Contents SimulationsPrint page Simulations Simulations allow you to give life to the optical system in order to generate results. This section contains the following topics:Simulations OverviewSimulations allow you to give life to the optical system in order to generate results. Simulation ManagementThis section presents the different modes of simulation computation available in Speos and describes simulation compatibilities.Interactive SimulationThe Interactive Simulation allows you to visualize the behavior of light rays in an optical system. Direct SimulationThe Direct Simulation allows you to propagate a large number of rays from sources to sensors through an optical system. Inverse SimulationThe Inverse Simulation allows you to propagate a large number of rays from a camera or a sensor to the sources through an optical system. Understanding Advanced Simulation SettingsThe following section describes the advanced parameters to set when creating a simulation. LiDARLIDAR is a remote sensing technology using pulsed laser light to collect data and measure the distance to a target. LIDAR sensors are used to develop autonomous driving vehicles. Geometric Rotating LiDAR SimulationThis section introduces Rotating LiDAR's principles and describes how to create a Geometric Rotating LiDAR simulation. Light ExpertThe Light Expert is a tool that allows you to specify what ray path to display in the 3D view.Propagation ErrorsThe following chapter helps you understand how to visualize and manage potential propagation errors in your optical system. « Creating a Speos PatternSimulations Overview »
