During microlens array（MLA） photolithography exposure process， the number of photolithography points is considerably large， thus， judgement of the photolithography quality by human eyes with a high-magnification microscope is time

As the probe alignment error influences measurement results of tooth profile deviations of arc cylindrical worms （ZC worm） on the gear measuring center， a probe alignment error correction method should be established. Based on the

Aiming at the multidimensional， extensive range， and precision positioning requirements regarding micromanipulation and micro-assembly tasks， two degree-of-freedom （DOF） parallel positioning platforms with large strokes and no cou

To improve the environmental adaptability of a piezoelectric vibration energy harvester， a magnetically-coupled tunable piezoelectric vibration energy harvester （PVEH） is proposed. The coupling action between the active magnet on

Yttrium aluminum garnet （YAG） crystals are widely used for manufacturing solid-state lasers， and ultraprecision grinding is critical for machining hard and brittle material parts， such as YAG crystals. The investigation of microde

To reduce the volume of ships， aircraft， and other engines， oblique pipe welding is used instead of elbow connection， and the end position in the pipeline system plays an important role in the welding alignment. First， the pipe ax

To improve the imaging quality of optical lenses and eliminate the influence of stray light， an antireflective film with an average reflectance of less than 0.1% in the visible wavelength range was designed on a K9 glass substrate

High-quality ghost imaging （GI） at low sampling rate is of great importance for scientific research and practical applications. Therefore， the reconstruction of high-quality images under low sampling rate conditions remains the fo

A method for detecting electrospinning jets using coaxial laser assistance is proposed to address the challenges of small diameter， high speed， and difficult detection of electrospinning jets. Based on the principle of optical wav

Possible errors in baseline length and angle measurements are qualitatively and quantitatively analyzed to reduce errors in the dynamic monitoring of baseline measurements of the dual-antenna InSAR system that affect the baseline

The large field optical telescope is an important equipment for the search of medium-high orbit targets. However， stellar targets also appear in the search images. Thus， the identification and suppression of stellar targets is a n

A detection method integrating visual saliency and group decision making was proposed with the aim of achieving efficient and high-precision detection of hole features in aircraft parts in complex environments. First， an image enh
