Abstract
A system for monitoring an energy beam burn through has a sheet formed of a material approximately transparent to optical radiation at a desired operating wavelength. A light detector is attached to the sheet. A coating is applied to the sheet and the light detector, wherein penetration of the coating by a light source allows the light source to scatter within the sheet. A response unit is coupled to the detector unit for signaling an alarm when the light detector senses the light source of a predetermined level.
Claims16
A system for monitoring an energy beam burn through comprising:
- a sheet formed of a material approximately transparent to optical radiation at a desired operating wavelength;
- a light detector attached to the sheet;
- a coating applied to the sheet, the coating having an outer surface having a low adsorptivity for the operating wavelength of the optical radiation received by the outer surface and an inner surface for preserving the optical radiation within the sheet that has penetrated through the coating;
- and
- a response unit coupled to the detector unit for signaling an alarm when the light detector senses optical radiation of a predetermined level.
A system for monitoring an energy beam burn through comprising:
- an enclosure formed of a material approximately transparent to optical radiation at a desired operating wavelength;
- at least one light detector attached to the enclosure;
- a coating applied to the enclosure and the light detector, wherein penetration of the coating by a light source allows the light source to scatter within walls forming the enclosure;
- and
- a response unit coupled to the detector unit for signaling an alarm when the light detector senses the light source of a predetermined level;
- wherein the enclosure comprises a plurality of sheets formed of a material approximately transparent to optical radiation at a desired operating wavelength coupled to form the enclosure, the coating applied to each of the plurality of sheets, the light detector attached to one of the sheets.
A method of detecting when a light source has deviated from a desired pathway comprising:
- attaching a detector for sensing light on a sheet of material approximately transparent to optical radiation at a desired operating wavelength;
- applying a coating to the sheet, wherein the coating has an outer surface having a low adsorptivity for the operating wavelength of the light source received by the outer surface and an inner surface for preserving the light source within the sheet that has penetrated through the coating, wherein penetration of the coating by the light source allows the light source to scatter within the sheet;
- and
- detecting the within the sheet by the detector.
