In this work we report on the characteristics of laser ignition of CH4-air mixtures, using multi-point (up to four points) ignition with single-pulse beams as well as with trains of two pulses. A compact Nd:YAG/Cr4+:YAG laser with four beams, each be

We report on multi-point laser ignition of air-methane mixtures in a static, constant-volume spherical chamber. A fiber-coupled diode-pumped, monolithic, passively Q-switched Nd:YAG/Cr4+:YAG composite ceramic laser with four-output beams, each beam c

The low-stress Solderjet Bumping technique was employed to assemble the optical components of an increased-robustness laser spark-plug ignition device using the low melting alloys 96.5Sn3Ag0.5Cu and 80Au20Sn. A finite-element-method analysis, optical

We present our experimental set-up and results for a THz beam profiling system based on a mechanical spatial light modulator (SLM) for one pixel sensing. By placing a synthetic aperture into the path of a propagating THz beam we achieved the optical

An optically multiplexed image camera often requires a photodetector for image sensing in conjunction with an optical multiplexer, such as a digital micromirror device or an amplitude spatial light modulator. For this type of camera, the advantages o

In dispersive spectroscopy, the measurements tend to be drowned in noise because of poor lighting conditions. Hadamard spectroscopy is a technique that allows better Signal-to-Noise Ratios (SNR) for the measurements. In this paper, we propose a metho

Compressive Sensing is an alternative to the acquisition and compression of sparse signals. One of the CS applications is the single pixel camera that reconsiders the conventional imaging systems. The key part of the camera is a Digital Micro-mirror

Although nowadays spectrometers reached a high level of performance, output signals are often weak and traditional slit spectrometers still confronts the problem of poor optical throughput, minimizing their efficiency in low light setup conditions. I
