WidePIX 2(1)×15 – MPX3
The Advacam’s WidePIX 2×15 – MPX3 with resolution of 512 (256) x 3840 pixels i.e. 1.97 (0.98) Mpixels is composed of Medipix3 hybrid detector electronics tiles. It has a built-in Time-Delayed-Integration (TDI) which proves to be very useful for scanning in industrial applications. It is very advantageous for continuous scanning. WidePIX 2(1)X15 – MPX3 is available with Si or CdTe sensors for analysis of the soft and hard X-ray spectrums, respectively.
The minimum detectable energy is typically 3 keV for Si and 5 keV in case of CdTe sensor. The intrinsic spatial resolution of the camera is defined by pixel size which is 55 µm for WidePIX 2×15 – MPX3. The pixels situated on the border of tiles are 2 times bigger in one direction, while the corner pixels of tiles are 2 times larger in both directions.
The particle counting principle eliminates any additional noise generated by the sensor or electronic readout. It allows 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.Both devices are suitable for CT scanners, which can take advantage of large sensitive area without any gaps. The camera 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 be then 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 quality of spectra measured in individual pixels.
The camera is connected to a computer via USB 2.0 cable. The readout time is 50(25) ms per frame resulting in maximum frame rate of 20 (50) frames per second.
