摘要:
The present invention relates to a method of recording data in digital form on a write-once read-many optical medium comprising a sensitive film based on a metal oxide of the oxidizable spinel type. Regions of the sensitive film are heated, locally and in succession, under conditions allowing oxidation of the oxidizable metal ions of the oxide. In the optical medium thus recorded, the virgin regions, which are not modified by the write operation, are oxidizable and change color after heat treatment in an oxidizing atmosphere.
摘要:
The invention relates to the use of a material having a spinel ferrite/iron monoxide structure as a sensitive material in the form of a thin film for the bolometric detection of infrared radiation, the chemical composition of said structure, excluding doping agents that may be present, having empirical formula (I): (Fe1−zMz)xO, where x is strictly less than 1 and strictly greater than 0.75. The invention also relates to a bolometric device for infrared radiation detection and infrared imaging, comprising at least one sensor provided with a sensitive element in the form of a thin film as defined above.
