Method for fabricating an artificial compound eye

Dario Floreano, Jean-Christophe Zufferey

A method for fabricating an imaging system, the method comprising providing a flexible substrate (200), a first layer (220) comprising a plurality of microlenses (232) and a second layer (240) comprising a plurality of image sensors (242). The method furth ...

A Switched Capacitor Fully Differential Correlated Double Sampling Circuit for CMOS Image Sensors

Sandro Carrara, Yusuf Leblebici, Gözen Köklü

Complementary metal oxide semiconductor (CMOS) image sensors are more compatible than charge coupled devices (CCDs) for lab-on-a-chip platforms due to their inherited advantages. However, without the noise reduction circuits, CMOS technology wouldn’t be ab ...

The Gigavision Camera: A 2Mpixel Image Sensor with 0.56um2 1-T Digital Pixels

Edoardo Charbon, Hyungjune Yoon

We present a CMOS image sensor with deep-subwavelength, digital 1-T pixels designed for use in a digital film concept known as Gigavision (GV) camera. In GV, the levels of gray in the picture are derived from the concentration of activated pixels. Activate ...

2011

We propose a modification to the standard Bayer CFA and photodiode structure for CMOS image sensors, which we call 2PFC (Two Pixels, Full Color). The blue and red filters of the Bayer pattern are replaced by a magenta filter. Under each magenta filter are ...

Review of Light-weight Payloads for MAVs and Experiments with Thermopiles

Adrien Briod

This report investigates different payloads that could fit a small hovering indoor flying robot. First a review of useful equipment satisfying the strong weight constraint is realized, then work on a particular piece of equipment (thermal imaging sensors) ...

Ultrathin four-reflection imager

We present the design and experimental demonstration of an ultrathin four-reflection imager. The F/1.15 prototype imager achieves a focal length of 18.6 mm in a track length of just 5.5 mm, providing a 17° field of view over 1.92 megapixels of a color imag ...

Smart camera based on embedded HW/SW coprocessor

Marco Mattavelli, Romuald Mosqueron

This paper describes an image acquisition and a processing system based on a new coprocessor architecture designed for CMOS sensor imaging. The system exploits the full potential CMOS selective access imaging technology because the coprocessor unit is inte ...

Semiconductor Image Sensing

Peter Seitz, Nicolas Blanc

Silicon is an excellent detector material for electromagnetic radiation in the wavelength range of 0.1 to 1000 nm. In the visible spectral range (400-700 nm), external quantum efficiencies approaching 100% are obtained. When combined with the amazing minia ...

High-speed laser Doppler perfusion imaging using an integrating CMOS image sensor

Theo Lasser

This paper describes the design and the performance of a new high-speed laser Doppler imaging system for monitoring blood flow over an area of tissue. The new imager delivers high-resolution flow images (256 x 256 pixels) every 2 to 10 seconds, depending o ...
