Spectrometers measure optical power as a function of wavelength. Optical spectrum analysis is very important part of optical spectroscopy applications. The work documented in this paper gives a working knowledge of converting spectrographs to spectrograms using color space transformation techniques. In this work it is demonstrated that how a webcam spectrometer can be used to measure spectral composition...
Spectrometers measure optical power as a function of wavelength. Optical spectrum analysis is very important part of optical spectroscopy applications. A low cost DIY spectrometer can be created using DVD-R as diffraction grating and camera as the sensor. Pre-calibration of the DIY spectrometer using a mercury vapor based reference light source is essential. The work discussed in this paper is a proposed...
The work documented in this paper gives a working knowledge of mapping the spectral lines in the emission spectra of physical objects to their corresponding wavelengths. In simpler terms RGB triplets in the spectrogram image are mapped to their corresponding wavelengths on the visible spectrum. Peaks of CIE RGB color matching functions are directly mapped one on one to peaks of the R, G and B intensity...
This paper presents simulation study on power management topology for a LED based lighting panel to be used in studios, working on the concept of additive color mixing employing high brightness LEDs of one watt each and having four different circuits for the four constituent colors The constituent colors are the three primary colors, red, blue and green with amber added to obtain better color rendering...
