Scientists have designed a new type of high-speed imaging system that uses low-cost sensors and infrared illumination. The system is capable of capturing up to 500 frames per second, providing researchers with unprecedented detail of fast-moving objects. The system is based on a technique known as “time-resolved imaging”, which detects the change in intensity of an object as it moves. By illuminating the object with a pulsed light source and using a camera to record the changing intensity, researchers can accurately measure the speed and position of the object. The new system could have a wide range of applications, from studying the motion of flying insects to dynamic imaging of biological cells.
