Abstract
A scanning technique for imaging sites in an array includes illuminating or irradiating sites in lines of the array, and collecting returned radiation from the sites for imaging. The sites are sequentially scanned by means of confocally directed radiation lines from source optics. The orientation of the radiation lines with respect to the lines of sites in the array is such that the distance between nearest edges of sites in adjacent lines is greater than lines through those edges in a direction parallel to the radiation lines used for scanning. The resulting system experiences less crosstalk and a greater ability to distinguish between neighboring sites in resulting images.
