The paper describes an advanced multisensor demining robot. The robot transport system is based on a simple structure using pneumatic drive elements. The robot has robust design and can carry demining equipment up to 100 kg over rough terrains. Due to the adaptive possibilities of pedipulators to obstacles, the robot can adjust the working position of the demining sensors while searching for mi...

We present a detailed theoretical analysis on the quantum efficiency of a resonant cavity enhanced ~RCE! GaAs homojunction work function internal photoemission far-infrared ~FIR! detector. The quantum efficiency under both resonant and nonresonant conditions has been calculated. All the detector parameters are optimized under the realistically nonresonant condition. The further investigation of...

Mid-infrared detectors that are sensitive only in a tunable narrow spectral band are presented. They are based on the Resonant Cavity Enhanced Detector (RCED) principle and employing a thin active region using IV-VI narrow gap semiconductor layers. A Fabry-Pérot cavity is formed by two mirrors. The active layer is grown onto one mirror, while the second mirror can be displaced. This changes the...

A lead zirconate titanate (PZT;Pb(Zr0.52Ti0.48)O₃) layer embedded infrared (IR) detector decorated with wavelength-selective plasmonic crystals has been investigated for high-performance non-dispersive infrared (NDIR) spectroscopy. A plasmonic IR detector with an enhanced IR absorption band has been designed based on numerical simulations, fabricated by conventional microfabrication techniques,...

A new setup for direct microspectroscopic monitoring of singlet oxygen ((1)O2) has been developed in our laboratory using a novel near-infrared sensitive InGaAs 2D-array detector. An imaging spectrograph has been inserted in front of the 2D-array detector, which allows us to acquire spectral images where one dimension is spatial and the other is spectral. The work presents a detailed examinatio...

Objectives and Status—The original objectives of this project are two folded. One objective is to develop textured template for growth of epitaxial thin film ferroelectric (TFFE) IR detectors on polyimide coated Si. The commercial TFFE has a polycrystalline structure since it is directly grown on non-textured polyimide coating. This results in degraded device performance. The same problem also ...

Despite the rapid development of the quantum well ~QW! infrared technology, the intrinsic properties of the QW infrared photodetectors ~QWIPs! have not been directly measured under the operating conditions of the detector. In this work, we introduce a characterization technique, which utilizes the surface corrugation to probe the absorption coefficient and the photoconductive gain of a QWIP und...

Fourier transform infrared (FTIR) microscopic imaging uses a combination of an FTIR spectrometer with a microscope and Focal Plane Array (FPA) detector. The method has been recognized as a powerful and versatile imaging tool in many disciplines, ranging from biomedical research through to materials science, art conservation and forensics. The Field Of View (FOV) depends on both the magnifi cati...
