The Basler sprint Series Line Scan Cameras includes units with 2k, 4k, and 8k resolution
and different line rates. All sprint variants are based
on a next generation dual line CMOS sensor designed
exclusively for Basler.
The Basler sprint Series is aimed at applications where high
sensitivity, excellent image quality, and the highest
speed are required. This speed and image quality
let sprint camera users increase efficiency and
throughput in many vision applications.
To reach Basler's high goals for the sprint sensor, the
positive properties of current sensor technologies
were combined. The well-known image quality of
CCD sensors was combined with the high speed
of CMOS to achieve a "best of both worlds" result.
The sprint development project resulted in a unique
sensor design with a high QE (quantum efficiency)
of up to 60%, a fill factor of 100%, and a very high
SNR (signal-to-noise ratio) at low light conditions.
This means that users will see very low noise levels
and unique speed levels. A maximum line rate of
140 kHz can be reached at either 2k or 4k resolution.
With 8k resolution a line rate of up to 70 kHz can be
reached. The fact that there is no gap between the
two active lines in the sensor makes it easy to fit
the camera into both existing and new applications
with no spatial artifacts.
The AOI feature lets the user focus precisely on the area
of an object that is important to them. This means
that the amount of data transmitted by the camera
will be reduced and that the image processing
application in the user's host PC will not be overloaded
with unnecessary data. In addition, the user may see a
linear increase in the camera's speed by reducing
the AOI.
The time delayed lime sum feature uses the dual line sensor to scan
each object line twice in a time delayed fashion.
The double information is combined in the sprint's
internal memory and this technique doubles the
sprint's sensitivity. It also significantly reduces
noise and results in a 3 dB increase in the SNR.
With the time delayed line averaging feature, time delayed line summing is
performed and then the doubled information is
averaged. The advantages are an increase of
3 dB in the SNR and an increase of 3 dB in the
dynamic range.
Both horizontal and vertical binning are available.
Either two pixels or four pixels can be binned
together.
DSNU (dark signal non-uniformity) and PRNU
(photo response non-uniformity) can be performed
to correct for the non-homogeneous behavior of
lighting, optics, and the sensor that can be present
in real world applications. Shading or vignetting
caused by lenses can be compensated by the
enhanced shading correction (ESC). The wide
range of the ESC is very helpful for image
processing, especially with larger sensors and
lenses with shorter focal lengths.
A Bayer pattern filter is used to create the color
version of the sprint. One line in the sensor reports
red and green information and the second line
reports green and blue information. Image data
in a raw format is transferred to the frame grabber
where color processing happens in a fast, reliable
way similar to common color area scan cameras.
Several color creation schemes can be implemented.
Depending on the application needs, the active
color concept can focus on speed and reducing
the amount of data, or it can focus on higher color
fidelity. For higher color fidelity, each object line
is scanned twice, thus two times color information
is available for each image point. This approach
has a big advantage because standard lenses
and frame grabbers can be used. Because there
is no gap between the sensor's two active lines,
adapting the camera to your application/object is
easy and no spatial correction is needed.
