Chapter 6: LightField First Light
Once the Lansis camera has been configured as described in
, acquiring data using LightField is straightforward. For most applications,
simply:
•
Establish optimum performance using Preview mode;
•
Set a target camera temperature;
•
Wait until the system’s temperature has stabilized;
•
Acquire live data in Acquire mode.
Additional considerations regarding experiment setup and equipment configuration are
addressed in the LightField Online Help.
During data acquisition, the CCD array is exposed to a source and charge accumulates
in the pixels. After the defined exposure time, the accumulated signal is readout of the
array, digitized, and then transferred to the host computer. Upon data transfer, the data
are displayed and/or stored via the application software. This sequence is illustrated by
the block diagram shown in
.
