2.1 NIRvana HS Camera
The NIRvana HS camera, shown in Figure 2-2 , is regulated by an internal controller
which receives commands from the host computer/software and converts them to
appropriate camera control signals, including synchronizing the operation of the
NIRvana HS system with the rest of an experiment.
Figure 2-2: Typical NIRvana HS Camera
In addition, the internal controller converts analog optical data acquired by the sensor
into digital data which is then delivered to the host computer and data acquisition
software being used. Read rate, exposure time, and regions of interest for NIRvana HS
cameras are some of the parameters that are configured using the data acquisition
software on the host computer.
This section provides detailed information about the NIRvana HS camera.
2.1.1 Focal Plane Array (FPA) Sensor
The NIRvana HS camera incorporates a 640 x 512 (20 x 20

m pixels) InGaAs Focal
Plane Array (FPA) that is equipped with four-port differential readouts. The sensor’s
excellent response and outstanding sensitivity in the 0.9

m -1.7

m spectrum make it
particularly well suited for Near-InfraRed (NIR) imaging applications.
Additional key features of the FPA sensor include:
• Readout rates of 3.125 MHz, 12.5 MHz, and 25 MHz capable of 32, 129, and 258
frames per second, respectively;
• Deep cooling to -55°C which reduces the dark signal and enables long
integration times.
