|Enable||If enabled, Fast Z Image Stack(s) are acquired on GRAB and LOOP acquisitions where #Slices > 1 for frame scanning. This also enables 3D scans for arbitrary line scanning.|
|Scan Type||Specifies whether a sawtooth or stepped Z waveform should be used for Z control.|
|Volumes to Collect||Specifies number of FastZ Image Stacks to scan during each GRAB or LOOP Repeat. For Volume Imaging acquisitions, ScanImage collects a total of #Volumes x #Slices frames for each GRAB or LOOP Repeat.|
If enabled, FastZ motor controller returns to its Home position – the initial axial position when a GRAB or LOOP was initiated – following the GRAB acquisition or each LOOP Repeat. This ensures subsequent acquisitions or Repeats traverse the same axial positions.
|# Slices||Specifies number of slices (i.e. frames) to acquire during each volume period.|
Specifies axial distance traversed between each successive slice (frame) during a volume period in microns
If enabled, axial position at start of image stack acquisition is taken as the center of the stack. Actuator is moved backwards by half the total span implied by #Slices and Step/Slice prior to the start of the stack acquisition.
|Specify Zs||Control only appears when stepped waveform is selected. Allows manually entering desired Z planes with arbitrary spacing to image.|
|Z Series||Control only appears when manual selection of Z planes is enabled. Allows entry of a space-separated or comma-separated list of z planes to image.|
Volume Timing Controls
|Volume Period Adjustment|
Specifies amount by which to reduce length of Z actuator waveform. Value should always be negative.
|Flyback Time (ms)|
Time to allow for Z actuator to travel back from end position of the volume to the start position. This has a slightly different effect between sawtooth and step/settle modes:
|Actuator Lag (ms)|
Specifies the lag in the Z actuator response. This value advances the Z actuator waveform to compensate for the lag.
|# Discard Frames|
Displays the number of flyback frames that will be added to the volume. This is controlled by the flyback time set above.
|Actuator Tuning...||Launches the FastZ Actuator Tuning window.|
