摘要： A cavity ring down gas sensor is disclosed. In one illustrative embodiment, the cavity ring down gas sensor includes an electromagnetic radiation source (e.g. laser) configured to emit an input beam of light having a wavelength corresponding to an absorption line of a gas to be detected. The input beam of light may be coupled into an optical cavity to amplify an internal beam of light that is reflected about the optical cavity. An optical element may be disposed in the optical cavity at an angled close to, but not at, the Brewster's angle to reflect a relatively small portion of the internal beam of light in the optical cavity to a detector for determining the intensity of the internal beam of light in the optical cavity. When a specified light intensity is reached in the optical cavity, the input beam of light may be shut off or otherwise prevented from entering the optical cavity, and a cavity ring down time decay may be measured. The cavity ring down time decay may be related to the gas concentration of a gas to be detected in the optical cavity.

摘要： An illustrative cavity ring down gas sensor includes an optical cavity for receiving a gas to be detected and at least two electromagnetic radiation sources. The first electromagnetic radiation source may emit a first beam of light having a wavelength corresponding to an absorption wavelength of the gas to be detected, and the second electromagnetic radiation source may emit a second beam of light having a second wavelength that is off of an absorption wavelength of the gas to be detected. The first beam of light may detect a cavity ring down time decay, which is related to the concentration of the gas to be detected. The second beam of light may be used to detect a baseline cavity ring down time decay, which may be used to help increase the accuracy of the sensor by, for example, helping to compensate the concentration of the gas detected by the first beam of light for sensor variations caused by, for example, sensor age, temperature or pressure changes, and/or other conditions.

摘要： A multispectral imaging array system and method of forming the same. A substrate and a group of antennas can be located with respect to one another on the substrate, such that respective gaps are formed between each antenna group and wherein different antenna sizes may be used for different spectral ranges. Additionally, one or more nanowires can be located within one or more gaps among the respective gaps, such that the nanowires in communication with the antennas and the substrate comprise a multispectral imaging system in which the use of the nanowire(s) decreases the thermal time constant and therefore the read out rate from the antennas while decreasing the ambient gas cooling speed relative to the read out rate to increase the manufacturability of the multispectral imaging array system.

摘要： A cavity ring-down sensor having an optical path of mirrors and an interface proximate to a mirror with a normal incidence optical fiber coupling. The interface may be a block of transmissive materials having different indices of refraction for receiving a light beam of normal incidence from an optical fiber and directing the beam into the optical path. The sensor may be used applications where the optical fiber needs to be straight into the sensor without unusual bending because of space limitations. One application of this sensor may be for ground water testing via a narrow well casing.

摘要： A UV flame sensor for detecting a run-on condition in a flame detector tube is disclosed. The UV flame sensor comprises a pair of secondary electrodes that are enclosed in a mesotube to form a breakdown chamber in order to detect the run-on condition. These secondary electrodes are exposed to UV through an aperture in a cathode plate and are energized continuously by a lower voltage. The mesotube is expected to break down when the run-on condition occurs. The secondary electrodes can be placed in the same gas environment as the main electrodes that may take different forms, shapes and locations.
