    • A method and apparatus of interrogating an addressable array unit, which includes a substrate, a light reflecting layer on a front side of the substrate, and a plurality of features on a front side of the array. The method may include, for each of multiple features, illuminating the feature simultaneously with reflected and non-reflected interrogating light. A light emitted from respective features is detected. Either or both, constructive interference of interrogating light at the features, or constructive interference of light emitted from the features, can be obtained to allow lowering of light power from the source, enhanced signal, or reduced noise, or combinations of the foregoing. High depth discrimination may also be obtained without the need for a confocal detection system with conventional pinhole.

    • A test system for measuring a rotary load comprises a stepper motor drives a gear box that is mounted at one end of a frame. A torque sensor provides a measurement signal transmission. The gear box's output shaft is connected to one of the torque sensor's stubs by means of a universal joint coupling. On the other side of the torque sensor a second universal joint coupling connects the sensor to a stainless steel shaft. A low friction flange bearing is used to provide support for the shaft. An angle encoder is disposed on the end of the shaft distal to the gear box. The gear box's output shaft, the torque sensor's cylindrical shaft hubs and associated couplings are arranged such that they are directly aligned with the shaft. The test system has been designed to take automated torque and angle readings from a shaft capable of rotary motion. The measurement arm configuration with the stepper motor directly connects the torque and angle sensors to a PC based data acquisition card for acquisition and processing of data. The system operates according to a method used to make a true torque measurement of a rotary actuated shaft or wheel in a process where a first data set is acquired with the system unloaded as the shaft or wheel is actuated through the defined travel path. The actuation force applied by the stepper motor is accurately controlled through a computer interface. Torque data is measured at each angular step as the wheel is actuated in a first direction. Torque data is then measured at each angular step as the wheel is actuated in the opposite direction. A load is then placed on the test system. With the load on the system, torque data is acquired/measured at each angular step through the defined travel path. Torque data is then measured at each angular step as the wheel is actuated in the opposite direction through the defined travel path. Ultimately, the true torque, i.e. torque less the effects of friction and the system baseline mechanical profile, is determined by adjusting measurement data to virtually eliminate these two effects.
