BVS CA-GT1-0051BG (5.1 Mpix [2464 x 2064])

Introduction

The sensor uses a global shutter, i.e. light exposure takes place on all pixels in parallel, although subsequent readout is sequential.

Frame rate calculator

Note
The calculator returns the max. frame rate supported by the sensor. Please keep in mind that it will depend on the interface and the used image format if this frame rate can be transferred.

Link speed: 10 Gigabit Ethernet (GigE Vision) with Bytes/s
Frame rate (max): 1/s
Rowtime: 1.94 us

Note
The exposure time step width is limited to the sensor's rowtime and therefore
  • auto exposure with very low exposure times will perform with relatively large increments and
  • exposure mode = TriggerWidth (if available) will perform with a jitter corresponding to the rowtime.

The following trigger modes are available:

Setting (GenICam) Mode / Setting (obsolete "Device Specific") Description
"TriggerSelector = FrameStart"
"TriggerMode = Off" 		Continuous Free running, no external trigger signal needed.
"TriggerSelector = FrameStart"
"TriggerMode = On"
"TriggerSource = Software"
"ExposureMode = Timed"

To trigger one frame execute the TriggerSoftware@i command then. 		OnDemand Image acquisition triggered by command (software trigger).
"TriggerSelector = AcquisitionActive"
"TriggerMode = On"
"TriggerSource = <desired Line>"
"TriggerActivation = LevelLow"
"ExposureMode = Timed" 		OnLowLevel Start an exposure of a frame as long as the trigger input is below the trigger threshold. (No FrameTrigger!)
"TriggerSelector = AcquisitionActive"
"TriggerMode = On"
"TriggerSource = <desired Line>"
"TriggerActivation = LevelHigh"
"ExposureMode = Timed" 		OnHighLevel Start an exposure of a frame as long as the trigger input is above the trigger threshold. (No FrameTrigger!)
"TriggerSelector = FrameStart"
"TriggerMode = On"
"TriggerSource = <desired Line>"
"TriggerActivation = FallingEdge"
"ExposureMode = Timed" 		OnFallingEdge Each falling edge of trigger signal acquires one image.
"TriggerSelector = FrameStart"
"TriggerMode = On"
"TriggerSource = <desired Line>"
"TriggerActivation = RisingEdge"
"ExposureMode = Timed" 		OnRisingEdge Each rising edge of trigger signal acquires one image.
"TriggerSelector = FrameStart"
"TriggerMode = On"
"TriggerSource = <desired Line>"
"TriggerActivation = AnyEdge"
"ExposureMode = Timed" 		OnAnyEdge Start the exposure of a frame when the trigger input level changes from high to low or from low to high.
