摘要： Airborne contaminants within a substantially sealed enclosure 12 are detected and measured in situ without interrupting the operation of moving parts 14, 15 and 16 within the enclosure. At least one infrared (IR)-transparent attenuated total reflection (ATR) element, in the form of an optical fibre bundle 20, is disposed in the enclosure to collect contaminants. An IR source 22 is optically coupled to one end of the bundle, and an IR detector 24 is optically coupled to the other end of the bundle. The source and detector, in combination, respond to changes in intensity at the wavelengths of the IR radiation transmitted by the bundle to identify the contaminants and quantities thereof that settle on the bundle.

摘要： A method for the spectral analysis of short optical pulses (12) uses an optical group velocity dispersive medium (14), for example, a low loss single mode optical fiber, to map the optical spectrum (a) of the pulse into the time domain (c, d). One application of this method is used for obtaining a serial, time domain readout of information stored in a photochemical hole burning memory which utilizes a medium with broad hole widths.
