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.
Claims27
An object detection system, comprising:
- 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 objects within the interaction volume;
- 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 object is an insect, wherein the controller is further configured to detect and record a sequence, the sequence comprising a first time at which the insect is not present in the interaction volume, a second time at which the 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 the insect in the interaction volume;
- and wherein the controller is further configured to detect a waveform of light that is resultant from a modulation of the light intensity by a wing beat.

An object detection system, comprising:
- a light source comprising at least one light emitting device;
- at least one light sensor being masked or equipped with a filter so as to receive less background light;
- an interaction volume defined by a space between the light source and the at least one light sensor, wherein the space between the light source and the at least one light sensor allows for uniform light intensity throughout the interaction volume;
- wherein the at least one light sensor senses disturbances in the light intensity indicative of a presence of an object in the interaction volume;
- and
- wherein a controller is configured to detect a waveform of light that is resultant from a modulation of the light intensity by a wing beat.
