Large numbers of these high power lasers have found their way into people's lives and are being used by people who may be unaware of potential eye injury, resulting in increased reports of retinal injuries. Therefore, many countries have issued restrictions or regulations, on the power limit of laser pointers used for demonstration purposes. At present, there are none of these regulations on the sale and use of laser pointers in Thailand. In this research, an accurate, inexpensive, user friendly, laser pointer power testing kit will be built for the measurement of optical power emitted from handheld lasers. The setup consists of a thermopile power meter, optical bandpass filters, lens mounts, lens tube, and iris. Output power of about 20 laser pointers randomly purchased from various sources will be determined, including evaluation of measurement uncertainty. The safety level with respect to the limits imposed by the US Code of Federal regulations will be also discussed.","PeriodicalId":222009,"journal":{"name":"2016 4th International Conference on Photonics, Optics and Laser Technology (PHOTOPTICS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128162009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The operation of OFETs depends on the charge accumulation at the interface between an organic semiconductor and a dielectric material, induced by the voltage applied at the gate electrode. Direct measurements of the electric-field distribution in an operating device are useful for proposing and validating theoretical models for OFET operation. Here we propose using the second-order nonlinear optical process of Sum-Frequency Generation vibrational spectroscopy (SFG spectroscopy) to probe the presence of an electric-field in the dielectric layer of OFETs, in a non-invasive, non-destructive and remote fashion. The OFETs were fabricated with a dielectric layer consisting of poly(methyl-methacrylate) — PMMA, and an active layer based on poly(3-hexyl thiophene) — P3HT, and SFG spectra were acquired from the channel region of operating OFETs. It was observed the appearance of vibrational bands due to carbonyl groups (∼ 1720 cm−1) of the PMMA layer, whose χ(2) were induced by the electric-field within the dielectric, similarly to a reversible poling of polymers. This phenomenon opens up the possibility of mapping the spatial charge distribution in the conducting channel using SFG microscopy in operating devices.","PeriodicalId":222009,"journal":{"name":"2016 4th International Conference on Photonics, Optics and Laser Technology (PHOTOPTICS)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122740948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The traditional PDT treatments applied with external light sources deliver a non-uniform light distribution on the skin surface due to the anatomical particularity of the human body (head vertex, hand, etc.). Therefore a successful PDT obligates a homogenous and reproducible light delivery. With this purpose, plastic optical fibres (POF) have been woven in textile in order to create macro-bendings and thus emit out the injected light directly to the skin. To improve the light intensity and light emitting homogeneity of the LEF, Doehlert Experimental Design is applied. Fifteen experiments performed to analyze the response surface. Light properties of the prototypes were evaluated. The proposed models fitted well with the experimental data and enabled the optimal set up the warp yarns tensions. This study showed that RSM was a suitable tool to optimize the models of light diffusion properties.","PeriodicalId":222009,"journal":{"name":"2016 4th International Conference on Photonics, Optics and Laser Technology (PHOTOPTICS)","volume":"232 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132038709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
