2. Current Image Sensing Technology: CCD and CMOS ~ 30 Mega Pix (best of breed)New Image Sensing Technology: Quantum tunneling photodetector arrays (QIST*) ~ 300 TERA Pix at 12 wafer level *Quantum Image Sensing Technology10,000 X better 3. Are CCD and CMOS devicesthe last word in Image Sensing?Disrupting the current market ... 4. Status QuoExisting CMOS and CCDs are reaching their technical limitations based oncurrent physics - there are problems with heat, leakage and diffraction,complex manufacturing, limits of minaturisation of pixels, etcNew Image Sensor OpportunityQuantum tunneling photodetector array technology offers possibility to createimage sensors; with none of the above limitations, with up to 100 TERA Pixelsper individual image sensor, extremely fast, operating under very low power,from UV to visible to IR spectrum, and resolving colour spectrum.Creating vast new opportunities 5. Hausken, T. 2009.

Quantum Tunneling Photodetector Arrays can offer2,500 X greater pixel density than CCD and CMOS Image Sensorsoffering up to100 TERA Pixels per individual image sensorBreaking the limits of old technology 7. Quantum Tunneling Photodetector Arrays offer Much faster response time even in 1,000s of frames per second Easier ne color gradation such as 16-bit per componentcolour, or multiple colour RGBYCMK sensors Easy adjustment of spectrum coverage from infrared to X-rayGreat new advantages 8. Quantum Tunneling Photodetector Arrayswill be particularly useful in: affordable super hi-res earth, marine and space surveillance new generation cameras and vision equipment ultra compact solutions for eye replacement in the visuallyimpaired wide use in both civilian and classied devicesWide applications 9.
