Photon Counting Optical Time Domain Reflectometry Applying a Single Photon Modulation Technique
Chinese Physics Letters, 2011Photon-counting optical time domain reflectometry (v-OTDR) is typically used in a mode with spatial resolution in the centimeter range. Here we demonstrate a 1550nm v-OTDR system to optimize the discriminate voltage of a single photon avalanche detector using a single photon modulation and demodulation technique, which shows obvious improvement in the ...

2018 Asia Communications and Photonics Conference (ACP), 2018
A photonics-based multiband radar is proposed based on an optical frequency sweeping comb and photonic dechirp receiving. The proposed radar has a simple structure, and it is capable to simultaneously generate and process multiple linear frequency modulation (LFM) signals in different frequency bands.

Two-photon-based structured illumination microscopy applied for superresolution optical biopsy
SPIE Proceedings, 2013Combining the concept of structured illumination with two-photon microscopy, two-photon grid scanning pattern microscopy (TP-GPSM) was demonstrated to provide optical section power due to two-photon excitation and super-resolution in lateral through structured illumination.

Photon migration theory applied to 3D optical imaging of tissue
Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society, 2002Noninvasive optical spectroscopic imaging of tissue has considerable potential for clinical screening and monitoring metabolic status, if accurate tomographic reconstruction techniques are developed. The rationale for specific diagnosis is based on different spectroscopic signatures of intrinsic tissue or specific exogenous labels which can distinguish

Multi-dimensional time-correlated single photon counting applied to diffuse optical tomography
SPIE Proceedings, 2005We present a multi-dimensional TCSPC technique that combines multi-detector and multiplexing capability, and records fast and virtually unlimited sequences of time-of-flight distributions. The system consists of four fully parallel TCSPC channels. Each channel records simultaneously in up to eight detection channels.

Applying optical design methods to the development of application specific photonic crystal fibres
SPIE Proceedings, 2012Photonic Crystal Fibres (PCFs) are well known for allowing the implementation of specific waveguiding features that cannot be achieved with conventional optical fibres. This results from the design flexibility of the holey structure in the PCF cladding and/or core regions.

How optics and photonics is simply applied in agriculture?
SPIE Proceedings, 2013This paper highlights based on author's experience how optics and photonics is applied in Thai agriculture. These include spectral imaging based systems and mobile applications that have been implemented in the last 5 years for rice, fishery, and sericulture. Brief review of optics and photonics in agriculture will also be introduced.

Fiber-optical Photon Density Wave spectroscopy applied to highly concentrated biotechnical processes
Imaging and Applied Optics 2016, 2016Photon Density Wave (PDW) spectroscopy is a novel approach for monitoring biotechnical processes, by independently quantifying the absorption and reduced scattering coefficient of the biomaterial. Enzymatic milk coagulation, beer mashing and blood deoxygenation are discussed.
