Control of the formation and detection of on-axis and off-axis diffraction orders with two-level phase quantization of a vortex lens

Control of the formation and detection of on-axis and off-axis diffraction orders with two-level phase quantization of a vortex lens

The paper investigates the performance of a tilted vortex phase lens, quantized at a given level and allowing the generation of specified local maxima both on the optical axis and off it. A possibility of detecting individual diffraction orders and their combination is demonstrated. A combination of...
