ABSTRACTThe color of material can be determined by using the optical system which measures the intensity of reflected light and its incident beam, and based on CIE standard developed by Newton the Quantitative identification can be found. To carry out this measurement, an optical system was constructed using a polychromatic source light with a certain intensity, and then the light is projected to passed a surface of an object and its reflected light is were then detected using a silicon photodiode. Before started the experimental , the set - up was tested using a material standard which has been already known its numerical data (chromaticity coordinate, X, Y, 2). In this experiment were used the material standard with numerical data X = 80.56 ; Y = 85.39 ;and Z = 90.82, however by using this set-up measurement the shows that, the chromatic and X, Y, and Z are 80.57, 85.40 and 90.84, respectively. In this experiment a curve the curve showing relation between the percentage of optical reflectance and the wavelengths was presented. From the laboratory test we got that the experimental set up could be used for color identification purpose."

In this research a scattering technique employing f or war dscatter of a He-Ne C0,5328 pm, 30 mw) laser beam together with a 1024 x 1024 arrays CCD-V11 video camera as a detector was used for determining both particle size distribution and concentration. For determining the size distribution the "Differential Fourier Transform Technique" is chosen because it does not require matrix inversion or a priori knowledge of functional forms of size and it takes advantage of the Fast Fourier Transform.Measurements have been performed using this technique on cigarette smoke and smoke coming out, from burning clothes. From the experimental results it is shown that the diameter of cigarette smoke particles is between 0.3 and 1 . 3 pm. similar to that from a previous research C0.O4 - 1.00 pm). The measured size of smoke particles from burning clothes is 0.5 - 1.5 pm. similar to standard data Cabout 1 pm). But the obtained size distribution curves are still rough because of the limited observation scattering angle. It is also shown that the minimum and maximum concentration which can be detected are 1.8 x 107 particles/mma Cor 12.8 ppm) and 12.7 x 100 particles/=O Cor 906 ppm). This means that this technique can be used for measuring air pollutant concentration, as especially from smoke."

"This book covers all main aspects of guidance information processing technologies for airborne optical imaging seekers, including theoretical models; image pre-processing; automatic target detection, recognition and tracking; and embedded real-time processing systems. The book is divided into three major sections: firstly, a theoretical model for optical-seeker information processing is introduced; then information processing methods are presented, including target modeling, online image pre-processing, typical surface fixed-target detection and recognition, and moving-target detection and recognition; lastly, embedded real-time processing systems are introduced, including new system architectures, image processing ASIC/SoC design, embedded real-time operating systems, system implementation aspects, and system testing and evaluation technologies. The book offers a unique and valuable resource, helping readers understand both fundamental and advanced information processing technologies employed in airborne optical imaging seekers. "
