Dual optical fiber device
First Claim
1. A device for transmitting electromagnetic radiation to a radiation sensitive component, receiving output radiation from said component and transmitting said output radiation substantially unattenuated to a radiation measuring, transducing, recording or retransmitting component, which device comprises a first cladded optical fiber having a proximal end and a distal end, said proximal end being adapted to receive source radiation and said distal end having a exposed tip which touches but is not integrally joined to an exposed intermediate portion of a second cladded optical fiber having a proximal end and a distal end, the touch contact between said tip and the exposed portion of said second optical fiber forming a highly directional radiation-transmissible junction, the proximal end of said second optical fiber being adapted to be attached to a radiation sensitive component such that the output radiation from said radiation sensitive component passes substantially unattenuated along said second optical fiber and through said junction to said radiation measuring, transducing, recording or retransmitting component, said junction being encased in a opaque, radiation reflective jacket.

Abstract
A device for transmitting electromagnetic radiation to a radiation sensitive component and receiving output radiation from said component comprising a radiation-transmissible junction formed by contacting the tip of a first optical fiber with an intermediate portion of a second optical fiber, said junction being encased in an opaque, radiation reflective jacket. A method for determining a desired parameter using such device is also disclosed.

- 10. A method for determining a desired parameter which is a function of the output radiation of a radiation-sensitive component, which comprises transmitting electromagnetic radiation from a source into a device comprising a first cladded optical fiber having a proximal end and a distal end with an exposed tip which substantially contacts an exposed intermediate portion of a second cladded optical fiber having a proximal end and a distal end, said contact forming a radiation-transmissible junction which is encased in an opaque, radiation reflective jacket, said radiation entering the device through the proximal end of said first optical fiber, passing along said first optical fiber and through said junction into said second optical fiber towards the distal end thereof, a major proportion of any radiation not directly passing into said second optical fiber being internally reflected thereinto by the reflective jacket, impinging upon said radiation-sensitive component attached to the distal end of said second optical fiber, causing said component to emit a signal having at least one characteristic dependent upon the parameter to be measured, and said signal passing substantially unattenuated through said second optical fiber toward the proximal end thereof whereby the desired determination is made with the aid of a radiation-detector attached to the proximal end of said second optical fiber.
