Abstract

A portable thermal imaging system includes a portable housing configured to be carried by a user, a bolometer sensor assembly supported by the housing and including an array of thermal sensor elements and at least one plasmonic lens, a memory including program instructions, and a processor operably connected to the memory and to the sensor, and configured to execute the program instructions to obtain signals from each of a selected set of thermal sensor elements of the array of thermal sensor elements, assign each of the obtained signals with a respective color data associated with a temperature of a sensed object, and render the color data.
