Hack a JVC KY-1900 into a Real-Time Polarimetric Imager #celebratephotography


NewImage

From prutchi on Instructables:

Polarimetric imaging offers a path to develop game-changing applications across a wide range of fields – spanning all the way from environmental monitoring and medical diagnostics to security and antiterrorism applications. However, the very high cost of commercial polarimetric cameras has hampered research and development on polarimetric imaging. This paper presents detailed instructions for converting a surplus 1980s-era, 3-tube color camera into a real-time polarimetric imager. The camera used as the basis for this conversion is widely available in the surplus market for around $50. This trash-to-treasure Instructable will show you how to convert a camera that is suitable only as a prop into a useful scientific instrument, commercial versions of which would be worth many tens of thousands of dollars.

You’ll need the following items to perform this conversion:

  • Working surplus JVC KY-1900 camera (models KY-2000 and KY-2700 seem similar to the KY-1900 and may also be suitable)
  • Ø25.4mm wideband 70T/30R beamsplitter (e.g. Thorlabs BSS10)
  • Ø25.4mm wideband 50/50 beamsplitter (e.g. Thorlabs BSW10)
  • 3D-printed beamsplitter adapter rings
  • Sheet of polarizing plastic (e.g. Edmund Optics 86-188)

We #celebratephotography here at Adafruit every Saturday. From photographers of all levels to projects you have made or those that inspire you to make, we’re on it! Got a tip? Well, send it in!

If you’re interested in making your own project and need some gear, we’ve got you covered. Be sure to check out our Raspberry Pi accessories and our DIY cameras.


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
