SENSOR TO INSPECT DOCUMENTS OF VALUE Russian patent published in 2015 - IPC G07D7/12 

FIELD: measurement equipment.

SUBSTANCE: invention relates to a sensor for inspection of a document of value, which moves relative to the sensor. The technical result consists in provision of inspection at low speeds of movement and wide range of attenuation time values. The sensor comprises a lighting device to illuminate a document of value by exciting light, and several detectors for continuous detection of luminescent radiation, which emits the document of value illuminated with exciting light in different areas of detection, which are located with displacement relative to each other along the direction of sensor movement. The first of detectors is made to generate the first signal of luminescence of the first area of detection, which in the measurement plane partially matches the illuminated section, and the second of detectors is made to generate the second signal of luminescence of the previous detection area, which, when considered along the movement direction, is located in front of the first area of detection in the measurement plane.

EFFECT: sensor provides for inspection of luminescence attenuation time on the basis of luminescence signals of several detectors.
