Sensors Overview

Sensors integrate rays coming from the source to analyze the optical result.

Irradiance Sensor Radiance Sensor Intensity Sensor

Sensors allow to integrate and analyze rays coming from the sources contained in an optical system.

A wide variety of sensors are available to cover different needs and configurations.

The sensors can be used to compute power and analyze how a source is emitting and what is its intensity/emission pattern or to create perspective and viewpoints to see how a system is perceived by an eye, an observer.

Types of Sensors

  • The Radiance Sensor allows you to compute radiance (in watt/sr/m2) or luminance (in candela/m2).
  • The Irradiance Sensor allows you to compute irradiance (in watt/m2) or illuminance (in Lux).
  • The Intensity Sensor allows you to compute radiant intensity (in watt/sr) or luminance intensity (in candela).
  • The 3D Irradiance Sensor allows you to compute irradiance of volume bodies or faces.
  • The Human Eye Sensor allows you to accurately simulate human vision by considering the physiological characteristics of the eye.
  • The Immersive Sensor allows you to observe all the objects surrounding a defined point of view. A point is placed in the scene and the sensor restitutes what is viewed from the scene from this specific point.
  • The 3D Energy Density Sensor allows you to compute the energy density carried out by the light in Lumen/m3 or Watt/m3 which can be useful when working with highly diffusive materials, wanting to track some hot spots or wanting to visualize the rays' distribution inside the volume itself.
  • The Observer Sensor allows you to create an observer point in the scene.
  • The Light Field Sensor allows you to measure the distribution of light hitting a surface and to generate a Light Field file storing light distribution on this selected surface.
  • The Camera Sensor allows you to simulate rays integration as in a real camera.
  • The Physical Camera allows you to create a lens system with its own optimized propagation engine, to be included in a bigger optical system, which improves the convergence when propagating rays and considers ghost images.
  • The LiDAR Sensor allows you to create a LiDAR source and sensor that can be used for LiDAR simulation.
  • The Geometric Rotating LiDAR sensor allows you to perform field of view studies to quickly identify how to optimize your LiDAR system.
  • The Light Expert Group is dedicated to perform a Light Expert analysis for several sensors at the same time.

In Speos

You can manage all the characteristics of the sensors: its size, position, orientation, wavelength sensitivity etc.

To create a sensor you have to define several parameters: (The parameters vary based on the type of sensor.)
