ESPROS Announces BSI ToF Imager

ESPROS announces epc660, a BSI 3D-TOF imager with a resolution of 320 x 240 pixels. epc660 is an integrated SoC combining high-QE BSI CCD pixel array and complete control logic to operate the device, an integrated LED driver, capable of driving more than 200mA peak current, and a high-speed 12-bit parallel video interface. The sensor speed is 66 TOF frames per second at QVGA resolution or up to 1000fps in "advanced operation modes." The advanced CCD pixel architecture is said to be the enabler for camera systems that can tolerate ambient light levels of up to 130Klux. Depending on the system design, a resolution in the millimeter range for distances up to 100 meters is said to be possible.

The epc660 features various modulation schemes on-chip, such as frequency hopping, random modulation, and CSMA/CD. There is also a dedicated modulation input that can be externally fed with any desired modulation signal.

World's Smallest Thermal Camera

Norvegian-language TU Industry reports that Prox Dynamics' PD-100 world's smallest military grade UAV is equipped by the smallest to-date FLIR thermal camera weighting just 0.5 gram. A few months ago was their smallest camera 25 grams. The unit which is mounted in the PD 100 T weighs half a gram, says CTO and Prox Dynamics Entrepreneur Petter Muren. The whole drone with visible and thermal cameras weighs just 17.5g:

Eric Fossum Life Story

Trinidad Guardian publishes an article based on Eric Fossum's lecture on image sensors at the local university. After going through many interesting facts from the image sensor history, the article quotes Eric:

"Looking back at his work with the CMOS sensor, he boiled his learnings down into five brief sentences:

•Create the invention.
•Successfully commercialise it.
•Deliver on the promise compellingly.
•Sell the company.
•Defend the patents.
