Abstract: An imaging system comprises a wide field of view (FOV) telescope, a narrow FOV telescope, a spectrometer, an imaging detector, an image slicer, and a selection mechanism. The wide FOV telescope is configured to produce a one-dimensional optical image of a broad field of view (FOV) F. The narrow FOV telescope is configured to produce a two-dimensional optical image of a narrow FOV f. The spectrometer is configured to produce a spectrum of a one-dimensional image, and the imaging detector is configured to capture that spectrum. The image slicer is configured to break the two-dimensional optical image into a series of one-dimensional segments. The selection mechanism operable in either of two modes: a wide FOV mode transmitting the one-dimensional optical image to the spectrometer, and a zoom mode transmitting a one-dimensional concatenation of the series of one-dimensional segments to the spectrometer.

Abstract: A DMS-IMS chemical sensing system employs two ion-separation technologies in tandem to extract signals of specific chemicals from the glut of signals present. The sensing system generally includes an atmospheric pressure ion generation system, a Differential Mobility (DMS) system, a time-of-flight IMS (TOF-IMS) system, and an ion detector system. The DMS extracts a narrow range of trace chemicals from an environmental sample for subsequent analysis, and a TOF-IMS then analyzes the resulting narrow range of isolated chemicals, allowing compound-specific detection thresholds at sub-ppb concentrations.
