Development and prospect of varifocal-liquid technique

This paper introduces a new zoom lens technique that is varifocal-liquid technique. First of all, it reviews and summarizes the domestic and foreign scientific achievements on the varifocal-liquid techniques, and gives the basic principle, realization forms and the classification of liquid lenses. Then, the paper evalu- ates the excellent performance of the liquid lenses and their influences on optical fields, especially the revolu- tionary change brought by varifocal-liquid technique. Finally, for the development status and application engi- neering situation, it analyzes the urgency problems unsolved in varifocal-liquid technique. Finally, and it points out that the investigation and development of varifocal-liquid techniques should focus on the mechanism research to eliminate the effects of temperature field and gravity field on the performance of liquid lenses, the design of off-axis system and asymmetric system and further promoting the practical applications of the liquid lenses.
