Abstract

A new optoelectronic sensor whose spectral responsivity to UV radiation is almost identical with that of the human skin or of the eyes is presented. The sensor comprises two closely-spaced UV-sensitive Au-SiC diode, one of which is fitted with a glass filter. The photodiodes are connected to electronics that amplifies, combines and subtracts electrical signals generated by radiation in the photodiodes. The responsivity of the Au-SiC diode structure with a semitransparent gold electrode covers the whole UV spectrum, with the long-wavelength end bounded by the semiconductor bandgap. The photodiode with a filter absorbing wavelengths shorter than 315-320 nm is responsive in the UV-A region, while the difference between the electrical signals generated in the filter-containing and filter-free diodes is determined by the UV-B + IV-C radiation. The measuring of biologically effective radiation over the entire UV spectral range is achieved through combining the signal generated by UV-A radiation and the previously amplified difference signal generated by UV-B + UV-C radiation. The sensor spectral responsivity thus obtained is very close to the tabular curve of the relative spectral effectiveness of UV radiation on the normal human skin or eyes.
