11-2 LIGHTSHEET READOUT MODE

Lightsheet Readout Mode is a unique feature of CMOS image sensor which provides improved control

over the rolling shutter mechanism.

By finely synchronizing the camera readout with the illumination scan, scattered light is rejected allowing

images of higher signal to noise ratios to be acquired.

The detail information of Lightsheet Readout Mode is published on our website.

11-2-1 READOUT DIRECTION

The camera reads out from the top to the bottom line (Figure 11-13) or from the bottom to the top line

(Figure 11-14) in Lightsheet Readout Mode.

11-2-2 ABOUT READOUT AT LIGHTSHEET READOUT MODE

(1) Readout methods

This mode can set Normal readout and Sub-array readout.

Binning readout mode is not supported at Lightsheet Readout Mode.

The size and the position of the sub-array readout can be configured according to the table below.

Note

•

Minimum settable step of the size and position on the table is in only the case that the camera is

used with DCAM-API.

(2) Camera operation modes

This mode can use; Free running mode, Edge trigger mode (External trigger mode), and Start

trigger mode.
