Abstract

Various techniques are disclosed for providing a device attachment configured to releasably attach to and provide infrared imaging functionality to mobile phones or other portable electronic devices. For example, a device attachment may include a housing with a tub on a rear surface thereof shaped to at least partially receive a user device, an infrared sensor assembly disposed within the housing and configured to capture thermal infrared image data, and a processing module communicatively coupled to the infrared sensor assembly and configured to transmit the thermal infrared image data to the user device. Thermal infrared image data may be captured by the infrared sensor assembly and transmitted to the user device by the processing module in response to a request transmitted by an application program or other software/hardware routines running on the user device.

combine the non-thermal image data and the thermal infrared image data to generate combined image data.

7. The imaging device of claim 1, further comprising a supplementary component at least partially disposed within the housing, the supplementary component configured to generate sensor data associated with at least a portion of the scene.

8. The imaging device of claim 7, wherein the supplementary component comprises at least one of a moisture sensor configured to generate moisture level data associated with the portion of the scene or an electrical parameter sensor configured to generate electrical parameter data associated with the portion of the scene.

9. The imaging device of claim 1, further comprising a non-thermal camera module configured to capture first non-thermal image data.

10. The imaging device of claim 9, wherein the processing module is further configured to receive, via the connector, second non-thermal image data from a non-thermal camera module of the mobile user device.

11. The imaging device of claim 9, wherein the processing module is further configured to combine the first non-thermal image data and the thermal infrared image data to generate combined image data, and wherein the information associated with the thermal infrared image data comprises information associated with the combined image data.
