Handheld image intensifiers increase the intensity of available light to provide imaging in poorly lit situations. They are widely used by emergency responders in nighttime surveillance, search and rescue, and covert operations. Image intensifiers may assist with navigation of terrain in darkness and recognition of objects and people that may not be seen by the unaided eye. In March 2014, the System Assessment and Validation for Emergency Responders (SAVER) Program conducted an operationally oriented assessment of handheld image intensifiers.
