Patent number: 10389953Abstract: A shutter assembly may be provided for an infrared imaging module to selectively block external infrared radiation from reaching infrared sensors of the infrared imaging module. For example, the shutter assembly may comprise a paddle situated external to an optical element (e.g., lens) and adapted to be selectively moved by an actuator to substantially block external infrared radiation from entering the optical element. The shutter assembly may be stacked relative to a housing of the infrared imaging module without excessively increasing the overall profile of the infrared imaging module. A substantially reflective low emissivity interior surface may be provided on the paddle to reflect infrared radiation originating from an infrared sensor assembly of the infrared imaging module back to the infrared sensor assembly.Type: GrantFiled: June 23, 2015Date of Patent: August 20, 2019Assignee: FLIR Systems, Inc.Inventors: Theodore R.

Patent number: 9900526Abstract: Various techniques are provided to compensate for and/or update ineffective (e.g., stale) calibration terms due to calibration drifts in infrared imaging devices. For example, a virtual-shutter non-uniformity correction (NUC) procedure may be initiated to generate NUC terms to correct non-uniformities when appropriate triggering events and/or conditions are detected that may indicate presence of an object or scene to act as a shutter (e.g., a virtual shutter). Scene-based non-uniformity correction (SBNUC) may be performed during image capturing operations of the infrared imaging device, for example, when a virtual-shutter scene is not available. Further, snapshots of calibration data (e.g., NUC terms) produced during the virtual-shutter NUC procedure, the SBNUC process, and/or other NUC process may be taken.Type: GrantFiled: June 25, 2015Date of Patent: February 20, 2018Assignee: FLIR Systems, Inc.Inventors: Joseph Kostrzewa, Vu L.
