Abstract: An external signal detection circuit is installed in a new measuring section, and generation and end timing of a readout signal of a spectrometric detector is directly controlled, and a readout signal in synchronization with an external start signal is generated. After input of measurement standby instructions, the external start signal is monitored anytime. Before detection of the external start signal, the new measuring section is shifted to a pause state and after the detection of the external start signal, transition to a measurement state is made. By this configuration, delay time between input time of the external start signal and readout start time of data is defined and valid measurable time at the time of setting short storage time is increased.

Abstract: A spectrometer (10) includes a two-dimensional array of modulatable micro-mirrors (18), a detector (20), and an analyzer (22). The array of micro-mirrors is positioned for receiving individual radiation components forming a part of an input radiation source. The micro-mirrors are modulated at different modulation rates in order to reflect individual radiation components therefrom at known and different modulation rates. The micro-mirror array combines a number of the reflected individual radiation components and reflects the combined components to the detector. The detector is oriented to receive the combined radiation components reflected from the array and is operable to create an output signal representative thereof. The analyzer is operably coupled with the detector to receive the output signal and to analyze at least some of the individual radiation components making up the combined reflection. By using a micro-mirror that receives individual radiation components and then modulates the radiation components at different rates, all of the radiation components can be focused onto a single detector to maximize the signal-to-noise ratio of the detector. A variable band pass filter spectrometer, variable band reject filter spectrometer, variable multiple band pass filter spectrometer, and a variable multiple band reject filter spectrometer utilizing the same invention are also disclosed.

Abstract: A method of breast tissue examination using time-resolved spectroscopy includes the following steps. A support that includes an input port and an output port separated by a selected distance is positioned relative to the examined breast. Locations of the input and output ports are selected to examine a tissue region of the breast. Light pulses of a selected wavelength and duration less than a nanosecond are introduced into the breast tissue at the input port and detected over time at the detection port. Signals corresponding to photons of detected modified pulses are accumulated over time. Values of a scattering coefficient or an absorption coefficient of the examined breast tissue are calculated based on the shape of the modified pulses. The examined breast tissue is characterized based on the values of the scattering coefficient or the absorption coefficient. Absorbing or fluorescing contrast agents may be introduced into the examined tissue. This method may be used in conjunction with x-ray mammography, needle localization procedure or MRI mammography.

Abstract: There is disclosed a Fourier transform spectrometer using a pulsed light source which can be selected from various types of light sources. The spectrometer Fourier-transforms the interferogram obtained by an interferometer to give rise to a spectrum. The spectrometer is characterized in that it includes a means for impulsively lighting up the light source for the interferometer at predetermined intervals of time and a means for extracting the envelope of the output from the interferometer as an interferogram. The spectrometer can further include a means for periodically applying a stimulus to the sample. In this case, time-resolved Fourier transform spectroscopy can be effected. The differential method can also be applied by lighting up the light source for the interferometer at intervals half the intervals at which the stimuli are given and by extracting the output from the interferometer via a band-pass filter and via a lock-in amplifier.

Abstract: An optical spectrum analyzer is provided with a user selectable sensitivity. Required operating parameters are set in response to user selection of sensitivity to permit measurement of an input light beam at the selected sensitivity. Setting the required parameters includes setting a required gain of a video channel to permit measurement of a specified maximum light signal and to provide the selected sensitivity, setting a required video bandwidth of the video channel to provide the selected sensitivity at the required gain of the video channel and setting a sweep rate to provide the selected sensitivity at the required video bandwidth. When the normal bandwidth of the video channel is not adequate to provide the selected sensitivity, the electrical signal is passed through a digital filter having a filter coefficient set to provide the required video bandwidth. A peak detector is incorporated in the video channel to accurately measure signal amplitudes in a fast scanning condition.
