Dynamic speckle analysis (DSA) is a non-contact method to obtain the motion information about the inspected sample. Conventional implementations analyze the speckle patterns from time-varying intensity frames using frame-based sensors such as a complementary metal oxide semiconductor (CMOS) and charge-coupled device (CCD). Here, we propose to use the event sensor which measures pixel-wise asynchronous brightness changes to record speckle pattern sequences. Our approach takes advantage of the low latency and high contrast sensitivity of the event sensor to implement DSA with high temporal resolution. Experimental results show that the event-based representation is a new optimal solution for DSA especially for high speed applications.
