Description
Summary:A new method for the recording of a microwave field using a moiré interference pattern is presented. The moiré interference pattern was used to map the thermal expansion of a microwave absorbing slab when irradiated by a microwave field. The technique was evaluated by applying it to the recording of a number of different microwave holograms. The moiré recording method is found to be relatively sensitive and usable to produce holographic images of good quality.
