Methods and Means of Operational Control of Narrow-band Optical Radiation Spectrum Parameters 000_14.pdf

A brief analysis of the well-known means of operational control parameters of optical radiation spectrum as well as the application of these means has been submitted. It is shown that the main trend of development of spectral analysis means is to improve their performance. A method for measuring the parameters of a narrow-band spectrum of optical radiation in two photodetectors with predetermined spectral characteristics described by a Gaussian function with different wavelengths at the maximum bandwidth has been described. The possibility of operational determination of both the central wavelength of the emission spectrum and the spectral width with the use of the proposed method has been shown. The proposed method can improve performance of monitoring and control sources of optical radiation. The functional scheme and the main characteristics of the experimental prototype device based on the proposed method have been shown. It is experimentally demonstrated that the possibility of application of the developed embodiment of the device for determining the thermal properties of LEDs based on the emission spectrum shift as a result of self-heating of the LED operating current. The results of the testing methodology for measuring thermal properties of LEDs with the use of several samples of serial devices have been obtained.
