Laser diode beats IR reader.

Teee heee! Look what I found!

Any camera with image intensifier is totally blinded by a laser diode directed into it.

Any prizes for guessing what this means?!!!!!!

Spec's maybe . ATB DErek

where did you find the info carl ?

[Winnebago Nut]

Found a site where a guy has been testing this idea. He has a few pictures of the results he got almost at the bottom of a very long page. Follow this link [URL]www.naimark.net/projects/zap/howto.html[/URL].ATB Derek

So it's only temporary, and requires accurate aim at the instant that the photo is taken. Not convinced, unless you happen to live/work next to a tax collection point.

I have a wide angle Inra red illuminator for night time use with security cameras.
It has close on 100 high brightness leds inside.
Pretty sure that it would blind a specs cam and dosent have to be aimed to well.
Worth a shot methinks.

This is a fascinating subject and it could conceivably be a saviour to people like me, so long may the research continue

Servo motor propelled prism + laser diode = wide laser spread.

[chimburt]

indeed the mechanics/electronics of prism etc. are possible, if a little complex, but what chance of getting the spread and/or timing right in a moving vehicle and with the camera at an unknown elevation in relation to the road?

prefer the sound of the security lamp, if you can get enough juice out of it, and if it's the right wavelength light to saturate the camera.

laser diodes work pretty well at blinding ccds, depending on wavelength and intensity you can knock out the cameras we use at work for just a short space of time or until the unit is reset, which would be a nifty result

however the aim the beem thing is not a starter, IMO, and you'd get more consistent results if you had the equivalent of a fog light at a wavelength not visible to the naked eye with a decent spread.

please don't let me put anyone off though. i'll be in the queue with a handfull of readies if anyone can build something that will be reliable.

880nm wavelength is the output frequency of the security light ive got.
Designed to illuminate totally blacked out areas.
Tried it on lots of different black/and white video cams, blinds em a treat.
Question.
Is specs colour or black/white?
If its colour then its a non starter as most colour cams arent sensitive to Ir.
