Creating an *.OPTSequence File for a Physical Camera Sensor
The following page presents you the workflow on how to create an *.OPTSequence file to be used in a Physical Camera sensor.
To create an *.OPTSequence file:
-
Create a Speos Light Box Export
containing all the geometries related to the lens system (lenses, opto-mechanics, etc.)
You can also do an OpticStudio Import to define the geometries of the Light Box.
-
Define the Axis System of the Light Box so that the optical axis of the lens system follows
the Z axis.
The origin of the axis system must be located with a small offset from the first geometry face. For more details, refer to Understanding the Physical Camera Parameters.
-
Define if the Light Box is black-boxed or not.
Note: A black-boxed Light Box will not be supported with a Light Expert Analysis.
- Compute the Light Box Export.
-
Define the Axis System of the Light Box so that the optical axis of the lens system follows
the Z axis.
-
Create an Irradiance
sensor:
- Position the Irradiance sensor in the scene considering the lens system defined in the Light Box, which is usually placed in front of it.
- Select the Planar integration type.
-
Select Sequence as Layer type and define
sequences per Faces.
This will allow to generate the *.OPTSequence file to be used later in the Physical Camera sensor.
- Create a Physical Camera in which you will add the Light Box containing the lens system, and the Irradiance sensor (with Layer defined by Sequences and Sequences defined per Faces).
- Compute the Physical Camera.
-
Create a Direct or an Inverse simulation:
- Make sure the Dispersion is activated.
-
Add the Physical Camera.
Note: Light Expert is not compatible when the Physical Camera uses a black-boxed Light Box.
-
Add geometries and sources.
The ability of the *.OPTSequence file to be generated to solve optical paths highly depends on the source setup you will add here. For more information, refer to Understanding the Physical Camera Parameters.
Important: The *.OPTSequence file depends on the simulation type. An *OPTSequence file generated with a Direct simulation can only be used as input in a Direct simulation. The same rule goes for the Inverse simulation. - Run the simulation.
