EXULUS-HD1 & EXULUS-4K1 Spatial Light Modulators

5.3.3. Operation Mode

The operation mode provides mode selection of both Frame Rate and Phase Stroke, as well as the control setting
of preview image.
Save Picture
Allows the user to save the current preview pattern as .PNG picture format.
Display on SLM
The SLM displays the current preview pattern by clicking this button.
Clear SLM
Clear the displayed pattern on the SLM panel, reset the SLM with black background.
Frame Rate Mode
The standard frame rate offers the standard operation at each gray level with 60 Hz frequency for EXULUS-HD1(/M)
and 24 Hz/30 Hz frequency for EXULUS-4K1(/M). In this mode, only the red channel of a standard RGB color signal
is sent to the SLM panel.
The triple frame rate provides operation with frequency up to 180 Hz (for EXULUS-HD1(/M) only). This is done such
that all three R, G, and B channels are sent to the SLM panel sequentially. With a standard video frame rate of 60
Hz, the actual frame rate at the SLM panel can be boosted to 180Hz.
Phase Stroke Mode
The Standard Stroke provides a total phase stroke of 2π (633 nm).
The Extended Stroke offers a total phase stroke of 4.7π (532 nm). This mode is available with EXULUS-HD1(/M)
only.
