Abstract [en]

Schlieren photography is a technique used to visualize variations in index of refractive in gaseous media. To compare different configurations of Schlieren photography, four kinds of Schlieren setups were constructed in this experiment. As the basis of comparison, their sensitivities were measured and Schlieren images were obtained which were used as a tool to study the temperature gradient of the burning candle. It was found that the Single mirror system had the highest sensitivity but the Schlieren images obtained by Z-type system showed the best quality measuring to visualize temperature gradient. Limited by the requirement of large size and good quality convex lens, the Single-field-lens system and the Dual-field-lens system did not perform equally well.
