A multi-chip industrial scanner and imaging detector with the ability to provide spectral material-sensitive “color radiography“. It suits CT scanners and supports a hardware-based Time-Delayed-Integration (TDI) mode. The camera resolution is 512 (256) x 1280 pixels, comprising a Medipix3 hybrid detector with a silicon or CdTe sensor.
Industrial spectral scanner camera with a large area imaging detector
The large area imaging detector WidePIX L2(1)x5 – MPX3 with a resolution of 512 (256) x 1280 pixels is composed of Medipix3 hybrid detector electronics tiles. Each tile (256 x 256 pixels) is attached to a silicon or CdTe sensor. Therefore, the whole area of the WIDEPIX L2(1)x5 – MPX3 device is fully sensitive, and there are no gaps between sensor tiles. Each pixel has two integrated 12-bit digital counters and two energy discrimination thresholds. The counters store number of registered particles, e.g., X-ray photons, with energy above the appropriate threshold. Both counters can be joined to a single 24-bit counter, providing an enhanced dynamic range.
The particle counting principle eliminates any additional noise generated by the sensor or electronic readout. It allows for acquiring X-ray images with very high contrast and wide dynamic range. Therefore, even low-contrast structures such as plastic or soft tissue are easily detectable in X-ray images.
The camera is suitable for CT scanners, which can take advantage of large sensitive areas without any gaps. The WIDEPIX L1x5 – MPX3 variant moreover supports a hardware-based Time-Delayed-Integration mode for online (continuous) scanning applications.
The energy discrimination thresholds of Medipix3 technology allow spectral X-ray imaging. Different materials in an inspected sample could then be identified based on their spectral X-ray attenuation properties. Energy spectra could be measured typically from 5 keV upwards.
The Charge Summing Mode implemented in the pixel electronics provides hardware-based correction of signal cross-talk between pixels. This further considerably improves the detector spectral response and, therefore, also the quality of spectra measured in individual pixels.
The camera is connected to a computer via an ethernet cable.

Imaging Application
NON DESTRUCTIVE TESTING
Experience the power of our advanced cameras, delivering unmatched sensitivity, spatial resolution, and contrast. Our single-photon counting Cameras quickly uncover hidden details in various materials, from light composites to thick welded parts. The technology suppresses scattered radiation, capturing quality images in record time. The capabilities of our photon-counting X-ray imaging unveil internal material structures and spot defects like porosity, fiber orientation, micro-cracks, and delaminations with unparalleled precision. Elevate your NDT with our industry-leading solutions, setting new standards in defect detection.
MATERIAL ANALYSIS
Do you need to determine the material composition of your sample? Minerals, alloys, polymers, electronics, batteries, or pigments? Our cameras are based on cutting-edge single X-ray photon counting sensors, and each detected photon is processed individually. This approach also allows measuring the wavelength of photons. It brings unprecedented image quality and new possibilities, such as material-sensitive X-ray imaging. Moreover, our detectors enable fast and compact X-Ray Diffraction (XRD) and Crystallography solutions. XRD sample analysis is performed up to an order of magnitude faster than conventional systems. Spectral sensitivity provides a unique ability to inspect the sample surface and its interior (Energy dispersive XRD).
BIOMEDICAL
Cancer research, bio-mechanics, and drug testing are just a few examples of X-ray imaging contributing to biology and medicine research. New photon-counting detectors represent a severe advancement to these applications compared to previously used methods. The energy sensitivity of modern cameras opens better possibilities for identifying individual types of tissue and contrast agents. That has significant consequences in various industries, for example, cancer research, where the tumor tissue can be better distinguished from the healthy one.
