Mobile Phone Camera – Cyborg Astrobiologist: May Help Detect Extraterrestrial Life

Wed September 25, 2013

Samsung  SGH A767

Samsung SGH A767

In the study and search for life in the universe, astrobiologists are inundated with tremendous amount of images from other planets, i.e. data overload.

Recently, Patrick McGuire (Freie Universität, Berlin) and his astrobiology team of researchers from Malta, Spain and the United States, created the ‘Cyborg Astrobiologist’ which is a novel, hybrid part-human, part-machine visual system” that uses a simple mobile phone camera” to help crunch the data/ images and facilitate the search for evidence of extraterrestrial life.

At McGuire et al’s field test in West Virginia, USA, the Astrobiology phone-camera system sends images wirelessly by Bluetooth communications to a nearby laptop computer to automatically build an image libary with examples of different terrain for the image compression analysis.

  • The phone-camera for McGuire et al’s field test was a Samsung SGH A767 with 1280×960 RGB color images.
  • The laptop was a Dell Inspiron 9300.

The Cyborg Astrobiologist’s image-compression system involves the following key functions:

Paul Harcourt Davies: Understanding Bokeh Part 2

Sun September 22, 2013

Here is Part 2 of Paul Harcourt Davies’ Bokeh article published at Imaging Resource.

It gets a little more complicated now with “Circle of confusion.” He discusses why often cameras with small sensors cannot give the same bokeh as those using larger sensors and how to use image stacking to get both great bokeh and amazing depth of field. I also learned a neat trick: choose a simple clutter-free background so you can use a smaller aperture (because the background is already clutter-free, you don’t need to blur it so much with a large aperture) to get more depth-of-field and therefore get more of your subject in focus.

As in Part 1, the article is accompanied by some beautiful images to illustrate the various points.

I especially love his parting advice: “It’s too easy to listen to what others tell you with apparent confidence about subjective qualities such as sharpness and bokeh. Remember that what matters in your photography is what you like — whether it’s good, bad, creamy, latté, macchiato or whatever. It’s your taste, so enjoy it!

Could Graphene Revolutionize Image Sensors?

Wed September 18, 2013

The smart people at MIT, Columbia University and IBM’s T. J. Watson Research Center have apparently succeeded in increasing the responsivity (the amount of light that is actually converted into an electrical current) of graphene in photodetectors that convert optical signals to electrical signals in integrated optoelectronic computer chips. (Optoelectronic computer chips use light rather than electricity to move data, drastically reducing their power consumption and heat production.) When graphene is used integrated in a silicon chip, the optoelectronic devices become much simpler in design than those made from other materials and could lead to optoelectronic chips that are simpler and cheaper to manufacture.

The standard way to increase a photodetector’s responsivity is to apply a voltage across it but the voltage will inevitably induce a slight background current that adds “noise” to the detector’s readings. The new design uses a “waveguide” (a silicon channel) etched into the surface of a chip to increase the responsivity without requiring the application of a voltage. The researchers hope that, with even better engineering — thinner electrodes, or a narrower waveguide — they can manufacture a photodetector with still higher responsivity.

Read the article at: mitnews.

Editor’s note: Just wondering: Would the use of graphene and “waveguide” technology eventually migrate to image sensors? By simplifying the design and increasing the responsivity of the sensor, could the issue of noise at high ISOs become a moot point — irrespective of image sensor size? An intriguing thought.

History Channel: Know Where You Stand

Sat September 14, 2013

Here’s an interesting documentary from the History Channel 9and created by Seth Taras) locating historical spots that you may not know of even as you stand right on top of it. I especially like the one on the fall of the Berlin Wall which once divided Germany into two nations and where now stands a bus stop.

Landsat Photography Leads to Newly Discovered Vast Water Reserves in Drought-Prone Northern Kenya

Thu September 12, 2013

This video presents “G2009 120 Landsat Flyby MASTER youtube hq.”

  • “The Landsat program is the longest continuous global record of the Earth’s surface, and continues to deliver both visually stunning and scientifically valuable images of our planet.
  • This short video highlights Landsat’s many benefits to society.”

Thanks to the satellite photography of Earth’s land surface, via Landsat, providing the optical satellite imagery in the RTI’s WATEX mapping system, the natural resources exploration firm – Radar Technologies International (RTI) – recently discovered vast water reserves in drought-prone northern Kenya.

The aquifers were detected with the WATEX System, RTI’s state-of-the-art, space-based exploration technology.
