’s sensor payload comes at a real operational cost. This is the problem event-based vision was built to solve. What Makes Event-Based Vision Different Conventional cameras capture the world in frames, full images taken at fixed intervals, whether or not anything in the scene has changed. This approach works well for photography, but it’s fundamentally mismatched to the demands of defence and aerospace sensing, where the moments that matter most are exactly the ones that happen between frames. Event-based vision flips the model. Instead of capturing full frames on a clock, each…

High-Speed Cameras for Fluid Dynamics: Applications & Benefits Fluid dynamics involves some of the fastest and most complex phenomena in engineering and scientific research. Droplets break apart in milliseconds, bubbles can collapse almost instantaneously, and turbulent flow can produce constantly changing vortices and instabilities. These events are often too fast for the human eye and conventional cameras to capture in meaningful detail. High-speed cameras provide a way to make these transient events visible. By recording thousands of frames per second and playing the footage back in slow motion, researchers and engineers can observe how a fluid behaves from one moment to the next. Chronos High Speed Cameras offer a practical imaging solution for a wide range of fluid dynamics applications, from droplet and spray analysis to cavitation, jet breakup and turbulence studies. Why High-Speed Imaging Matters in Fluid Dynamics A conventional video camera may capture an event at 30 or 60 frames per second. While this is sufficient for everyday video, it can be inadequate for studying rapidly changing fluid behavior. Consider a droplet striking a surface. The entire process, from initial impact to spreading, splashing and the formation of…

SWIR Cameras with Zoom Lenses: A New Approach to Long-Range Surveillance Long-range surveillance has traditionally relied on visible cameras, Long-Wave Infrared (LWIR), and Mid-Wave Infrared (MWIR) imaging systems. Each technology has its strengths, but the requirements of modern surveillance are changing. Security teams increasingly need higher resolution, longer-range identification, better performance in challenging visibility conditions, and systems that can deliver these capabilities without the cost and complexity associated with high-end thermal imaging. This is where Short-Wave Infrared (SWIR) cameras with high-performance zoom lenses are gaining attention. By combining high-resolution SWIR sensors with long-focal-length optics, it is possible to build surveillance systems capable of delivering highly detailed monochromatic imagery at extremely long distances. In some configurations, SWIR lenses can reach focal lengths of up to 2,500 mm, opening up new possibilities for border security, maritime surveillance, critical infrastructure protection, and other long-range observation applications. What Is SWIR Imaging? SWIR, or Short-Wave Infrared, generally refers to infrared wavelengths around the 0.9–1.7 μm range in commonly used InGaAs-based cameras. It occupies a position between visible/NIR imaging and traditional thermal infrared technologies such as MWIR and LWIR. One of the most important differences is…

Particle Image Velocimetry (PIV): How Chronos High-Speed Cameras Enable Accurate Flow Analysis Understanding how fluids move is fundamental to improving the performance of aircraft, automobiles, industrial machinery, and even medical devices. Engineers and researchers rely on precise flow measurement techniques to analyze velocity, turbulence, mixing, and aerodynamic performance. Among the many available methods, Particle Image Velocimetry (PIV) has become one of the most trusted optical techniques for capturing detailed flow behavior without disturbing the fluid itself. At the heart of every successful PIV system is a high-speed camera capable of capturing rapidly moving particles with exceptional clarity and precision. In this article, we’ll explore what Particle Image Velocimetry is, why high-speed imaging is essential, and how Chronos High-Speed Cameras provide a practical and cost-effective solution for many PIV applications. What is Particle Image Velocimetry (PIV)? Particle Image Velocimetry (PIV) is a non-contact optical measurement technique used to visualize and quantify the velocity of fluids. Instead of inserting probes or sensors into the flow, PIV uses microscopic tracer particles that faithfully follow the movement of the fluid. The process begins by introducing these particles into the liquid or gas under investigation….

A Practical Guide to Near-Infrared Cameras for Machine Vision Near-infrared, or NIR, cameras are becoming increasingly important in modern machine vision systems. While standard cameras operate in the visible light spectrum, NIR cameras are designed to capture wavelengths just beyond what the human eye can see. This capability allows them to reveal details that are otherwise hidden, making them valuable in industrial inspection, research, medical imaging, and automation. In many environments, visible light imaging is not enough. Materials may look similar in color but behave very differently under near-infrared light. Certain defects, moisture content, or contaminants may not be visible in the standard spectrum. NIR cameras solve this problem by providing enhanced contrast and deeper insight into materials and processes. What Is Near-Infrared Imaging Near-infrared light sits just beyond the visible spectrum, typically between 700 nm and 1000 nm, although some sensors can detect even further into the infrared range. Human eyes cannot detect this light, but specially designed sensors can capture it and convert it into a usable image. In a typical machine vision setup, a NIR camera is paired with a light source that emits near-infrared wavelengths. The…

What Are High Speed Cameras: A Comprehensive Guide If you have ever wondered how filmmakers capture a bullet piercing glass, how engineers study car crash impacts, or how scientists analyse the motion of a hummingbird’s wings, the answer lies in high speed cameras. These specialized imaging systems record motion at thousands or even millions of frames per second, revealing details too fast for the human eye or a normal camera to detect. In this guide, we break down what high speed cameras are, how they work, and the key technologies that power them. What Is a High Speed Camera? A high speed camera is designed to capture video at extremely high frame rates far beyond the 24 to 60 fps recorded by most consumer or professional video cameras. Depending on the model, a high speed camera may capture anywhere from 1,000 fps to more than 1,000,000 fps. At these speeds, events that normally occur in an instant such as a droplet hitting a surface, an airbag deploying, or a manufacturing defect can be slowed down and analyzed in great detail. This makes high speed cameras indispensable in research, engineering, production,…
