Abstract :
The interest in dynamically tuning lens has attracted great attention to fabricate compact vision systems. Here, we discuss the fabrication and characterization of a simple, tunable, yet fully disposable, except imaging sensor, microfluidic-based optical device. The desired compact system is structured on a PDMS microfluidic. Tunable lens actuated by flow pressure (2 mm in diameter) is controlled by a syringe pump. The contrast value is provided by introduction of Melanin cover between image sensor, lens and PDMS chip. With the advantage of automatic focal change, an inaccurate detection of an object is eliminated by shifting focal plane.
