Chapter 6: First Light
Once the NIRvana HS camera hardware has been configured as described in Chapter 5,
Hardware Configuration , operation of the camera is straightforward. For most
applications simply:
• Establish optimum performance using Preview mode;
• Set a target temperature for the NIRvana HS system;
• 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 LightField’s Online Help.
During data acquisition, the sensor 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
Figure 6-1 .
