Patent number: 10218921Abstract: An imaging method includes receiving electromagnetic radiation at a focal plane array of a handheld device. The electromagnetic radiation is processed within the handheld device, and visible images are displayed on the handheld device. The displayed visible images are indicative of a scene, and include a designator and a designator identifier when a high frequency laser pulse is in the scene. The designator and designator identifier represent the high frequency pulsed electromagnetic radiation received by the focal plane array when a high frequency pulse is present in the scene.Type: GrantFiled: September 15, 2016Date of Patent: February 26, 2019Assignee: Sensors Unlimited, Inc.Inventors: Henry W.
