New self-induced Zernike filters (adaptive visualizing transparencies) based on the saturable absorption effect are suggested. The transparencies are thin layers made of translucent absorbing substance, and are placed in the focal plane of the receiving lens of a schlieren system. A possibility to create the transparencies having low response time (10−4 –10−5 s), which significantly reduces liability of the system to vibrations, is demonstrated. Obtainable images are equal to infinitefringe interference patterns allow getting a quantitative data. Examples of application of the organic dyes transparencies in aerophysic experiments are presented
