Infrared imaging device having a shutter
First Claim
1. A system comprising:
- an infrared imaging module comprising;
an infrared sensor assembly having infrared sensors and adapted to capture image frames;
a housing substantially enclosing the infrared sensor assembly and having at least one conductive trace providing an electrical connection disposed on and extending along at least a portion of an exterior surface of the housing; and
a shutter assembly external to and coupled to the housing, the shutter assembly comprising;
a paddle adapted to selectively block external infrared radiation from reaching the infrared sensors,an actuator adapted to selectively move the paddle in response to a control signal to block external infrared radiation from reaching the infrared sensors, andan electrical contact adapted to interface with the conductive trace on the exterior surface of the housing to receive the control signal while the shutter assembly is coupled to the housing.

Abstract
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.
