I think basically it works like this. The infrared light is able to penetrate thin clothing. If you have the infrared option turned on during the day, it probably superimposes the images allowing a limited "xray"-ish vision. Like you could see someone's underwear or something. I am not sure what the filter is they are using though. The connectix quickcam (bw & color) is rather sensitive to IR light and can be modified quite easily for infrared viewing. See http://www.refland.com/Qcamtech.htm <http://www.refland.com/Qcamtech.htm> for more information on removing the IR filter from a quickcam. So no, I don't think you could see through foliage too well. I can't remember if it was mentioned on this list, but I remember reading a discussion where someone was talking about using the quickcam in a wearable to see in the dark. If you removed the IR filter and had your own IR light source, it seems like it could work. Jobe -----Original Message----- From: Ben Bay [mailto:] Sent: Wednesday, August 12, 1998 2:45 PM To: '
' Subject: X-Ray vision (was: Get them while you can...) Does anyone know what the operating principle of this is? Is the camera actually 'seeing through' clothes or what? What else could it see through? (ex. see through undergrowth for search & rescue.) Isn't there a way to modify the QuickCam to record infrared? Could this be modified to do the same thing? and finally.. what is the "special filter" mentioned? -Ben -- Subcription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" to
