GigE Line Scan Camera

Basler Vision Technologies, Barrington, NJ, has introduced new features to its Basler Runner GigE Line Scan Camera, adding Shading Correction, Multiplier, and Divider features. The Shading Correction option can be used to compensate for non-homogenous lighting conditions and more accurately detect defects. The Divider functionality reduces the frequency of an incoming trigger signal, while the Multiplier increases the trigger signal frequency. To create the correct line acquisition rate for the camera, the input/output features offer transformations for trigger and encoder signals from a conveyer belt. Both features can be implemented by determining the correct parameters, which can be adjusted within a wide range. In order to accommodate the required line trigger frequency over the broadest variety of applications, the options can be used simultaneously.

Gigabit Ethernet Camera

DALSA Corp., Waterloo, ON, Canada, has introduced a GigE Vision®-compliant camera called the Genie HC Series. Typical applications include electronic manufacturing inspection, intelligent traffic systems (ITS), and food inspection. The series is comprised of three high-speed color camera models: Genie HC640 up to 300 fps in full resolution (640 × 480); Genie HC1024 up to 117 fps in full resolution (1024 × 768); and Genie HC1400 up to 75 fps in full resolution (1400 × 1024). Additional features include global electronic shutter with exposure control and on-board flat-field correction. The camera acts as a single machine vision component, integrating both the camera and board image acquisition in one package.

Micro-Optics

The Micro-optics business unit of Jenoptik Optical Systems, Huntsville AL, has expanded its single crystal Calcium Fluoride (CaF2) process capabilities for applications in the semiconductor market. The product range of CaF2 micro-optics include diffractive and refractive devices like Gaussian homogenizers, refractive fly’s-eye homogenizers, diffractive lenses, lens arrays for fill factor enhancement, as well as DOEs for mask inspection and illumination. The homogenizers and fly’s-eye lens arrays can be designed with rectangular apertures, reducing the number of required elements to homogenize an anamorphic or rectangular field. The products are provided using substrates from 75-150 mm diameter and thicknesses from 0.5-6 mm.

Remote-Head Camera System

Panasonic System Networks Company of America, Secaucus, NJ, has released the GP- KH232 single-chip HD Remote Head Camera System. The multi-format camera head, which measures 28 × 27 × 31.5 mm, is designed with a 1⁄3" CMOS sensor to deliver a native 1080p/60p resolution from HDMI output. The accompanying 120 × 36 × 157 mm camera control unit (CCU) and four-meter cable support digital transmission between the devices. The system is also designed with a flexible HD interface that includes RGB/YPbPr as well as the HDMI. The device delivers 900 TV lines of resolution with an S/N ratio of 54dB.

Multi-Sensor Camera

VRmagic, Cambridge, MA, offers a programmable multi-sensor camera that produces pixel-synchronous images from several positions. With a standard Debian Linux operating system, the camera provides developers with a platform for programming their own applications and transferring them to the camera by means of cross-compilers. Equipped with the DaVinci processor from Texas Instruments, the components feature a 300 MHz ARM9 processor running the Linux operating system, and a 600 MHz DSP with 4800 MIPs. The device has up to four external, 28 × 199 mm sensors that can be connected to the central unit of the camera by a flex-foil-cable with LVDS transmission. The cameras have 256 MB RAM and a 512 MB flash module, and the supported interfaces include Ethernet, USB 2.0 Host, RS-232 and general purpose I/O, analog video putput, and CAN Bus and PROFIBUS.

Scientific Cameras

Oriel®, a Newport Corporation Brand, Stratford, CT, has introduced two scientific cameras, the InstaSpec® ISX CCD and the InstaSpec ISX IR. The cameras are available with InstaSpec ProTM software, which provides system control of single- or dual-camera configurations, and all the functions of an Oriel spectrograph. The output from one or two cameras can be joined via a proprietary “stitch and glue” function to provide a single graphic display output of the acquired spectrum. The data format permits export to other packages for additional or enhanced post-processing tasks. The software features auto-calibration for the spectrograph and the installed cameras, and integrated pop-up help to facilitate setup.

CCD Cameras

IDS Imaging Development Systems, Woburn, MA, offers the UI-2280 (USB) and UI-6280 (GigE) series CCD cameras that feature the Sony sensor ICX-655 with a 5-megapixel resolution. The uEye models combine the performance of a global shutter sensor with a high image resolution. The 3.45-μm pixels of the CCD sensor ensure high light sensitivity. The USB version of the UI-2280 transfers 6.5 frames per second, and the UI-6280 models with GigE achieve 8.5 and 10 frames per second, respectively. In trigger mode, all cameras achieve the same speed as in freerun mode. Higher frame rates are possible when an AOI (Area of Interest) is set or binning (horizontal and vertical) is used. The 2⁄3" size makes the cameras suitable for microscopy applications. The cameras are available with housing options in color and monochrome versions. Several options for the filter glass in front of the sensor are available.

EMCCD Camera

Andor Technology, South Windsor, CT, has released the iXon X3 range of electron multiplying charge coupled device (EMCCD) cameras. The OptAcquireTM interface allows users to single-click various camera acquisition parameters. The device also offers Count Convert functionality, providing real time data acquisition in units of electrons or incident photons. Additional new features include spurious noise filters, a cropped sensor mode to boost frame rates, photo counting capabilities, and real-time data averaging.

Isolation of the Paenibacillus phoenicis, a Spore-Forming Bacterium

A microorganism was isolated from the surfaces of the cleanroom facility in which the Phoenix lander was assembled. The isolated bacterial strain was subjected to a comprehensive polyphasic analysis to characterize its taxonomic position. Both phenotypic and phylogenetic analyses clearly indicate that this isolate belongs to the genus Paenibacillus and represents a novel species.

Cell Radiation Experiment System

Cells can be irradiated under conditions that approximate those in living tissues.The cell radiation experiment system (CRES) is a perfused-cell culture apparatus, within which cells from humans or other animals can (1) be maintained in homeostasis while (2) being exposed to ionizing radiation during controlled intervals and (3) being monitored to determine the effects of radiation and the repair of radiation damage. The CRES can be used, for example, to determine effects of drug, radiation, and combined drug and radiation treatments on both normal and tumor cells. The CRES can also be used to analyze the effects of radiosensitive or radioprotectant drugs on cells subjected to radiation. The knowledge gained by use of the CRES is expected to contribute to the development of better cancer treatments and of better protection for astronauts, medical-equipment operators, and nuclear-power-plant workers, and others exposed frequently to ionizing radiation.
