Multifocal laser direct writing through spatial light modulation guided by scalable vector graphics
Multifocal laser direct writing (LDW) based on phase-only spatial light
modulator (SLM) can realize flexible and parallel nanofabrication with high
throughput potential. In this investigation, a novel approach of combining
two-photon absorption, SLM and vector path guided by scalable vector graphics
(SVG) has been developed and tested preliminarily, for fast, flexible and
parallel nanofabrication. Three laser focuses are independently controlled with
different paths, which are according to SVG, to optimize fabrication and
promote time efficiency. The minimum structure width can be as low as 74 nm.
Accompanied with a translation stage, a carp structure of 18.16 m by 24.35
m has been fabricated. This method shows the possibility of developing LDW
techniques towards full-electrical system, and provides a potential way to
efficiently engrave complex structures on nanoscales
Semantic multimedia remote display for mobile thin clients
Current remote display technologies for mobile thin clients convert practically all types of graphical content into sequences of images rendered by the client. Consequently, important information concerning the content semantics is lost. The present paper goes beyond this bottleneck by developing a semantic multimedia remote display. The principle consists of representing the graphical content as a real-time interactive multimedia scene graph. The underlying architecture features novel components for scene-graph creation and management, as well as for user interactivity handling. The experimental setup considers the Linux X windows system and BiFS/LASeR multimedia scene technologies on the server and client sides, respectively. The implemented solution was benchmarked against currently deployed solutions (VNC and Microsoft-RDP), by considering text editing and WWW browsing applications. The quantitative assessments demonstrate: (1) visual quality expressed by seven objective metrics, e.g., PSNR values between 30 and 42 dB or SSIM values larger than 0.9999; (2) downlink bandwidth gain factors ranging from 2 to 60; (3) real-time user event management expressed by network round-trip time reduction by factors of 4-6 and by uplink bandwidth gain factors from 3 to 10; (4) feasible CPU activity, larger than in the RDP case but reduced by a factor of 1.5 with respect to the VNC-HEXTILE
