Title:
APPARATUSES AND METHODS FOR APPLYING AN INDELIBLE AND CONTRASTING PATTERN ONTO A CARRIER
Document Type and Number:
WIPO Patent Application WO2001007197
Kind Code:
A9
Abstract:
Methods and apparatus are provided to apply permanent identification markings onto transparent carriers using laser induced vapor deposition technology. This is accomplished by vaporizing material from a marking media carried by a substrate using the heat generated from a laser and transferring the marking material onto a transparent carrier, the markings are dectectable using an optical reader or sensing device like x-ray, thermal imaging, ultrasound, magneto-optic, micro-power impulse radar, capacitance, or other similar sensing means.
