    摘要: In one embodiment, the present invention is a method and apparatus for measuring the focus performance of a camera and lens combination. One embodiment of a test target for measuring a focus performance of a camera and lens combination includes a target body, the target body displaying a pattern including: a primary pattern covering a portion of the target body and a secondary pattern superimposed over a portion of the primary pattern, the secondary pattern being aligned along an edge of the target body. The test target also includes a ruler positioned adjacent to the edge of the target body, a ruler positioned adjacent to the edge of the target body, such that the secondary pattern directly abuts a zero line of the ruler.

    摘要: A low-cost and non-invasive method for remote monitoring deformations of a structure (2), which method envisages to couple at least two RFID tags (3) to the structure (2) in its respective points (10a, 10b, 10a-10c), to interrogate at radio frequency the RFID tags (3) so that a resultant electromagnetic field is produced at a certain distance (DINF) from the structure (2), the resultant electromagnetic field ensuing from a combination of the electromagnetic fields produced individually by each RFID tags (3) in response to the interrogation, to measure the resultant electromagnetic field at such a distance (DINF) from the structure (2) for obtaining measurements of the resultant electromagnetic field, and to determine the deformations of the structure (2) as a function of the measurements of the resultant electromagnetic field.
