Abstract
An optical detector configured to detect a presence and a location of modulated light including a wide FOV detector having one or more photodiode and a narrow FOV detector having a narrow-FOV photodiode. The wide FOV detector at least partially surrounds the narrow FOV detector and provides a wide FOV, and the narrow FOV detector provides a narrow FOV. The optical detector can be implemented in a single optical detector system having a single optical path to a single focal plane.
Claims27
An optical detection system, comprising:
- a lens having a focal plane;
- a wide field of view (FOV) detector configured to detect incident light at the focal plane corresponding to a wide FOV, wherein the wide FOV detector includes a window;
- and
- a narrow FOV detector configured to detect incident light at the focal plane corresponding to a narrow FOV, wherein the narrow FOV detector is positioned to detect light incident to the window.
An optical detector configured to detect a presence and a location of modulated light, the optical detector comprising:
- a wide FOV detector including one or more wide-FOV photodiodes;
- and
- a narrow FOV detector including a narrow-FOV photodiode,
- wherein the narrow-FOV photodiode provides a second FOV and the one or more wide-FOV photodiodes provide a first FOV, the first FOV and second FOV received through a single optical path to a detection plane.
A method of detecting a presence and a location of a modulated light source, the method comprising:
- focusing light corresponding to a narrow FOV and light corresponding to a wide FOV onto a detector comprising a narrow FOV detector and a wide FOV detector;
- detecting light corresponding to the narrow FOV at the narrow FOV detector and detecting light corresponding to the wide FOV at the wide FOV detector;
- measuring one or more optical characteristics of the light detected at the narrow FOV detector and light detected at the wide FOV detector;
- and
- generating an output corresponding with light detected by the narrow FOV detector and the wide FOV detector.
