Abstract
A diamondlike carbon thin film protected hologram comprises an organic film deposited on a substrate and recorded to form a hologram, and a diamondlike carbon thin film deposited on the hologram, or first and second substrates having a diamondlike carbon thin film deposited thereon and an organic film having a holographic pattern recorded therein and sandwiched between the diamondlike carbon thin films of the first and second substrates. A method of fabricating a diamondlike carbon thin film protected hologram comprises forming a layer of dichromated gelatin on a substrate, recording the dichromated gelatin to form a hologram, and depositing on the hologram a diamondlike carbon thin film at room temperature, or depositing a diamondlike carbon thin film on first and second substrates, forming a layer of dichromated gelatin on the thin film of one of the substrates, recording the layer to form a hologram, and adhering the thin film of the second substrate to the hologram. The diamondlike carbon thin film protected hologram of the present invention is impervious to moisture and humidity and other environmental conditions which would otherwise negatively affect the performance of the hologram.
