Abstract: A method of sensing a process utilizing a sensing apparatus consisting of more than one diode laser having select lasing frequencies, a multiplexer optically coupled to the outputs of the diode lasers with the multiplexer being further optically coupled to a pitch side optical fiber. Multiplexed laser light is transmitted through the pitch side optical fiber to a pitch optic operatively associated with a process chamber which may be a combustion chamber or the boiler of a coal or gas fired power plant. The pitch optic is oriented to project multiplexed laser output through the process chamber. Also operatively oriented with the process chamber is a catch optic in optical communication with the pitch optic to receive the multiplexed laser output projected through the process chamber. The catch optic is optically coupled to an optical fiber which transmits the multiplexed laser output to a demultiplexer. The demultiplexer demultiplexes the laser light and optically couples the select lasing frequencies of light to a detector with the detector being sensitive to one of the select lasing frequencies.

Abstract: The disclosure relates to a substrate material for the improved detection, resolution and imaging of biological material for spectroscopic characterization by Raman of optical imaging spectroscopy. The substrate provides a uniform, optically flat, highly reflective surface which can be made hydrophobic to prevent spreading of the sample and facilitating its optical evaluation. Moreover, the substrate can be coated with a material that does not emit Raman scattered photons when exposed to said illuminating photons. The principles disclosed herein allow a low spectroscopic background particularly suitable for examining small samples or samples having low concentrations of the suspected component.
