The effect of change in scale and rotation of the signals in a lenslesa intensity correlator using Fresnel holographic filter has been considered both theoretically and experimentally. The experimental results show that it ia not sensitive to scale change and rotation. Thus it offers convenience in the application of certain pattern recognition.
