Optical fibers are utilized to provide high efficiency, spatially resolved coupling of light from collection optics to an imaging spectrometer. In particular, a micro lens array may be utilized to couple light from multiple spatial locations into individual optical fibers. At the opposite end of the fiber bundle, the fibers are packed tightly together to send the light into an imaging spectrograph. The light that enters this spectrograph maintains its spatial separation, for instance, along the array dimension and is spectrally dispersed, for instance, along a dimension orthogonal to the array dimension. This spatially separated, wavelength resolved light can then be recorded on a two dimensional detector such as a CCD camera.

Cosmic spike filters are provided, which remove noise spikes in spectral data. Spikes are eliminated by locating, smoothing and filtering the spikes using replicates to improve the accuracy of the spike detection process compared to when only one replicate is used. Cosmic spike filters are also provided that combine a data collection approach and a statistical approach to remove cosmic spike noise from the collected signal without distorting the true signal. Still further, a statistical approach is provided to identify and remove negative peaks from a spectrum, where the negative peaks are caused by bad pixels in a charge coupled device.

A small area electrostatic aerosol collector combines electrostatic collection of aerosol particles and electrohydrodynamic spraying of fluid so that a sample collected electrostatically can have fluid applied thereto. The fluid may assist with disaggregation and/or desalinization of biological material collected onto a sample substrate. A controller associated with the collector may control an electrostatic charge device and a spraying device such that the charge device and spraying device may operate in alternating fashion, or the charge device and spraying device may operate simultaneously. Further, mechanical systems are provided, for the disaggregation of particulate clusters collected onto a sample substrate.

An open circuit voltage photodetector comprises a photovoltaic device including a photovoltaic junction, and a transistor. The photovoltaic device is connected to the gate terminal of the transistor to input an open circuit voltage of the photovoltaic device to the gate terminal. An array of such photodetectors and a readout integrated circuit forms an image sensor. In a photodetection method, an open circuit voltage is generated in a photovoltaic device in response to illumination by incident radiation, and the open circuit voltage is applied to a gate terminal of a transistor to modulate a channel current flowing in a channel of the transistor. A readout electronic circuit may be fabricated with an extra transistor, and a photovoltaic device disposed on the readout electronic circuit and electrically connected to apply an open circuit voltage of the photovoltaic device to a gate of the extra transistor.

A lateral interband Type II engineered (LITE) detector is provided. LITE detectors use engineered heterostructures to spatially separate electrons and holes into separate layers. The device may have two configurations, a positive intrinsic (PIN) configuration and a BJT (Bipolar junction transistor) configuration. The PIN configuration may have a wide bandgap (WBG) layer that transports the holes above a narrow bandgap (NBG) absorber layer that absorbs the target radiation and transports the electrons. The BJT configuration may have a WBG layer operating as a BJT above an NBG layer. In both configurations, the LITE design uses a Type II staggered offset between the NBG layers and the WBG layers that provides a built-in field for the holes to drift from an absorber region to a transporter region.

A system and method indicate capability for detecting methane leaks inside buildings. This approach provides the ability to detect methane behind high efficiency coated windows and can extract methane concentration (rather than CL). Lock-in imaging technologies can facilitate lower laser transmitter power. A field deployable, hand held prototype sensor for use in remote sensing a appropriate standoff distances can support operational testing. Distance infrared imaging of methane is feasible. Fully characterized real time image of a methane cloud offers operational advantages in accuracy and safety as compared to current sensors
