Coding Two‐Dimensional Images with Orbital Angular Momentum of Light-Image

We consider decoding of two‐dimensional information encoded with orbital angular momentum (OAM) of light. Spiral phase plates and spatial light modulators are used to prepare encoding and decoding OAM states, respectively. We show that with selective coding OAM states, off‐axis points and spatial variables encoded with OAM are reproducible.
