Frame Grabbers

AVC-2 frame grabbers from VRmagic (Mannheim, Germany) transmit converted digital signals in real time via composite, Y/C, or Svideo, in monochrome or color mode. The VRmAVC-2 is supplied with power via its USB connection and is available as an OEM model and model with housing. The integrated 64 MB memory ensures a stable operation. The VRmD3AVC-2 and VRm- DAVC-2, based on the intelligent camera platforms, perform image processing tasks fully autonomously. The D3 frame grabber VRmD3AVC-2 features a dual-core chip with floating point unit (FPU) running Ubuntu Linux. Peripherals, including a monitor via HDMI, can be connected directly; equipment can be controlled via RS232 or GPIOs. For Free Info Visit: http://info.hotims.com/55596-153

CMOS Cameras

SMARTEK Vision (Cakovec, Croatia/New London, CT) has added GCP2061 and GCP2046 models to its Giganetix Plus camera series. The new industrial cameras are equipped with the Sony Pregius Exmor IMX250 and IMX252 sensors. With a high dynamic range of 70.9 dB and a readnoise value of 2.3 e-, the models support outdoor and traffic-monitoring applications. The cameras have a resolution of 3.2 or 5.1 megapixels at a pixel size of 3.45 μm. A variable-speed shutter function, a variety of exposure methods, a maximum of 64 definable regions of interest, and external trigger modes all enable application control and image transmission. Additional features of the Giganetix Plus series include fully GigE Vision-compliant hardware and driver interfaces, Windows- and Linux-compatible Giganetix GigE Vision SDK, and the use of industrial connectivity standards.

The Need for Speed

With today’s engineering challenges, the need for non-contact, high speed thermal measurement has never been greater. Traditional forms of temperature measurement such as thermocouples and spot pyrometers do not offer the resolution or speed required to fully characterize high speed thermal devices and provide adequate temperature measurement. Infrared cameras offer thousands, even millions, of points of non-contact high speed thermal measurement. However, not all infrared detectors are created equal. Here we’ll discuss the most common types of thermal infrared detectors and the capabilities as well as limitations of each. You’ll find this discussion helpful for solving applications involving fast moving targets or targets with fast thermal slew rates and the following information will provide the knowledge base to ensure measurements are reliable, avoiding a “garbage in, garbage out” situation.

The Advantages of Cooled IR Cameras

For many years, thermal imaging cameras have been used by scientists, researchers and R&D specialists for a wide range of applications, including industrial R&D, academics & research, non-destructive testing (NDT) & materials testing, and defense and aerospace. However, not all thermal cameras are created equal and for some applications dedicated, advanced thermal cameras with high speed stop motion capability are required in order to get accurate measurements.

Area-Scan Camera

The SAPPHIRE S-25A70/CXP area-scan camera from Adimec (Eindhoven, the Netherlands/Stoneham, MA) is equipped with the CoaXPress V1.1 Quad interface (4 x CXP-6). CoaXPress CXP-6 Quad offers a peak transfer rate of 2 Gigapixels/s. Data transmission between the camera and frame grabber occurs at up to 25 Gbits/s (4 x 6.25 Gbits/s). The S-25A70/CXP camera utilizes the ON Semiconductor Vita25k global shutter image sensor. Additionally, the 25-Megapixel CMOS global shutter device delivers images of 5120 x 5120 pixels at a maximum of 73 full frames per second (fps). A defect pixel correction algorithm maintains image uniformity. At maximum speed, cable lengths over 30 meters are supported without the need for signal repeaters.
