Uroš Puc, Anton Jeglič, Gintaras Valušis
Doktorska disertacija
Oznake: teraherčna spekroskopija;teraherčno slikanje;optična zakasnilna linija;zdravila;eksplozivi;elektro-optični organski kristali;
In the past few decades terahertz (THz) technology has shown enormous progress practically in all areas. Among them, advances in ultra-fast laser technology contributed to major breakthroughs as THz generation and detection became possible by different physical mechanisms, like optical rectificat ...

An ability of lensless titanium-based antenna coupled microbolometers (Ti-µbolometers) operating at room temperature to monitor precisely radiation patterns in terahertz time-domain spectroscopy (THz-TDS) systems are demonstrated. To provide comprehensive picture, two different THz-TDS systems and T ...

Terahertz (THz) imaging and spectroscopy set-ups require fine optical alignment or precise control of spatial mode profile. We demonstrate universal, convenient and easy-to-use imaging—resonant and broadband antenna coupled ultrasensitive titanium-based—dedicated to accurately adjust and control spa ...

A terahertz (THz) imaging system based on narrow band microbolometer sensors (NBMS) and a novel diffractive lens was developed for spectroscopic microscopy applications. The frequency response characteristics of the THz antenna-coupled NBMS were determined employing Fourier transform spectroscopy. T ...
