摘要： A method of detecting contaminants on a window surface of a viewing system comprises the steps of: reflecting light off of contaminants on the window surface; capturing the reflected light in an image; converting the image into image data; and processing the image data to detect the contaminants on the window surface. Also, apparatus for detecting contaminants on an external surface of a window of a viewing system comprises: at least one light source for reflecting light from contaminants on the external surface; an imager for capturing an image of the reflected light and converting the image into image data; and a processor for processing the image data to detect the contaminants on the external surface. The apparatus may be embodied in a viewing system wherein the imager also captures images of a scene of the viewing system both including the light reflected from the contaminants and not including light reflected from contaminants; and the processor processes both of image data of the scene excluding reflected light from the contaminants, and image data of the scene including reflected light from the contaminants to detect the contaminants on the external surface.

摘要： A method of detecting a combustion chemical in a region and setting an alarm based on concentration levels of the combustion chemical comprises the steps of: monitoring the region for a combustion chemical with a sensor having a measurable parameter which changes in value proportional to concentration levels of the monitored combustion chemical, the measurable parameter being ambient temperature dependent; generating an ambient temperature measurement of the sensor; reading the measurable parameter and ambient temperature measurement; processing the measurable parameter and ambient temperature measurement readings to generate a temperature compensated concentration level of the monitored combustion chemical; and setting an alarm based on the generated temperature compensated concentration level. A fire detector unit for implementing the foregoing described method is also disclosed.

摘要： In one aspect, methods of determining a size distribution of water droplets in a cloud are described herein. In some embodiments, a method of determining a size distribution of water droplets in a cloud comprises sampling a depth of the cloud with a beam of electromagnetic radiation, measuring a scattering signal of the electromagnetic radiation returned from the cloud over a range of field of view angles to provide a measured scattering curve [ptotal(θ)], removing a portion of the measured scattering curve, replacing the removed portion with an extrapolation of the remaining measured scattering curve to provide an estimated scattering curve, and determining a first estimate droplet size distribution [n(1)(D)] from the estimated scattering curve.

摘要： In one aspect, methods of determining a size distribution of water droplets in a cloud are described herein. In some embodiments, a method of determining a size distribution of water droplets in a cloud comprises sampling a depth of a cloud with a beam of electromagnetic radiation, measuring echo intensities of the electromagnetic radiation returned from the cloud with a detector, determining a measured optical extinction coefficient from the measured echo intensities, determining a measured backscatter coefficient from the measured echo intensities, determining a lidar ratio from the measured optical extinction coefficient and the measured backscatter coefficient, determining from the lidar ratio a value pair comprising a shape parameter (μ) and median volume diameter (DMVD) of the water droplets, and determining a size distribution of the water droplets using the value pair (μ, DMVD).
