Paper Abstract

We demonstrate a method of obtaining scale invariance detection using a white light optical correlator. We are able to detect different scaled versions of the target in the same scene up to a magnification factor equal to 2. Each scale factor is codified in a different wavelength so each scaled version of the target is detected with a correlation peak of different wavelength. Experimental results demonstrate the proposed technique and show the utility of the method here introduced.
