A live biological specimen is imaged by generating a plurality of light sheets; directing the plurality of light sheets along an illumination axis through the biological specimen such that the light sheets spatially and temporally overlap within the biological specimen along an image plane, and optically interact with the biological specimen within the image plane; and recording, at each of a plurality of views, images of the fluorescence emitted along a detection axis from the biological specimen due to the optical interaction between the light sheets and the biological specimen. The temporal overlap is within a time shift that is less than a resolution time that corresponds to a spatial resolution limit of the microscope.

A miniaturized counterfeit detector provides multiple tests to ascertain the authenticity of currency in a rapid fashion. The miniaturized counterfeit detector comprises one or more sensors for magnetic ink testing. One or more backlights, illuminators or both may be provided for visual inspection of watermarks, florescent or other anti-counterfeiting features. The miniaturized counterfeit detector may be fastened to a surface and does not obstruct manipulation of currency to improve testing speed, especially when a number of currency items, such as banknotes or bills, are being tested.

The present invention relates to a fluorescent image system capable of generating white light by mixing three monochromatic lights, i.e. red, green and blue monochromatic lights, having a narrow band wavelength, instead of white light of constant wavelength; providing a fluorescent image-use light source that generates a mixed light by adding a fluorescent excitation light source suitable for fluorescent substances; and photographing a general image and fluorescent image simultaneously with the light sources. The fluorescent image system includes a monochromatic light source to generate white light by mixing red, green and blue monochromatic lights, and a fluorescent excitation light source for fluorescent images; and includes a mixed light source to provide a mixed light which mixes monochromatic light and fluorescent light, and an image photographing device which separates the wavelengths of visible light and fluorescent light in the mixed light, and photographs a general image, fluorescent image and mixed image.

Embodiments herein relate to water in fuel sensing systems that can be mounted on-vehicle. In an embodiment, a water in fuel sensing system is included having a light source, a light detector, and a sensor controller, wherein the sensor controller is in signal communication with the light detector and the sensor controller is configured to evaluate signals received from the light detector, identify water droplets based on the signals received from the light detector, record information regarding the classified water droplets, and generate an estimate of an amount of water in a fuel. Other embodiments are also included herein.

An optical sensor may have multiple detection channels to detect different characteristics of a fluid. For example, an optical sensor used in industrial cleaning and sanitizing applications may have multiple detection channels to detect when a system is both clean and properly sanitized. In one example, an optical sensor includes an optical emitter that directs light into a fluid, a first optical detector that detects light transmitted through the fluid, a second optical detector that detects light scattered by the fluid, and a third optical detector that detects fluorescent emissions emitted by the fluid. The optical emitter and optical detectors can be positioned around an optical analysis area. The optical sensor may include filters that control the characteristics of light detected by each of the optical detectors.
