Abstract: Cavity enhanced absorption spectroscopy systems and methods for detecting trace gases. When the frequency of laser light approaches the frequency of a resonance cavity mode, the laser begins to fill the cavity to that mode. Optical intensity inside the cavity reflects total cavity loss when the laser light frequency coincides with the cavity mode transmission peak. The intra-cavity optical power also depends on the coupling efficiency of the laser beam to the particular cavity mode. Measurement of intensities of three optical signals, namely, intensity of the light incident on to the cavity, intensity of the light reflected from the cavity, and intensity of the intra-cavity optical power, with their appropriate normalization advantageously significantly reduce effects of baseline calibration and drift as the normalized signal only depends on total cavity loss, and not the coupling efficiency, as in traditional approaches.

Abstract: Systems and methods for measuring gas flux are disclosed. One method for calculating gas flux includes: receiving a master clock signal from a global positioning system (GPS) module; transmitting a clock synchronization signal that is based on the master clock signal to a measurement subsystem configured to measure environmental data, wherein the measurement subsystem comprises at least two clocks; receiving the environmental data from the measurement subsystem, wherein the environmental data is associated with the at least two clocks; and calculating gas flux based on the environmental data received from the measurement subsystem.

Abstract: Systems and methods for extending the dynamic range of imaging systems, and more particularly fluorescence or luminescence imaging systems, having low optical background, and a linear detector response. Images of a sample at each of a set of exposure times are acquired, a system-level dark estimate for each exposure time is subtracted from each image to form dark-corrected images, and the different exposures (dark-corrected images) are merged into a wider dynamic-range image. Typically merging is performed on a pixel-by pixel basis.

Abstract: An optical mirror element includes an optically transmissive element having a first surface and a second surface, and a reflective coating layer on the first surface that defines a mirror surface. A first portion of the first surface does not include the reflective coating layer such that the first portion defines an optically transmissive window in the mirror surface. A method of forming an optical mirror element having a window portion includes providing an optical element, masking a first portion of a first surface of the optical element, and thereafter applying a reflective coating to the first surface so as to define a reflective surface, wherein the masked portion defines a transmissive region in the reflective surface. The exposed portion of the first surface may be coated with an anti-reflective coating, either before or after the reflective coating is applied.

Abstract: An optical system is disclosed that can be used for fluorescence filtering for molecular imaging. In one preferred embodiment, a source subsystem is disclosed comprising a light source and a first set of filters designed to pass wavelengths of light in an absorption band of a fluorescent material. A detector subsystem is also disclosed comprising a light detector, imaging optics, a second set of filters designed to pass wavelengths of light in an emission band of the fluorescent material, and an aperture located at a front focal plane of the imaging optics. A telecentric space is created between the light detector and the imaging optics, such that axial rays from a plurality of field points emerge from the imaging optics parallel to each other and perpendicular to the second set of filters.
