A resonant absorption cavity that couples long-wavelength infrared (LWIR) light into a movable plate has been demonstrated for thermal detectors, especially microbolometers. Each device is continuously tunable over 8.7-11.1 microm by using electrostatic actuation with voltages from 0 to 42 V. The width of the resonance is relatively broad, approximately 1.5 microm, to match the large widths of ...

The transient response of a nanoinjection infrared photon detector was studied by exploring the relation between lateral charge transfer and jitter. The jitter of the device was measured to be 15 ps at room temperature. The jitter was almost independent of the pulse power, even after device saturation. Spatial maps for delay and amplitude were acquired. The carrier velocity was extracted from t...

In recent years significant progress has been made in near-infrared single photon detection using Geiger-mode InPbased single photon avalanche diodes (SPADs). A more detailed understanding of these detectors with regard to device design, material growth and device fabrication has led to continual performance improvements. A variety of circuits for enabling SPAD Geiger-mode operation have been p...

We study an optomechhanical device supporting at least three optical modes in the infrared telecommunication band and mechanical vibration modes. model coherent driving of each mode, independently other, to obtain effective Hamiltonian showing different types parametric processes allowed device. propose a bichromatic scheme, lossy cavity regime, under mean field approximation, that provides qua...

BACKGROUND Moderate sunburn after prolonged sun exposure is thought to cause long-lasting inflammatory vasodilation due to thermal and ultraviolet radiation from the sun. We previously reported that near-infrared irradiation that simulates solar near-infrared can penetrate the skin and nonthermally affect the dermis, superficial muscles, and other tissues. To clarify the possible effect of near...

original article   one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf-magnetic field (mf) in substations, power plants, cities and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf meters. elf-mf was measured by tes-1394 mf tester (three-axis...

In this talk, I discuss the new physics and device applications provided by self-assembled quantum dots, in particular, with III-V compound semiconductor materials system. The quantum dots are the structures three-dimensionally confined and therefore provide quasi zero-dimensional electron gas system, where novel physics can be studied and improved device performance can be achieved, in particu...

The growth of the science and technology has a positive effect. One them is infrared, which employed as tool for therapeutic purposes. Based on observations at Puskesmas Kraton Yogyakarta, it known that there no new android-based infrared therapy device quality communication with patients still insufficient. In order to improve care provided patients, this activity aims increase value health pr...

BACKGROUND Infrared ear thermometry is frequently used in children, because this is a quick method of taking temperature and the ear is easily accessible. Our aim was to evaluate agreement between temperature measured at the rectum and ear in children. METHODS We did a systematic review of studies comparing temperature measured at the rectum (the reference site) using mercury, electronic, or ...
