Adaptive liquid lens actuated by photo-polymer.
An adaptive liquid lens actuated by a photo-polymer is demonstrated. The lens cell consists of a top glass substrate and a bottom plastic slab with two holes: reservoir hole and lens hole, which are sealed with elastic membranes. A photo-sensitive polymer is attached to the membrane of the reservoir hole. Under blue light irradiation, the polymer is bent which exerts a pressure to regulate the ...
متن کاملMicro-patterned photo-aligned ferroelectric liquid crystal Fresnel zone lens.
In this Letter, we disclose a fast switchable Fresnel zone lens (FZL) by confining the ferroelectric liquid crystals (FLCs) in multiple microscopically defined photo-aligned alignment domains. The photo-alignment (PA) offers good control on the anchoring energy (W) by mean of irradiation doses (ID) and thus excellent alignment for FLCs. Two operational modes of the FLCFZL, i.e., FOCUS/OFF and F...
متن کاملTele-Insuring: New Possibilities for Customer-Orientation
AS STRATEGIC IMPERATIVE Clearly, one of the most important strategic imperatives for companies in the financial service sector in general, and especially in the insurance industry is customer-orientation, in particular due to current structural changes in the insurance industry (see empirica 1995; Prokop 1996): + The high intensity of the (Europe-wide) competition, measures of deregulation, and...
متن کاملNew Concepts in Tele-Autonomous Systems
We have taken up the challenge of integrating telemanipulation technology and autonomous system technology. We are seeking methods for integration at a fundamental rather than an ad-hoc level. We believe that success in this effort can open up new space and defense applications now beyond reach of either technology alone. In our presentation at this symposium, we introduce a series of concepts ...
متن کاملA new robot architecture for tele-echography
This paper presents a slave robot carrying an ultrasound probe for remote echographic examination. This robot is integrated in a master-slave system called robotic tele-echography (TER). The system allows an expert operator to perform a remote diagnosis from echographic data he acquires on a patient located in a distant place. The originality of this robot lies in its architecture: the cable-dr...
