Experimental output from a two-color pattern formation element (PFE). These are elements that generate intensity patterns in the focal plane formed from many closely packed focal spots. The PFE was fabricated in fused silica, with a period of 2mm. The photograph of the output is slightly over-exposed in an uneven manner for the two colors, so it fails to show the sharpness of the image that is observed in the laboratory. The size of the "red" image is approximately 1.5 times that of the "blue" image [see article by I.A. Barton, et al., for details].
