MV-D1024E-3D01 camera for 3D profiling using laser triangulation available from Adept Electronic Solutions

MV-D1024E-3D01 camera for 3D profiling using laser triangulation

This enables the 3D profile of an object to be measured by the camera. Users do not need to process the image or perform any additional calculations on the computer leaving it free to do other tasks and therefore accelerating the process.

The MV-D1024E-3D01 uses a new algorithm which provides much higher accuracy than commonly used Centre of gravity (COG) techniques. The new algorithm is impartial to different surface textures and light conditions. Using the peak detector algorithm the camera can resolve up to 1/64th of a pixel.

Photonfocus use the new peak detector algorithm in combination of their patented LinLog technology which enables precise measurement in extremely varied light conditions. The LinLog technology prevents an overexposure (saturation) of the sensor while maintaining good grey scale information in darker areas.
 
In this way sub-pixel information in the image signal is maintained even under situations where for example there may be strong reflection from surfaces that are being examined. This offers significant advantages in all situations but especially when scanning metallic, translucent surfaces, organic fabrics or textiles.

LinLog stands for the Linear logarithmic characteristic curve of Photonfocus CMOS sensors. It offers a very high dynamic range of up to 120dB which is significantly higher than the 60dB of the best linear sensors. LinLog allows simultaneous acquisition of surface (2D – grey scale) and height (3D – Laser triangulation) inspection. The key surface is inspected in the linear region while the 3D triangulation is done in the logarithmic range.

The camera features a monochrome Photonfocus A1024B CMOS Sensor with 1024 x 1024 pixel resolution. The bit depth can be set to 8, 10 or 12 bit and a Camera Link interface allows for fast transfer of data. The MV-D1024E-3D01 is capable of up to 110 frames per second at full resolution.
 
In most cases however when profiling an object the aspect ratio of the image need not be one to one. Therefore the camera can be run at a lower aspect ratio with its ROI mode and so run at much higher frame rates. For example when run at 1024x128 pixels the camera can run at 980fps.

The MV-D1024E-3D01 is ideal for 3D applications such as 3D profiling for quality control, PCB inspection, food inspection, packaging inspection, and much more.

DALSA’s dual linescan CCD from Adept Electronic Solutions (22-Dec-2008)
DALSA’s novel dual linescan CCD breaks this trend. By doubling sensitivity with only a √2 increase in shot noise, the design delivers a greater signal to noise ratio, especially in light-starved situations. Functionally similar to TDI arrays, the design consists of two parallel arrays of photodiode pixels. Each pixel is connected to a selectable delay gate that either allows charges through or delays the charges by one scan line. Signal electrons from the two arrays (one of which has been delayed) are then combined on-chip into a single output (with no increase in amplifier noise). Because the delay is selectable, the sensor allows bidirectional scanning. The design also preserves conventional linescan features such as exposure control and high blue response. This dual linescan CCD is available from Adept Electronic Solutions.

New GigE cameras available from Adept Electronic Solutions (28-Nov-2008)
The GigE uEye SE (Standard Edition) series is available from Adept Electronic Solutions. The GigE uEye SE models are not only driver compatible with all cameras of the uEye range and across all interfaces, but also use the same SDK.

AVT long distance Firewire 1394a cables available from Adept Electronic Solutions (16-Oct-2008)
The FireWire standard specifies the maximum cable length for 1394a as 4.5m. However, 10m cables are also available. AVT introduce two longer FireWire cables, which can give a combined maximum length of 35 meters (114 feet) enabling the use of FireWire for applications that were previously unsuitable. These cables are available from Adept Electronic Solutions.
