A telescope support stand system for side cutaway view of the present invention in the contracted position. The method including following steps: Step 1, industrial acetic acid is fast distilled; Step 2, filtering the fraction by membrane of 0. The correlation value undergoes operation of a correlation non-linear processor to obtain a value. An optical transmission line of the above-mentioned system is normally regulated beforehand so that the wavelength characteristic of the following signal lights is flat when light at the total level of thirty-two signal lights in a predetermined range of wavelengths is transmitted.
