摘要
激光在空气中被声悬浮扁水滴散射时的广义彩虹散度[Marston and Trinh， Nature 312, 529-531(1984)]显示了光场与波前形状之间的关系。散射光波前的形状取决于悬浮体控制的水滴形状。目前的研究表明，另一种基于阵列的超声波悬浮器设计被称为“TinyLev”，可以用来捕捉水滴，以记录广义彩虹。双曲脐局灶切片。TinyLev与基于ccd的成像相结合，可能使广义彩虹的调查更容易实现。
Generalized rainbows of oblate water drops in air recorded using a TinyLev ultrasonic levitator.
The generalized rainbow caustics in the scattering of laser light by acoustically levitated oblate water drops in air [Marston and Trinh, Nature 312, 529-531 (1984)] display relationships between optical wavefields and the shape of wavefronts. The shape of the scattered optical wavefront depends on the drop shape controlled by the levitator. The present investigation demonstrates that an alternative array-based ultrasonic levitator design known as "TinyLev" can be used to trap drops for the purpose of recording generalized rainbows. The hyperbolic umbilic focal section was viewed. The TinyLev combined with CCD-based imaging may make investigations of generalized rainbows more accessible.
