This paper reports the mechanical design and optimization of tunable Fabry-Perot (FP) filter structures for the development of MEMS adaptive infrared detectors using finite element modeling and experimental investigations. The results indicate that the mechanical characteristics of the FP filters are significantly influenced by the structural designs, which eventually affect the filter performa...

Conventional diagnostic modalities for assessing arterial circulation or tissue perfusion include blood pressure measurement, ultrasound evaluation, and contrast-based angiographic assessment. An infrared thermal camera can detect infrared radiation energy from the human body, which generates a thermographic image to allow tissue perfusion analysis. We describe a smartphone-based miniature ther...

We report a surface-emitting THz source based on intracavity difference-frequency generation in dual-wavelength midinfrared quantum cascade lasers with integrated giant second-order nonlinear susceptibility. The THz light is coupled out of the waveguide by a second-order grating etched into the laser ridges. In contrast to sources where the differencefrequency radiation is emitted from the face...

We present complete near-infrared (0.85{2.45 m), low-resolution (100) spectra of a sample of 26 disk L-dwarfs with reliable optical spectral type clas-siication. The observations have been obtained with NICS at the TNG using a prism-based optical element (the Amici device) that provides a complete spectrum of the source on the detector. Our observations show that low-resolution near-infrared sp...

Exploiting the dependence of the refractive index on carrier concentration and temperature, various infrared laser probing techniques enable the experimental analysis of the carrier and heat flow distributions in the interior of semiconductor devices. In this work we present a complete numerical simulation sequence for the whole measurement process. It includes the electrothermal device simulat...

We report a hybrid up-conversion device integrating a In0.2Ga0.8As/GaAs MQWs photodetector with an organic light emitting diode (OLED), that converts input 980 nm infrared light to output 520 nm green light. Devices with different interface layer, used as the hole injection layer (HIL) in OLEDs were fabricated and tested. It was found that the device with an HIL of MoO3-doped CuPc exhibited a l...

Droplet microfluidics has emerged as a powerful platform allowing a large number of individual reactions to be carried out in spatially distinct microcompartments. Due to their small size, however, the spectroscopic characterisation of species encapsulated in such systems remains challenging. In this paper, we demonstrate the acquisition of infrared spectra from single microdroplets containing ...

While traditional image and video processing focus on extracting knowledge from data of a single modality, such as visual spectrum or thermal infrared video, this report investigates the benefits and challenges of capturing and analysing multimodal video. It specifically targets the two modalities of visible spectrum and thermal infrared video. A novel capture device has been developed to captu...

Installation work of large inner/outer wall panel glasses increases the labor load and stress of workers and causes the danger of such accidents as falling and crane overturning. To solve this problem, Gil designed the easy handling robot system which is composed of mobile system, 5-DOF manipulator system and HRI (Human-Robot Interface) device included HRC (Human-Robot Cooperation) algorithm. D...

The Transverse Field Detector (TFD) is a filter-less and demosaicking-less color sensitive device that easily allows the design of more than three color acquisition channels at each pixel site. The separation of light into different wavelength bands is based on the generation of transverse electric fields inside the device depleted region, and exploits the properties of the Silicon absorption c...
