Monsters in cyberspace cyberphobia and cultural panic in the information age

This paper explores popular attitudes toward the Internet (and computer-mediated communication more generally) by mapping some of the more threatening, transgressive and 'monstrous' images associated with cyberspace. An account of risk consciousness is developed in three parts: (1) comparisons with earlier information technologies reveals similarities and differences with regard to public attitudes toward cyberspace and its risks; (2) the development of a model of contemporary teratological space derived from images of boundary-dissolving threats, intrusive alterities and existential ambivalences created by the erosion of binary distinctions and hierarchies; and (3) possible historical and sociological explanations of cyberpanic drawing on recent theorizations of globalization (capitalism/information society theory, risk society theory, reflexive modernization theory, and alterity theory).     

When images matter: Internet child pornography, forms of observation and an ethics of the virtual

The arrest of Pete Townshend, lead guitarist for The Who, for downloading and possessing Internet child pornography and the publicity surrounding the case provides an initial point of discussion concerning the emergence of an ethics of the image that is not predicated on the actual evidential status of that image but on more virtual forms of observation. The discussion in this article focuses on three substantive aspects of this event - legislation in the UK and the US, expert psychological discourse, and public discussion in the UK press - in order to present a particular and situated rendering of forms of virtual observation. The context to this discussion concerns the notion that digital imaging technology presages a need for new legislation, law enforcement and social analytical frameworks for understanding and tackling the production, distribution and consumption of images of child sexual abuse.     

The digital divide in Sydney

In Australia, there has been limited research into the issue of the digital divide. Even less attention has been given to the social and spatial characteristics of this phenomenon, particularly within metropolitan areas. This paper attempts to fill this gap by examining the social and spatial characteristics of computer and Internet use in Sydney. The findings suggest that those individuals who are socially and economically disadvantaged have lower rates of computer and Internet use, and that these individuals also risk exacerbating their disadvantage status if these demand-side barriers are not addressed. If we are to address disparities in computer and Internet use in Australia we need to consider more fully the social and spatial nature of such disparities that prevent individuals from accessing such technologies in an increasingly 'wired' world.     

基于数码相机图像的三维重构

非定值相移量的单步相移同轴数字全息

提出一种非定值相移量的单步相移同轴数字全息算法。对CCD面上的干涉光强进行了分析,用图像相减法算出CCD面上不能确定相位正负的物光波,再记录一帧有相移的干涉光强,来确定相位的正负。其特点是有相移的这一帧干涉光强没有参与物光场大小的运算,只是用于相位符号的判断。该算法对相移误差不敏感。
