Abstract

The pyroelectric detectors on the basis of systems: thin nickel film--thick lithium niobate substrate, thin molybdenum film--thick lithium niobate substrate and thin titanium film--thick lithium niobate substrate implanted by argon ions as sensitive elements were designed. The optical constants of such systems with film thicknesses of d=15, 20, 30, and 40 nm in the wide spectral range were measured. It is shown that the reflectance of the system thin nickel film--lithium niobate increases and the reflectance of the systems thin molybdenum film--thick lithium niobate substrate and thin titanium film--thick lithium niobate substate decreases owing to the implantation. The influence of ion implantation on the surface structure of such systems is studied by electron microscopy. The optical characteristics and the functional parameters of pyroelectric detectors such as spectral sensitivity, radiation stabilty are researched. The number of advantages of such pyroelectric detectors among other detectors of similar type is found.
