How the intensity of holography can be measured?
For measure of diffraction efficiency of holograms (DE) record the special test hologram of mirror (aluminium mirror, for example). The development process must be eliminating the change of thickness of emulsion layer.
The test hologram are illuminate by no extend laser beam and measure power of incident beam P1 and power of diffraction beam, P2. DE is calculating as P2/P1. All measures must be linear.
