C11440-22CU/C11440-22CU01 Instruction manual_Ver.1.4
(5) Frame rate (readout speed)
The FL-400 realizes both low noise (1.0 electrons (median) 1.6 electrons (r.m.s)) and
high speed readout (100 frame/s with 2048 pixels x 2048 pixels) simultaneously, by a
split readout scheme in which the top and the bottom halves of the sensor are readout
independently, and the data of each horizontal line is read by 2 lines of column
amplifier and A/D in the top and the bottom in parallel and simultaneously.
(6) Real-time correction functions
When using the camera, there is a case that shading caused by uneven illumination or
optics is not negligible in the image. Also, there are a few pixels in FL-400 that have
slightly higher readout noise performance compared to surrounding pixels. For those
cases, the camera has real-time offset level, shading and defective pixel correction
features to further improve image quality. The correction is performed in real-time
without sacrificing the readout speed at all.
(7) Interface
This camera has both Camera Link and USB 3.0 interface.
■ Camera Link Interface
Camera Link interface is able to transfer large volumes of data. It can transfer 4
megapixels image with 100 frame/s.
In order to realize such large volume data transfer, the camera uses Camera Link
"Full Configuration Deca Mode" which is an expanded version of Camera Link "Full
Configuration". It enables to transfer maximum 85 MHz x 10 Taps (8 bit) image data
to computer as fast as 100 frame/s.
In order to use this interface, a Camera Link interface board which supports "Full
Configuration Deca Mode" is required.
■ USB 3.0 Interface
USB 3.0 interface is able to transfer 4 megapixels image with 30 frame/s. It is
versatile interface which is suitable to use when fast data transfer is not required.
This interface does not require a Camera Link interface board. It transfers image with
moderate transfer speed.
•
Do not connect Camera Link and USB 3.0 interface simultaneously.
•
When a connection interface is changed from Camera Link to USB 3.0, and vice versa, the
application software must be closed and the camera must be turned off.
(8) Camera readout modes
The camera has two scan speed in Normal area mode, and two readout direction in
Light sheet mode.
