 C650 based Hyper Spectral Camera is flown in Chandrayaan-1 for chemical mapping of lunar surface in visible and near infrared spectral regions. On chip high speed timing, precision analog processing, row wise programmable gain and 12-bit ADC makes the sensor a system on chip. Please visit http://www.isro.org/Chandrayaan/images/3HysI_Roll.jpg  for 64 band imagery of Moretus crater on polar region of moon surface.

 C640 based Terrain Mapping Camera on-board Chandrayaan-1 takes high resolution imagery of polar region of lunar surface. Very high dynamic range of the sensor helps in taking excellent features of dark polar sections of moon surface. This camera is planned to make three dimensional atlas of moon surface over its mission life. Please visit http://www.isro.org/pslv-c11/videos/tmca.htm, for three dimensional imagery of lunar surface taken by C640 sensors.

The Terrain Mapping camera (C640 Linear CMOS Array) on board a recently launched spacecraft was successfully operated on October 29, 2008.  Analysis of the first imagery confirms excellent performance of the camera.  The first imagery taken from a height of 9,000 km shows the Northern coast of Australia while the other taken from a height of 70,000 km shows Australia’s Southern Coast.

CMOS Sensor blasted into orbit today.  Eleven scientific payloads were launched with CMOS Sensor playing a major part in two of these.  Five instruments were designed and developed in India, three instruments are from the European Space Agency, one from Bulgaria and two from the United States.  Two of the Indian payloads are:

 

Terrain Mapping Camera (TMC), a CMOS camera that maps the topography of the moon, which helps in better understanding of the lunar evolution process.

 

Hyperspectral Imager (HySI), another CMOS camera, is designed for mapping of the minerals on the lunar surface as well as for understanding the mineralogical composition of Moon’s interior.

 

The sensors for these two cameras were designed and manufactured by CMOS Sensor, Inc.

The engineers at CMOS Sensor, Inc. of Cupertino, California, a major supplier of contact image sensor (CIS) modules to the office equipment markets, are preparing to release an Industrial Linear Scanner (I-cis).  The new i-cis is built from a contiguous row of CMOS linear image sensors using an array of rod lenses to form the image as in CIS modules, but in i-cis the scanned object can be up to 14mm from the input window and the object can be up to three meters wide.　In designing i-cis, CMOS Sensor chose to use its line sensor devices with electronic global shuttering so that i-cis would permit line scan systems integrators to use their usual illumination sources – LED, fiber or fluorescent.  They also designed the rugged aluminum housing to facilitate single or dual side illumination at angles up to 45 degrees and equipped the scan controller to accommodate up to four colors of sequential illumination of unequal brightness to support RGB or other multispectral imaging.

 

ILS can be readily installed in places where traditional line scan cameras would never fit. Unlike line scan cameras, the ILS has no parallax error and no inter-camera misalignment problems.  The ILS scans up to 18,000 lines per second with a resolution of 600dpi providing data through a CameraLink interface.

 

The i-cis family is suitable for inspecting high-speed webs of any type and large-area flat items like glass, plastics and wood.　Ideal for high volume production line applications such as large LCD displays or assembled solar panels, i-cis simplifies implementation of high-speed line-scan inspection systems that improve the ability of production engineers to detect defects and raise throughput quality levels resulting in improving gross margins in manufacturing.

April 2008

CMOS Sensor, Inc. has introduced the C640, a linear image sensor that supports destructive readout, non-destructive readout and power down output modes.  The device has 4000 photodiode elements.  7 x 7 um pixels integrated with a programmable gain amplifier for fine and course gain control, a 12 bit Analog to Digital converter, a voltage regulator, a low-voltage differential amplifier and a timing generator.  Imaging length is 28 mm.  Proprietary technology and readout structure reduce fixed pattern noise, increase dynamic range, improve linearity and employ automatic dark voltage cancellation.  During image capture, the chip enables snapshot operation or start and stop integration for all pixels simultaneously.

CMOS Sensor, Inc. demonstrated the capabilities of it’s latest Industrial Line Scan Camera, i-cis, by imaging printed circuit boards utilizing a linear conveyor.  The advantage over traditional area cameras was evident when dimensioning via holes near the edge of the field of view.
