Pondering
What is a reference beam?
Implications in optical encoding
Experimental Design
• Feasibility study
• Three levels:
– Transmission holograms with NJGSS procedure
– Transmission holograms with two object beams,
played back with objects intact
– Transmission holograms with two object beams,
played back with one object removed
• Analysis with ImageJ software
