B.1 Introduction
This topic is only valid for the FS variant of the projector.
Introduction
In the FS-series projectors, one of the night vision modes is achieved by feeding the projector with two
separate inputs, one with content for visible light (VL), and the other with content for the infrared (IR). Outside
the projector, these two inputs may have the same content, achieved by a splitter or by cloning the output in
the graphics adapter on the image generator (IG).
This topic describe some usage scenarios and the setup to use, to achieve the best performance. It should
serve as a guide for how to set up the system or give guidance if the exact user case is not described here.
B.2 How infrared is displayed
How infrared is displayed
In night vision mode with 2 separate inputs, the projector displays the two inputs alternating every other frame.
The output is displayed a double speed of the inputs, i. e. at 120Hz in case of 60Hz input. The DMD is
illuminated with visible RGB light every other frame, while the IR “light” is illuminating the DMD all the time.
The display device (DMD) itself do not know whether it is displaying IR or VL. And this is causing problems
when the actual image content is not carrying all 3 color components (full RGB). As an example, only the red
color component is active on the input. The DMD is attempting to display this as an RGB image even if it is
illuminated with IR. The result is that the DMD is active only approximately one third of the frame, thereby
“wasting” a lot of the IR output power.
In Pulse release 2.1 and onwards, there is an option to create a Color Component mapping per connector
input. This gives the flexibility on individual connector to connect DMD “colors” to input color channel.
B.3 Default setup
Default setup
In the default setup, the RGB components of the DMD fetches the content from the RGB component of the
inputs. This mode of operation is best suited for when the VS and IR inputs both carries a full RGB image and
specially the IR channel has full black/white content if displayed on a regular monitor. This is not a clone or
spitted image even if the content in the example below indicates the same image on both inputs.
