摘要： An apparatus and method for optically detecting whether a substance is present at an inspection site on a base material based on light reflected from the inspection site. A light module generates light of a first wavelength and light of a second wavelength. A first optical transmission medium directs the light of the first wavelength and the light of the second wavelength to the inspection site. A photodetector receives light reflected from the inspection site and generates a reflection signal corresponding to the reflected light. A second optical transmission medium directs the reflected light from the inspection site to the photodetector. A control module has an input for receiving the reflection signal. Responsive to the reflection signal, the control module generates a first inspection site absorption value corresponding to absorption of the light of the first wavelength that was directed at the inspection site and a second inspection site absorption value corresponding to absorption of the light of the second wavelength that was directed at the inspection site. The control module generates an output signal indicating whether the substance is present at the inspection site responsive to the first and second inspection site absorption values.

摘要： An side stream infrared gas analyzer for detecting the concentration of a gaseous component of a substantially gaseous flow stream such as the expired air of a patient under anesthesia. The infrared gas analyzer comprises an infrared energy detector, a sample cell, and an infrared energy source which are designed to be small and to consume relatively little electrical power. The infrared energy detector converts the received incident radiation into at least one electrical signal representative of the received incident radiation and is preferably mounted directly onto a printed circuit board containing signal processing circuitry which processes the electrical detection signals provided by the infrared energy detector. The infrared energy detector also has a first infrared transmissive window on a detection side thereof through which the incident radiation passes for detection. The sample cell is preferably mounted on the detection side of the infrared energy detector and receives at least a portion of the substantially gaseous flow stream from the patient and directs the received portion to a detection volume which shares the first infrared transmissive window of the infrared energy detector on one side thereof. The infrared energy source is then mounted on the side of the sample cell opposite the infrared energy detector so that emitted infrared energy passes through a second infrared transmissive window which is shared by the infrared energy source and a side of the detection volume opposite the infrared energy detector. After passing through the second infrared transmissive window, the infrared energy from the infrared source passes through the detection volume for absorption by the gaseous component and then through the first infrared transmissive window for detection by the infrared energy detector. The concentration of the gas constituent is then calculated from the resulting absorption signal.
