Abstract
An experimental study on geometrical thickness measurements of photoco nductor polymer coatings on thermoplastic polyester film substrate use d as commercially available recording holograms is reported. The bases of these measurements which enable the evaluation of both total and c oating thicknesses are the interference visible and infrared absorptio n spectra and the absorbance value of a band caused by the photoconduc tor coating in the infrared spectrum. A new technique, based on the La mbert-Beer law is proposed in order to obtain the thickness measuremen t of the coating.
