slim13e FPGA mode capturing high velocity particles

Hello all,
I am working on a multi camera system based on slim13e, and CPP SDK version 2.3
I am trying to track particles in a test domain, and for this purpose, I illuminate the domain with multiple white stage LEDs
My problem is that I cannot get high velocity particle data from the cameras. I have a bar with 5 reflective marker on it, and the bar is rotating a t 66 RPM. Based on the markers distance from rotation center, they will have velocities from 0.2 to 3 m/s. Below is a sample image of a particle rotating at that velocity, and as seen, in some positions, the higher velocity particles are not captured. The camera is supposed to send 5 particles in all frames, but it doesn't happen. Does anyone know the cause? Thanks

If the cameras aren't capturing at a high enough frame rate, the fast-moving particles might not be recorded accurately. Did you try increasing the camera's frame rate and check if that reduces the issue?
