Infrared scene projectors (IRSPs) are a critical laboratory tool for setup, testing and calibration of infrared imaging systems. These projectors create an infrared scene of precisely known characteristics. The projector typically uses a single chip infrared emitter array to produce actual infrared imagery. A promising device technology for building emitter arrays is infrared light emitting dio...

In the area of Human-Computer Interaction (HCI), the concept of Around Device Interaction (ADI) is gaining special attention nowadays. It provides the possibility of interacting with the device by making use of gestures made in the surrounding space, as well as by detecting certain ambient changes, thus eliminating the need of direct physical contact. Contact-free interaction can be useful for ...

We describe the control and performance of a new near-infrared camera based on a Rockwell PICNIC array detector for interferometry observations at the Infrared-Optical Telescope Array (IOTA). The camera control uses a complex programmable logic device that allows fast and stable clocking of the PICNIC array and on-the-fly reconfiguration of the readout method. We measured a read noise as low as...

This paper introduces a fast infrared spots detection algorithm designed for field-programmable gate array (FPGA) implementation. The proposed algorithm processes four pixels per clock cycle and detects infrared spots in a single pass over a frame. The implementation of the algorithm is only composed of combinatorial logic and registers. Furthermore, the execution time of the algorithm is indep...

Functional near-infrared spectroscopy (fNIRS) is the promising non-invasive technique for brain-computer interface (BCI) for brain signal acquisition. Wearable multi-channel fNIRS devices that can provide much comport for applications and researches are commercially available in the market recently. In this study, we research possibility of the wearable multi-channel fNIRS device by evaluating ...

We present a novel needle-based device for the measurement of refractive index and scattering using low-coherence interferometry. Coupled to the sample arm of an optical coherence tomography system, the device detects the scattering response of, and optical path length through, a sample residing in a fixed-width channel. We report use of the device to make near-infrared measurements of tissues ...

in this research nanoparticles of nickel (ii) chloride were synthesized and characterized using fourier transform infrared (ft-ir) spectra. nanoparticles of nickel (ii) chloride were prepared by using of ball mill device. a ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. in the researc...
