20110121948 | Security Screening - An RF screening apparatus comprising a scanning chamber and an RF inspection device or reader, the chamber having chamber walls which are substantially reflective to radiation at a frequency of operation. The chamber walls or at least a portion of the chamber walls may be visually transparent. This enables visual inspection and identification of the occupant and RF interrogation to be performed, substantially simultaneously if desired. RF interrogation signals produced by the reader reflect off the chamber walls, approaching a target tag from an increased number of different angles, thus increasing the chance of a successful read. | 05-26-2011 |
