Abstract:
A system and method of high-speed microscopy using a two-photon microscope with spectral resolution. The microscope is operable to provide two- to five-dimensional fluorescence images of samples, including two or three spatial dimensions, a spectral dimension (for fluorescence emission), and a temporal dimension (on a scale of less than approximately one second). Two-dimensional (spatial) images with a complete wavelength spectrum are generated from a single scan of a sample. The microscope may include one of a multi-beam point scanning microscope, a single beam line scanning microscope, and a multi-beam line scanning microscope. The line scans may be formed using one or more of curved mirrors and lenses. The multiple beams may be formed using one of a grating, an array of lenses, and a beam splitter.

Abstract:
Various implementations of enabling spectroscopy on IR sensors are disclosed. Devices or apparatus are disclosed employing arrays of resonant absorbers to facilitate spectrometry, such as infrared (IR) spectrometry. Some example devices may include multiple resonant absorbers arranged on a substrate along with multiple sensing elements locate near to the resonant absorbers. The resonant absorbers may include multiple absorptive regions where some of the absorptive regions may have an absorptive response that peaks at one wavelength, while others of the absorptive regions may have an absorptive response that peaks at a second, different, wavelength.
Abstract:
The invention relates to a sensor having a filter arrangement, downstream of which there is arranged a detector arrangement, and an evaluating device connected to the detector arrangement. The filter arrangement has at least a first filter, the suspect filter, and at least one second filter, the reference filter(s). The first filter is configured as a band pass filter allowing the passage of a first predetermined band, the suspect band. The at least one second filter is configured as a band pass filter allowing the passage of a second predetermined band(s), the reference band(s). The detector arrangement has at least one detector associated with at least one of the filters. The band passes reference filters are distributed above and below the band pass of the suspect filter. The sensor with advantage could be utilized within the IR band, and could advantageously be used to detect CO2.
