Abstract

We proposed a novel, fast, sub-pixel accuracy digital image motion estimation method, in Opt. Lett, 45(24), 6611- 6614 (2021). In this paper, we experimentally examine the method’s performance in more detail. Images are captured using both optical and THz imaging systems. A high-resolution megapixel camera is used in the optical system and a low-resolution camera with 16×16 pixel is used to perform the THz measurements. Both 1D x and y direction motion measurement data are examined and analysed. In all cases sub-pixel resolution is achieved. The results demonstrate that the method can be flexibly used in different areas.
