Résumé :

A near-infrared spectrometer incorporating solid-state design applicable for industrial quantitative/qualitative process monitoring analysis is presented. The solid-state near-infrared spectrometer provides inherent wavelength stability necessary for long term calibration accuracy. The spectrometer consists of a 24 volt, 10 watt quartz-halogen-tungsten regulated source with optical feedback. Wavelength dispersion was accomplished using a 50 μm entrance slit, f/4, 0.25 meter spectrograph equipped with astigmatism correcting toroidal mirrors and a 300 gr/mm plane reflectance ruled grating blazed

Résumé :

Egg is a fragile component within the human diet. Important changes occur in egg during storage. Prediction of these changes is critical in order to grade the eggs upon their quality and freshness. The objectives of this study were to evaluate the application of visible and near infrared spectroscopy as a non-destructive method for the assessment of egg quality and freshness. Therefore, visible and near infrared transmittance spectral data ranging from 350 to 2500 nm was collected with the help of a radio

The purpose of this research is to ascertain potential iris scan data variations from near infrared waves derived from fluorescent illumination. Prior studies of iris data variances from infrared wave interference of halogen, incandescent, and sunlight with iris cameras suggest that similar changes may exist under near infrared wavelengths from fluorescent light. The concern is that the fluorescent energy emission may interfere with the near infrared detection of an iris camera. An iris camera is used to measure human eye characteristics known as biometrics. If such infrared emission is statis

Silicon based sensors is a commonly used technology in digital cameras today. That has made such cameras relatively cheap and widely used. Unfortunately they are constructed to capture and represent image quality for humans. Several image applications work better without the restrictions of the visible spectrum. Human visual restrictions are often indirectly put on technology by using images showing only visible light. Thinking outside the box in this case is seeing beyond the visible spectrum.

碩士<br>國立臺灣大學<br>生物產業機電工程學研究所<br>89<br>This study focuses on using near infrared (NIR) technology to investigate the sugar content and acidity in grape and mango using pre- and post-dispersive spectrophotometers. The calibration models of sugar content and acidity are developed and applied to design an on-line NIR inspection system. The spectra of juices and intact fruits were scanned and analyzed, and then the results points out that all the best analyzed model were modify partial least square regression (MPLSR) instead of the best grape juice transmittance spectra absorption of sugar content

The effects of preparation conditions on the particle size, structure, and optical and NIR photothermal conversion properties were investigated. Two systems were studied, including LaB6 and Cs0.33WO3 nanoparticles. LaB6 nanoparticles have been prepared successfully by a stirred bead milling process. The anionic surfactantdodecylbenzenesulfonic acid was found to be suitable for the grinding and dispersion of

Résumé :

yes<br>A transflectance near infra red (NIR) spectroscopy approach has been used to simultaneously measure drug and plasticiser content of polymer melts with varying opacity during hot melt extrusion. A high temperature reflectance NIR probe was mounted in the extruder die directly opposed to a highly reflective surface. Carbamazepine (CBZ) was used as a model drug, with polyvinyl pyrollidone-vinyl acetate co-polymer (PVP-VA) as a matrix and polyethylene glycol (PEG) as a plasticiser. The opacity of the molten extrudate varied from transparent at low CBZ loading to opaque at high CBZ loading.

碩士<br>國立臺灣海洋大學<br>食品科學系<br>93<br>Abstract The purpose of this research is to describe the probability of using near infrared spectroscopy to analyze histamine spectrogram of the unit of the fish meal. 176 samples were collected and analyzed. The value through HPLC for the analysis of benzoylated amines is 10.6-109.6 ppm. There were 125 samles under 100 ppm, 44 samples between 100-500 ppm, and 7 samples beyond 500 ppm. WinISI Ⅱwas used to analyze the correlation between histamine contents and absorption spectrums of fish meal measured by near infrared spectroscopy. The 2nd derivative treatment

To increase the production capacity and reduce the cost of production of cell-phone camera, we develop a new adjustable focus system with this new technique. This method can test the resolution of cell-phone camera reaching 1.3 million pixels.

Résumé :

碩士<br>國立中興大學<br>生物產業機電工程學系所<br>96<br>In this study, the near infrared spectroscopy (NIRS, Kubota K-BA100) was used to determinate the reflective spectra of the banana, in the wavelength range from 500nm to 1010nm, and to analyze and compare it with the actual sugar content of the cut banana. By applying multiple linear regression (MLR) analysis, the correlation of sugar content and second derivative spectra could be obtained. From the results of analysis, the total calibration equation is better acquired when it consists of 6 wavelengths (i.e. 924nm, 782nm, 874nm, 814nm, 882nm and864nm). The c
