Abstract: Disclosed is a method of preparing a tin oxide nanoribbon acetone gas sensor. The detailed steps are: placing tin oxide powder and silicon sheet into a horizontal tube furnace; pretreating gas inside the tube furnace; firing ultra-thin tin oxide nanoribbons at high temperature; dispersing ultra-thin tin oxide nanoribbons; preparing ultra-thin tin oxide nanoribbon acetone gas sensors. The tin oxide nanoribbons obtained by this preparation method are extremely thin, and the nanoribbons are flexible. The tin oxide nanoribbons deposited on the silicon sheet are easy to disperse, which brings greater convenience to the practical application of tin oxide nanoribbons. The tin oxide nanoribbons obtained according to this method of preparing ultra-thin tin oxide nanoribbons are sensitive to acetone gas, and therefore can be applied into an acetone gas sensor.

Abstract: The embodiments of the present disclosure provide a ranging system of a dual optical frequency comb time-of-flight manner based on dispersive Fourier transform. The embodiment of the present disclosure introduces a dispersive Fourier transform technology into a conventional dual optical frequency comb system, which amplifies a stray relationship of a pulse time domain using a dispersion element and obtains a precise position relationship of three pulses directly through interfering fringe information. Therefore, the “dead zone” in the conventional dual optical frequency comb ranging system is eliminated, and the ranging accuracy of the system is greatly improved, and a repetition frequency difference of the dual optical frequency combs can be increased to a magnitude of MHz, which greatly improves the ranging speed. The ranging system has advantages of a large measurement range, a high measurement accuracy, and a high measurement speed.
