6.1.2 Progressive Scan
All cameras of the SXG series are equipped with Progressive Scan.
Pixel
Active Area (Photodiode)
Storage Area
Microlens
Progressive Scan means that all pixels of the sensor are reset and afterwards exposed
for a specied interval (texposure).
For each pixel an adjacent storage area exists. Once the exposure time elapsed, the
information of a pixel is transferred immediately to its storage area and read out from
there.
Due to the fact that photosensitive surface gets "lost" by the implementation of the storage
area, the pixels are mostly equipped with microlenses, which focus the light to the pixels
active area.

6.1.3 Readout Modes
The Kodak sensors, used in Baumer SXG cameras, are subdivided into four Taps.
Due to Baumer's integrated calibration technique, these taps are invisible within the re-
corded images, but affect the operation and the rate of the readout process and therewith
the readout time (treadout).
Quad Mode6.1.3.1
On quad readout mode all four taps are read out simultaneously as displayed in the sub-
sequent gure.
The data of all pixels of one tap are moved to the output register and afterwards trans-
fered to the memory.
Once the information have left the output register, the readout is done.
This mode provides the full potential of the sensor and leads to the maximum frame
rate.
Dual Mode6.1.3.2
On dual readout mode two taps (Tap 1 + Tap 2 and Tap 3 + Tap 4) are combined.
The data of all pixels of one tap are moved to the output register and afterwards trans-
fered to the memory.
Once the information have left the output register, the readout is nished.
Due to the fact, that more data needs to be read out, the treadout is increased compared to
the quad readout mode.
It is considered: treadout(Dual Mode) ≈ 2 × treadout(Quad Mode)

Single Mode6.1.3.3
In single readout mode all taps are combined as displayed in the subsequent gure.
The data of all pixels of the sensor are moved to the output register and afterwards trans-
fered to the memory.
Once the information have left the output register, the readout is done.
Due to the fact, that the complete sensor needs to be read out, the readout time treadout is
increased compared to quad and dual readout mode.
It is considered: treadout(Single Mode) ≈ 4 × treadout(Quad Mode)

Timings6.2
The image acquisition consists of two seperate, successively processed components.
Exposing the pixels on the photosensitive surface of the sensor is only the rst part of the
image acquisition. After completion of the rst step, the pixels are read out.
Thereby the exposure time (texposure) can be adjusted by the user, however, the time need-
ed for the readout (treadout) is given by the particular sensor and image format.
Baumer cameras can be operated with two modes, the Free Running Mode and the
Trigger Mode.
The cameras can be operated non-overlapped*) or overlapped. Depending on the mode
used, and the combination of exposure and readout time:
Non-overlapped Operation Overlapped Operation
Here the time intervals are long enough
to process exposure and readout succes-
sively.
In this operation the exposure of a frame
(n+1) takes place during the readout of
frame (n).

6.2.1 Free Running Mode
In the "Free Running" mode the camera records images permanently and sends them to
the PC. In order to achieve an optimal (with regard to the adjusted exposure time texposure
and image format) the camera is operated overlapped.
In case of exposure times equal to / less than the readout time (texposure ≤ treadout), the maxi-
mum frame rate is provided for the image format used. For longer exposure times the
frame rate of the camera is reduced.

6.2.2 Trigger Mode
After a specied external event (trigger) has occurred, image acquisition is started. De-
pending on the interval of triggers used, the camera operates non-overlapped or over-
lapped in this mode.
With regard to timings in the trigger mode, the following basic formulas need to be taken
into consideration:
Case Formula
texposure < treadout
(1) tearliestpossibletrigger(n+1) = treadout(n) - texposure(n+1)
(2) tnotready(n+1) = texposure(n) + treadout(n) - texposure(n+1)
texposure > treadout
(3) tearliestpossibletrigger(n+1) = texposure(n)
(4) tnotready(n+1) = texposure(n)
6.2.2.1 Overlapped Operation: texposure(n+2) = texposure(n+1)
In overlapped operation attention should be paid to the time interval where the camera is
unable to process occuring trigger signals (tnotready). This interval is situated between two
exposures. When this process time tnotready has elapsed, the camera is able to react to
external events again.
After tnotready has elapsed, the timing of (E) depends on the readout time of the current im-
age (treadout(n)) and exposure time of the next image (texposure(n+1)). It can be determined by the
formulas mentioned above (no. 1 or 3, as is the case).
In case of identical exposure times, tnotready remains the same from acquisition to acquisi-
tion.

Overlapped Operation: t6.2.2.2 exposure(n+2) > texposure(n+1)
If the exposure time (texposure) is increased form the current acquisition to the next acquisi-
tion, the time the camera is unable to process occuring trigger signals (tnotready) is scaled
down.
This can be simulated with the formulas mentioned above (no. 2 or 4, as is the case).

6.2.2.3 Overlapped Operation: texposure(n+2) < texposure(n+1)
If the exposure time (texposure) is decreased from the current acquisition to the next acquisi-
tion, the time the camera is unable to process occuring trigger signals (tnotready) is scaled
up.
When decreasing the texposure such, that tnotready exceeds the pause between two incoming
trigger signals, the camera is unable to process this trigger and the acquisition of the im-
age will not start (the trigger will be skipped).

Notice
Both data ports supports Power over Ethernet (38 VDC .. 57 VDC). Both ports can be
connected to a PoE power sourcing equipment however only one port will be used to
power the camera.
For the data transfer, the ports are equal. For Single GigE connect one Port and for Dual
GigE connect the second Port additionally. The order does not matter.

Caution
Provide adequate dissipation of heat, to ensure that the temperature does
not exceed +60°C (+140°F).
The surface of the camera may be hot during operation and immediately
after use. Be careful when handling the camera and avoid contact over a
longer period.
As there are numerous possibilities for installation, Baumer does not speciy a specic
method for proper heat dissipation, but suggest the following principles:
operate the cameras only in mounted condition▪
mounting in combination with forced convection may provide proper heat dissipation▪
*) Please refer to the respective data sheet.
