32k Super Resolution Modes
Unlike typical bilinear or bicubic interpolation methods, Teledyne DALSA
’s proprietary and patent
-
pending super resolution system derives a balanced, artifact free 32k image that provides higher
detectability, especially for small defects, high MTF (modulation transfer function, also known as
spatial frequency response), low noise and high SNR, all with the responsivity of a 5um pixel. The
combination of camera, CLHS interface and High-Resolution frame grabber enables this
functionality up to 150kHz line rate.
32k SR Mapped
The SR mapped function
utilizes the first stage in Teledyne DALSA’s patented processing chain. The
high-resolution image is created, benefitting the system with higher Full Well, higher SNR and
lower noise.
This mode provides the lowest level of data processing in the Teledyne DALSA system and hence
poses the lowest risk of affecting subsequent user data processing.
Use this mode in the initial setup to evaluate whether your system benefits enough from the 32k
SR operation and to avoid conflicts for your algorithms.
32k SR Detail Restored
The Detail Restored mode, when selected, enables the “SR Strength” (
) parameter for
user adjustment.
With “Detail Restored”, the full Teledyne DALSA patented processing chain is activated. Sub
-pixel
information is extracted and enhanced via the “strength” parameter. This function gradually
increases the system MTF and provides higher effective SNR for small and sub-pixel defects without
affecting noise significantly.
It is highly recommended that the user tests these settings in their own application and adjust the
“strength” (between 0 and 1) to identify the best balance between enhanced detection (higher SNR
for given defects) and potential false positives that subsequent algorithms may identify.
Extended Area Mode
In Extended Area Mode each of the three sensor arrays is output as separate imaging planes. Each
output is 16384 x 128 pixels. However, as the top and bottom arrays have 64 rows, the bottom
half of their images will be blanked out.
