| Abstract: | To measure temperature field with acoustic pyrometry , a kind of measurement system of acoustic waves flight time based on cross-correlation method is developed. The principle of acoustic pyrometry is explained and the design and realization of this system is presented in details in the paper. This system can measure the flight time accurately. The experiment result indicates that the system is stable and can satisfy the requirement of acoustic wave flight time measurement . A brief chart of system design and measuring instrument are given out. |
