Class Description

class atomiq.components.optoelectronics.lightmodulator.Shutter(switch, invert=False, opening_time=0, closing_time=0, *args, **kwargs)

Bases: Component, Switchable

Component to switch light on or off depending on a logical signal. This could be a mechanical shutter or a binary only amplitude modulator (e.g. AOM, EOM, Pockels cell etc.). It requires a class:Switchable switch that operates the shutter

Parameters:

• switch (Switchable) -- Switch that operates the shutter, e.g. TTL

• invert (TBool) -- invert the logic of on and off

• opening_time (TFloat) -- Time in s it takes from the arrival of the TTL until the shutter is fully opened (default 0)

• closing_time (TFloat) -- Time in s it takes from the arrival of the TTL until the shutter is completely closed (default 0). Note that if closing_time is > 0 the shutter is already closing before the time at which the off() method is called

A Switchable has one ore more channel(s) that can be switched on or off
