| Abstract: | We report the formation of square, rectangular as well as hexagonal arrays of small light spots in one single setup using Michelson and Mach–Zehnder interferometers in tandem. The geometry of arrays can be altered easily online, by changing the relative orientations of the mirrors. The arrays could be scanned over large longitudinal distances and could be compressed to give large spot density. The expression for the resultant intensity distribution for the arrays has been worked out and the computed pattern is compared with the experimental data. |
