[Laser] Video Camera/Nightscope, etc. sensitive to IR light?

[John Randall]

All cameras can see IR. Just shine your tv remote into the camera lens and you 
will see white led's. The trick is to get rid of a small glass filter which is 
normally placed infront of the cd imager sensor. Once its removed, your images 
and video however will become a bit washed out in colour. 


This will get you closer to IR.

John

Subject: [Laser] Video Camera/Nightscope, etc. sensitive to IR light?

We’re planning to run some tests using an OSRAM IR Dragon high powered infrared 
LED, and would like to use a video camera to help us sight in on the 
transmitter. Initially, we’ll probably modulate the IR with simple on-off Morse 
Code keying, and will use the video camera to verify LOS to and from various 
locations. Our goal is to determine the most likely sites for a successful VUCC 
attempt into five grids. 


I have a couple of Sony HD camcorders that feature their “Night Shot” technology 
and are sensitive to IR light, but I’m wondering if a Nightscope or other such 
device would be more useful for this application? I’ve even heard of IR rifle 
sights---anyone have any experience with this? 


Thanks in advance.
