Abstract: Instrument and method for detecting pesticides and other analytes. A sample to be tested is mounted on a cassette and inserted into a housing which is substantially impervious to light, and light from a source within the housing is directed toward the sample to induce fluorescent emission from analyte on the sample. Fluorescent emissions from the sample are monitored with a detector within the housing to detect emissions having a spectral content characteristic of the analyte to be detected. Data from the detector is processed, and information based on the processed data is displayed. In some embodiments, the instrument is calibrated with data from a reference sample of known concentration or density. The detector measures the analyte in units of mass per unit area, and in some embodiments the mass per unit area is converted to units of concentration or density of the analyte in the sample.

Abstract: CT scanning of transportation containers is performed by generating X-rays at various points at the opposite sides of the containers, detecting the X-rays passing through the containers, and analyzing the data received to determine the presence of contraband. The X-rays are generated by modulating a magnetic field through which a high-energy electron beam passes to deflect the beam successively to different targets positioned around the sides of the container, while the electron beam source remains stationary. The X-rays are detected by an array of cells using X-ray responsive storage phosphor material to emit light which is sent to analyzing and comparing equipment. The targets and detectors and the cargo container are moved relative to one another to scan a selected volume of the container.

Abstract: Methods and apparatus for sampling techniques can constantly monitor a spectral output from a broadband source in order to control a central wavelength of interrogation light supplied by the source for input to a sensor. A first portion of light output from the broadband source passes through a controller module for spectral analysis and referencing to provide measurements that can be used as feedback to actively modify a second portion of the light from the source. This modified second portion thereby controls the central wavelength to ensure accurate determination of sensor response signals received at a receiver.

Abstract: A light source is gated ON and OFF in response to a pulsed signal. Photo emissions from the light source are coupled to a material under test. Resonant fluorescent emissions from the material are coupled to a photodiode. Current from the photodiode is coupled into an amplifier system comprising a first and second amplifier stages. The first amplifier stage is gated to a low gain when the light source is turned ON and the gain is increased when the light source goes from ON to OFF. The second amplifier stage has digitally programmable offset and gain settings in response to control signals. The output of the second amplifier stage is digitized by an analog to digital converter. A controller generates the pulse control signal and the control signals.

Abstract: The invention provides a method and device for fluorescent measurement of a sample. The method includes impinging an incident beam having an excitation wavelength and a focus diameter on the sample to yield a laser spot that defines sample volume. The laser spot is displaced relative to sample volume in three dimensional space defined by sample volume. The laser spot is translated across the sample volume in depth direction to detect one or more emitted fluorescence signals from the sample volume. A depth profile and a thickness of the sample carrier obtained from the one or more emitted fluorescence signals, are used for measuring normalized bulk fluorescence. Further, at least one microvolume of interest is obtained from the depth profile, and the incident beam is focused on the microvolume of interest to obtain at least one concentrated emitted fluorescence signal.
