aims: the synthetic colors are preferred by the food industry because of the variety of shades, intensity, uniformity, excellent solubility and stability. they are used in a variety of food products such as dairy products, beverages, baked products, confections and pet foods. food colors may have toxic effects on the human body. this study aimed to examine the amount of synthetic colors in some...

A new color coordinate system, which describes color by means of brightness, hue and saturation, is presented. The relative distance from the body diagonal to the nearest surface of the RGB color cube is used as the saturation. The conversions from and to the RGB space are described. Keywords—colour coordinate system, brightness, hue, saturation

Printed image multiplexing based on the design of metasurfaces has attracted much interest in past decade. Optical switching between different images displayed directly metasurface is performed by altering parameters incident light such as polarization, wavelength, or incidence angle. When using white light, only two-image implemented with polarization switching. Such are made nanostructures pe...

Introduction: The human skin is an active medium from the optical point of view. Therefore, the diagnostic and therapeutic techniques employing light are increasing. Current optical techniques are based on the measurement of the intensity of reflected absorbed or backscattered light from or within skin. Studies have shown that biological tissues, and in particular skin, demonstrate polarization...
