Modes of Data Acquisition
The Synapse CCD detection system allows for a variety of data acquisition modes. The
correct acquisition mode will depend on the experiment being performed and the data
format required by the user. Data acquisition modes and experimental parameters are
selected by the end-user via SynerJY software.
This section contains a brief description of the acquisition modes currently supported by
Synapse systems. Also provided, is a description of acquisition parameters required to
run each type of experiment. The following page provides a detailed description of the
acquisition parameters. Refer to Appendix C for detailed procedures about conducting
experiments with SynerJY.
CCD Position
In a CCD Position experiment, the spectrometer is set to a specific grating position by the
software. When the experiment is run, the CCD collects data only from the wavelengths
of light that reach the CCD detector. Each column of the CCD is then mapped to a single
wavelength. This data can be viewed as spectral or image data.
Spectral Data
Spectral experiments can be defined to have multiple areas of interest on the CCD array.
In such experiments, each area produces a single spectrum.
CCD Position spectral data is obtained when the signal is binned or summed along each
column in a selected area during acquisition. The resulting data set is a spectrum with a
signal intensity value for each column of pixels or group of binned columns. The
intensities are then recorded and displayed according to the user’s preference as either a
function of pixel number or as a function of the wavelength assigned to each pixel.
Required Parameters: Areas, X-Binning, Integration Time, Accumulations, Gain and
ADC Speed.
Image Data
Image experiments can be defined to have multiple areas of interest on the CCD. In such
experiments, each area results in a separate image.
CCD Position image data is collected by recording the signal of each individual pixel or
binned group of pixels on the CCD array. The resulting set of data is a 3-Dimensional
plot of Intensity as a function of X position and Y Position. For the Synapse CCD
Detection system, the X axis corresponds to wavelength and data can be recorded and
displayed on the X axis as a function of pixels or wavelength. The Y axis represents the
height position along the entrance slit of the spectrometer.
Required Parameters:
Areas, X-Binning, Y-Binning, Integration Time, Accumulations,
Gain and ADC Speed.
