navigate.model.waveforms.remote_focus_ramp_triangular(sample_rate=100000, exposure_time=0.2, sweep_time=0.24, remote_focus_delay=0.005, camera_delay=0.001, amplitude=1, offset=0, ramp_type='Rising')

Returns a numpy array with a triangular ramp typically used for remote focusing

The waveform starts at offset and stays there for the delay period, then rises linearly to 2x amplitude (amplitude here refers to 1/2 peak-to-peak).

Switching from a left to right remote focus ramp is possible by exchanging the rise and fall periods.

Parameters:

• sample_rate (Integer) – Unit - Hz

• exposure_time (Float) – Unit - Seconds

• sweep_time (Float) – Unit - Seconds

• remote_focus_delay (Float) – Unit - Seconds

• camera_delay (Float) – Unit - Seconds

• amplitude (Float) – Unit - Volts

• offset (Float) – Unit - Volts

• ramp_type (String) –

Returns:

waveform

Return type:

np.array
