Patent number: 8587776Abstract: Techniques are disclosed for sensing a location of laser and/or other optical signals. According to certain embodiments of the invention, an electro-optical assembly can include a detector array coupled to one or more lenses for detecting the signals. Outputs of the photo detectors can be processed using peak detection and/or other techniques to conserve power, help ensure detection, and avoid the need for moving parts.Type: GrantFiled: May 10, 2012Date of Patent: November 19, 2013Assignee: Cubic CorporationInventors: Tony Maryfield, Richard Trissel, David A. Robinson, Robert William Parry
