A new speckle velocimeter using the cross‐correlation method was developed. Its optical system achieved wide working distance range of ±5mm and small measuring errors for various materials. Furthermore the realtime correlation processor for the clipped signals makes the cross‐correlation method applicable to in‐line measurement in factories.
