Filter Noise

An ultra-high-speed and high-accuracy charge-coupled device (CCD) laser displacement sensor is used to track and measure the ultrasonic vibration in real time. A series of Matlab programs are developed to filter noise from original data. The ultrasonic vibration frequency and period are evaluated and the ultrasonic amplitude is measured within accuracy ±0.1 μm. Effect of the ultrasonic power on the ultrasonic amplitude is also studied.

In order to improve precision, outdated measurement method, complicated structure and weak anti-jam ability in liquid level measurement, a set of liquid level system was designed with the core of high-precision laser displacement sensor. The system adopted non-contact laser trigonometric survey method and powerful virtual instrument techniques. It could conduct online and real-time measurement to infinitesimal displacement on liquid level with high speed and precision. Through measurement experiment, its accuracy and practical applicability is verified.

Time Position

A real-time position detection system is developed for measuring heavy ions with low fluence and energy of several hundred MeV, which are generated from an azimuthally varying field (AVF) cyclotron accelerator. We investigate the photoluminescence of α-Al2O3 single crystals implanted with Eu (Al2O3:Eu), which is used in the detection system. The Al2O3:Eu scintillators with a fluence of 3.0 × 1016 cm−2 are annealed at 500–900°C. The annealing conditions required for the Al2O3:Eu scintillators to obtain the maximum luminescence are 0.5 h at 600°C. The scintillator is placed on the AVF cyclotron target stage under atmospheric pressure and is irradiated by 260-MeV Ne. An inverted confocal microscope with a ×10 objective lens is positioned behind the Al2O3:Eu scintillator, and the luminescent images during ion irradiation are obtained by a position-sensitive camera unit with a 512 × 512 pixel electron multiplying charge-coupled device. The images indicate that our online measurement system has a sufficient spatial resolution, since the luminous diameter induced by irradiation with 190 ions /s is almost the same as that of the microbeam.

The inspection of sheet strips post high-speed punching mainly relies on the manual off-line inspection with basic inspection equipment or CCD equipment. Such inspections cannot reflect the real-time conformity of strip machining, and in severe cases, lead to rejects in batches, causing a tremendous waste in production. Now that the application of charge-coupled device (CCD) technology in product inspection is relatively mature, it would be a very good thought to adopt the CCD technology to realize real-time online inspection of conformity of the high-speed punched strips.
