1. Introduction:
For the purpose of my Master degree in Mathematics and Science Education I worked on
a project with the Basler High Speed Camera. Together with my supervisor, André Heck
I captured video clips of various fast natural phenomena. While working on this project
we both realized that there are some things that the user of such a camera should have in
mind in order for the videos to look nice and to be able to see with the highest quality the
underlined phenomenon every time. Many factors can influence the quality of the image
and the frame rate. Therefore we decided to write a short and easy guide for the use of
this camera in order to help anyone who wants to use it for educational, or any other,
purposes. In this guide I will first discuss some important features of the Basler A602fc
camera, which is a progressive scan, CMOS, color high speed camera. I continue with a
step-by-step description of how to use the camera and the software that is provided with
it. At the end of this guide there are some reminders and tricks you can apply in order to
get a better quality of the image and ways to achieve high frame rates.
2. The Basler A602fc High Speed Camera
2.1 Conditions for use
It is very important to be careful with this sensitive camera. The housing temperature
during operation of the camera must stay between 0
o
C and 50
o
C. You are advised to
allow sufficient air circulation around the camera to prevent internal heat built-up in your
system. Additional cooling devices are not normally required but in case that are neces-
sary, they should be provided in case the spotlights provide additional heat. The relative
humidity during operation should stay between 20% and 80%.
2.2 Frame rate
This camera can capture up to 100fps in an 8 bit/pixel output mode and up to 50fps in a
16 bit/pixel output mode at a full resolution of 656 (horizontal) × 490 (vertical). However
with a lower resolution and some other adjustments that will be mentioned in the later
chapters this camera can capture much more frames per second. In our project we
managed to capture up to 600 frames per second.
2.2 Cable length
The cable you will use to connect the camera with your computer should be:
Maximum 4,5 m for the IEEE 1394 cable
Maximum 10m for the I/0 cables
You should have in mind that the camera comes with a 6-pin firewire cable to connect to
a desktop computer. This cable however does not work for laptops because this type of
computer usually comes with a 4-pin firewire connector. So in case you want to use the
camera with a laptop make sure you buy the specific firewire cable for laptops, which
allows the camera to be connected with an external power.
