Applications







Many applications can benefit from the high-density integration and custom design of the sensing elements and associated circuitry, as well as the on-chip analogue and digital processing that CMOS technology provides. CMOS image sensor technology is paving the way for a new generation of digital imaging and sensing products with broad applicability.

CMOS active pixel sensors exploit the vast resources of mature CMOS industry and can compete with charge coupled devices (CCD) for low power, high levels of integration and functionality. A fully compatible CMOS sensor technology enabling a higher level of integration of an image array with associated processing circuits is beneficial for many imaging applications such as, for example, scientific grade cameras, custom scanners, machine vision systems, medical imagers, microscope instrumentation, inspection systems and star trackers -among many others. A CMOS imaging system-on-chip requires lower voltages and dissipates less power than a CCD-based system with its supporting camera system.

The systems implemented in CMOS have a lower development cost when compared to other technologies and combine efficiently the sensor technology with the analogue/digital read-out electronics, the signal conditioning and the digital processing. For this reason, the range and the complexity of the applications are growing steadily and can be met by more and more aggressive scaling on the technology side and innovative solutions for the system development.

ISDI has experience in many areas of image detection, though we focus on medical, scientific and security-related applications. We possess unique radiation-hard technology that allows cameras to be installed in environments previously not thought possible.

ISDI has also experience in developing complete system solutions for various customer specific applications.

An example of a complete system solution for both x-ray crystallography and Transmission Electron Microscopy (TEM) developed by ISDI uses our DUOS sensor - two independent cameras in one array. TEM Detector was built for Pi-Phi project (http://eeepro.shef.ac.uk/piphi/index.html), and installed on one of the World's highest resolution microscopes - the Joel R005. Similar systems are used at the University of Oxford (http://www-em.materials.ox.ac.uk/) and for the German SALVE I-II project (http://www.salve-project.de). The x-ray version of the system has been installed on the Diamond Light Source - the UK's Synchrotron Facility (http://www.diamond.ac.uk).
