Abstract The transmission spectra of whole blood have been studied by the time-domain THz spectroscopy in the frequency range from 0.3 to 0.5 THz. Biosamples produced from the same person with the diabetes mellitus during a short time period after the insulin injection have been used. Frequency dispersions of blood optical properties are obtained. Based on frequency dispersions, the dependences of blood glucose concentrations with the refractive index and permittivity are presented. This work is a part of the complex investigation, that focuses on the development of a non-invasive glucose measuring technique. Registering dependences between blood glucose level and blood optical parameters allows for the non-invasive spectroscopy to be used in the reflection mode for glucose testing.
