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.
Claims26
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 the interaction volume based on the disturbances in the light intensity, wherein the controller is further configured to time stamp signals received from the at least one light sensor and wherein the objects are insects, further wherein the controller is further configured to detect and record a sequence, the sequence comprising a first time at which an insect is not present in the interaction volume, a second time at which an insect is present in the interaction volume, and a third time at which the insect is not present in the interaction volume, wherein detecting the sequence indicates a count of an insect in the interaction volume.

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 at least one linear array of light sensors, wherein the space between the light source and the at least one linear array of light sensors allows for uniform light intensity throughout the interaction volume;
- and
- wherein the at least one linear array of light sensors senses disturbances in the light intensity indicative of a presence of an object in the interaction volume.
