Description
Overview
FX17 camera is built around the monochrome InGaAs image sensor. It is designed for standard applications in
industrial and laboratory use. FX17 works in a push-broom mode, and collects hyperspectral data in the NIR (950 to
1700 nm) region through single fore optics.
There are two versions of the FX17 camera:
• FX17 with Camera Link interface
• FX17e with GigE interface
These specifications apply to all FX17 camera versions.

Image size reduction Multiple Regions of Interest (MROI)
Trigger modes Opto isolated trigger input and opto isolated strobe
output
Image correction
The camera includes the following image corrections:
• Offset and hot pixel correction
• Automatic Image Enhancement (AIE) means that spectral calibration will be the same for every FX camera, and
that smile and keystone will be corrected to practically zero for all cameras.
A customer with several cameras can replace one camera with another and still have the same spectral calibration
and smile/keystone without additional calibration.
All the corrections are enabled by default.
Image size reduction
The image sensor in FX series cameras is larger than the actual image size. Therefore the image area on the sensor
is defined using the Region of Interest (ROI) feature, and the ROI values are provided in the calibration pack. ROI
feature is reserved for this purpose alone, and the values must not be changed.
You can use Multiple Regions of Interest (MROI) feature to define one or several regions of interest. Using MROI
feature requires 1 x 1 binning.
If you use AIE together with MROI, there must be additional 3 rows in the beginning and in the end of each MROI to
prevent corruption. These extra rows must then be discarded in data processing as their data may be invalid.
See the technical notes Setting MROI's in FX10/10e and FX17/17e and Maximum frame rates in FX10/10e and
FX17/17e for more information.

Software Options
Lumo Software
Lumo is a family of software products for hyperspectral sensor data acquisition.
• Lumo Recorder, for when there is no Specim scanner used in the setup
• Lumo Scanner, for when there is a Specim scanner in use
With Lumo Software you can select camera and scanner, adjust acquisiton parameters, and save raw data of the
camera. It can also control other external devices, required for certain sensors, such as thermal calibrator, triggering
electronics, motors, and so on.
Lumo Software has a built-in scripting and sequential workflow engine controlling all the steps and automation to be
performed for each measurement.
For instructions on how to use your Lumo software, refer to the relevant Lumo Software User Manual.
SpecSensor SDK
SpecSensor SDK is a unified SDK for all our cameras, and it is typically used by OEM and integrators. C style API
can be used from different programming languages.
SpecSensor SDK sends commands to cameras and gets the frames from the cameras, however it does not have a GUI
or record data to the disk.
For instructions on how to use your Specim SDK, refer to the SpecSensor SDK User Manual.
ASCII Commands
the Camera Link version of the FX camera can be controlled with ASCII commands, for example in cases where
hyperspectral imaging is intregated in an existing ASCII based system or when required features are not supported by
LUMO or LUMO SDK Software.
ASCII commands are availabe in separate ASCII documentation. Note, that Specim does not provide support
packages for ASCII use cases.
GigE Vision
GigE version of the FX camera is complient with GigE Vision interface standard, which is a global standard for
video transfer and device control over Ethernet networks. For more information, refer to GigE Vision Standard
Specification.

Image Aqcuisition
Readout Modes
The FX cameras provide two different readout modes:
•Sequential readout: Frame time is the sum of exposure time and readout time. Exposure time of the next image
can only start if the readout time of the current image is finished.
•Simultaneous readout (interleave): The frame time is determined by the maximum of the exposure time or
of the readout time, which ever of both is the longer one. Exposure time of the next image can start during the
readout time of the current image.
The following figure illustrates the effect on the frame rate when using either the sequential readout mode or the
simultaneous readout mode (interleave exposure).
Figure 13: Frame rate in sequential readout mode and simultaneous readout mode
Sequential readout mode For the calculation of the frame rate only a single formula applies: frames per second equal
to the inverse of the sum of exposure time and readout time.
Simultaneous readout mode (exposure time is less than readout time) The frame rate is given by the readout time.
Frames per second equal to the inverse of the readout time.
Simultaneous readout mode (exposure time is greater than readout time) The frame rate is given by the exposure
time. Frames per second equal to the inverse of the exposure time.
The simultaneous readout mode allows higher frame rate. However, if the exposure time greatly exceeds the readout
time, then the effect on the frame rate is neglectable.
Note: In simultaneous readout mode image output faces minor limitations. The overall linear sensor reponse
is partially restricted in the lower grey scale region.
Note: When changing readout mode from sequential to simultaneous readout mode or vice versa, new
settings of the BlackLevelOffset and of the image correction are required.

Sequential readout
By default the camera continuously delivers images as fast as possible ("Free-running mode") in the sequential
readout mode. Exposure time of the next image can only start if the readout time of the current image is finished.
Figure 14: Timing in free-running sequential readout mode
When the acquisition of an image needs to be synchronised to an external event, an external trigger can be used. In
this mode, the camera is idle until it gets a signal to capture an image.
Figure 15: Timing in triggered sequential readout mode
Simultaneous readout (interleave exposure)
To achieve highest possible frame rates, the camera must be set to "Free-running mode" with simultaneous readout.
The camera continuously delivers images as fast as possible. Exposure time of the next image can start during the
readout time of the current image.
Figure 16: Timing in free-running simultaneous readout
mode (exposure time is greater than readout time)
Figure 17: Timing in free-running simultaneous readout
mode (exposure time is greater than than readout time)
When the acquisition of an image needs to be synchronised to an external event, an external trigger can be used. In
this mode, the camera is idle until it gets a signal to capture an image.
