CMOSIS CHR70M: Ultra-high-resolution CMOS Industrial Image Sensor
At Vision 2011, CMOSIS will introduce its new ultra-high-resolution image sensor CHR70M. The new CMOS sensor offers an image area of 10,000 by 7,096 active pinned photodiode pixels having a pixel pitch of 3.1µm x 3.1µm, in a 2-pixel sharing pattern. The sensor offers a frame rate of 3 fps at full resolution. Application areas include ultra-high-resolution industrial imaging, such as flat-panel and PCB inspection, document scanning and high-resolution areal photography. At Vision 2011, CMOSIS will exhibit in Booth D78, Hall 4 to demonstrate this new standard product.
The During the design of the sensor special precautions have been taken to assure that the two pixels with shared readout behave very similarly in terms of offset and gain, to avoid checkerboard-like artifacts and the need for off-chip calibration. This is particularly important for the B/W version since the effect, if present, would be masked by the bayer RGB CFA pattern in the CHR70M. Due to the staggered layout of the pixel readout circuitry all pixels show similar MTF behavior and angular sensitivity.
The sensor offers moving-window functionality. The windowing and other settings are programmable via the built-in SPI interface. All internal exposure and read-out timing values can be generated by a programmable on-board sequencer. External triggering and exposure programming is also possible.
The CMOSIS CHR70M works with 3.3V signaling levels. It is packaged in a 65-pin ceramic PGA.
The sensor will be available as a B/W with and without micro lenses, as well as a bayer RGB color version with microlenses.. All versions will be offered with glass cover with two-sided anti-reflective coating (ARC)
Monochrome and RGB color CHR70M samples with micro lenses will be available form January 2012. An evaluation kit is available for rent or purchase.
Since the CHR70M started its life as a custom imager for biometric applications, the sale of this imager for these kind applications is excluded.
