RE: Thermal Imaging, Thermal Cameras, The Movie Predator and Now in Your Own Pocket
More cool new tech to play with. I see the FLIR ONE is around £200. Could be useful to a lot of people, e.g. for looking at machine performance or home insulation.
I know that smartphone cameras can see some infrared as they can see remote control LEDs. I don't know if this can be used for anything else.
Sensors in regular digital cameras are sensitive in the near infrared region and they normally have filters in the lens applied in order to reduce or eliminate that sensitivity. This however is not the same as the thermal cameras as they work in a different region of the infrared spectrum called Long-wavelength infrared, so you cannot get your smartphone's camera or a digital camera to record thermal information. Still taking some infrared only photos in the near infrared region by removing the IR filter and blocking the visible light below it can be a fun thing to do as it can produce some really interesting and great looking photos... :)
I didn't think my phone could do the thermal thing, but then your explanation was great. I know there's a camera for the Raspberry Pi that doesn't have an IR filter. Could be good for a security camera. Maybe someone will hack a thermal camera for it too.
The FLIR Lepton thermal imagign sensor is available with a special board for use with Raspberry Pi already... :)
Ah, cool. Not that I'll rush to get one. I have some other things I need to try with my Pi
