spectral identifi cation of hospital acquired infections demonstrated
Scientists at Applied Research Associates in the US have used intensifi ed CCD cameras to analyse Laser Induced Breakdown Spectroscopy (LIBS) data to differentiate between strains of a multiple-antibiotic-resistant species. Dr Rosalie Multari and her
colleagues believe that the ability to distinguish both species and strains using only raw spectra raises the prospect of rapid diagnostic instrumentation for use both within laboratories and in the fi eld. At a time of rising levels of MRSA and other hospital acquired infections, LIBS has been demonstrated to be a rapid and reliable technique for detection of
life-threatening bacterial pathogen species that can be found in medical environments.
Dr Multari’s team used the Andor
iStar intensifi ed CCD camera to analyse ten accumulated spectra from the laser-induced plasma plumes, with each spectrum accurately delayed by 1µs from the laser pulse and integrated on a 20µs temporal scale. The overall one-second detection period allowed the identifi cation of the fi ve bacterial samples with 100 per cent accuracy, including Escherichia coli, three methicillin-resistant Staphylococus aureus (MRSA) strains and an unrelated MRSA strain.
north American mV sales up in Q3 of 2010
Sales of machine vision components and systems in North America rose substantially in third quarter 2010, according to the Automated Imaging Association (AIA). Overall, year-over-year growth hit 68 per cent, up from second quarter 2010 at 60 per cent and fi rst quarter 2010 at 34 per cent. The Quarterly Machine Vision
Sales Tracking Report showed that sales were robust in all major machine vision supplier markets, including cameras, lighting, optics, imaging boards, software, application-specifi c machine vision systems and smart cameras. ‘These

results are very impressive, leaving little doubt that the recovery in the North American machine vision market is real and sustainable,’ noted Paul Kellett, AIA’s director of market analysis. ‘Based on industry expectations, we expect the recovery to continue at least another six months,’ he added. Applied Vision and Pleora
Technologies have both announced growth in earnings for 2010. Applied Vision exceeded its original 2010 forecast by 35 per cent, while Pleora fi nished its 10th year of operation in November with almost 40 per cent growth.

4k x 3CMOS Color Line Scan Camera
Experience a higher level of color line scan performance. The LT-400CL uses JAI’s advanced prism-block technology with 3 custom low-noise CMOS sensors to deliver 4096 pixels per line at a 16 KHz line rate. Hard dichroic filters and a single optical plane produce precise 24-bit or 30-bit color values for every pixel — without the color degradation, crosstalk, and halo ef fects found in tri - linear cameras. It ’s ideal for print inspection, food and beverage, or any other web application where color information is critical. See for yourself. Contact JAI today to discuss your requirements.
