Example apparatuses and methods relating to imaging systems are provided. An example imaging system may include an optical source configured to generate an optical beam, a beam splitter configured to split the optical beam into a reference beam and an object beam, and a beam combiner configured to route a combined beam with reference beam and object beam components along a common path into a target medium. In this regard, the target medium may act upon the combined beam to form a common path interference beam. The example imaging system may further include an imaging sensor configured to receive the common path interference beam and generate common path interference beam data associated with the common path interference beam, and an image data processor configured to analyze the common path interference beam data to generate image data describing the target medium.

Coherent optical imaging for detecting neural signatures and medical imaging applications using common-path coherent optical techniques

A neural imaging system may include an imaging array, an image data processor operably coupled to the imaging array to process image data received from the imaging array, and a beam angle separator disposed between the imaging array and an object being imaged. The beam angle separator may be configured to separate an object beam reflected from the object being imaged into a plurality of reference beams each having different angular separation with respect to the object beam. The image data processor may be configured to generate image data of the object for each one of the reference beams to correspond to a respective different depth within the object.

A magnetoencephalogram (MEG) system is provided for use with a head. The MEG system includes a shell, and three three-axis gradiometers and a computing portion. Each three-axis gradiometer detects a magnetic field vector from a magnetic dipole in the head and generates a respective detected signal based on the respective magnetic field vector. Each three-axis gradiometer is disposed at a respective position of the shell. The computing portion determines a location of the magnetic dipole based on the first detected signal, the second detected signal and the third detected signal.

A system () and method for detecting contaminants in parcels or other mailings (). The contaminants, either genuine or hoax, are detected using the system () that includes a jogger () that shakes the parcels or other mailings (). The system () further comprises a particle sampler () that analyzes the air flow created over the parcels () while the parcels are shaken. The system () and method preferable includes a parcel opening cutter () and a ram () for compressing during the shaking of the parcels. The air flow is sampled in order to detect whether or not a plurality of opened parcels is suspected of including contaminants such as biological threat material.

A field portable mass spectrometer system comprising a sample collector and a sample transporter. The sample transporter interfaces with the sample collector to receive sample deposits thereon. The system further comprises a time of flight (TOF) mass spectrometer. The time of flight mass spectrometer has a sealable opening that receives the sample transported via the sample transporter in an extraction region of the mass spectrometer. The system further comprises a control unit that processes a time series output by the mass spectrometer for a received sample and identifies one or more agents contained in the sample.
