Abstract
Object detection systems are provided herein. An example system includes an enclosure formed by a sidewall to define an interaction volume, at least one light source for illuminating the interaction volume with a light, at least one light sensor that senses disturbances in light intensity due to scattering, reflection, or absorption of the light by objects within the interaction volume, and a controller that is configured to detect an object or object behavior within interaction volume based on the disturbances in the light intensity.
Claims28
An object detection system, comprising:
- an enclosure formed by a sidewall to define an interaction volume;
- at least one light source for illuminating the interaction volume with a light;
- at least one light sensor that senses disturbances in light intensity due to scattering, reflection, or absorption of the light by objects within the interaction volume;
- and
- a controller that is configured to detect an object or object behavior within interaction volume based on the disturbances in the light intensity.

An object detection system, comprising
- a light source comprising a linear array of light emitting devices;
- a light sensor comprising at least one linear array of light sensors, wherein at least one of the light sensors is masked so as to receive less light than non-masked ones of the light sensors in order to reduce a current through the array;
- an interaction volume defined by a space between the light source and the light sensor array, wherein the space between the light source and the light sensor array allows for uniform light intensity throughout the interaction volume;
- and
- wherein the light sensor array senses disturbances in the light intensity indicative of a presence of an object in the interaction volume.
