This paper proposes a dusty image enhancement algorithm based on the RGB color balance method to address the problem of color difference in low-contrast and low-definition outdoor images in dusty environments. The method mainly in

The fingerprint characteristics of the terahertz absorption spectrum of materials have been widely used in material identification， but the strong absorption of terahertz waves by water vapor in the actual atmospheric environment

X-ray images play an important role in the diagnosis of pneumonia disease， but they are susceptible to noise pollution during imaging， resulting in the imaging features of pneumonia being inconspicuous and an insufficient extracti

To improve the visual effect of infrared and visible image fusion， images from two different sources were decomposed into low-rank images and sparse images with noise removed by latent low-rank representation. Moreover， to obtain

Raspberry has the reputation of being "the third generation of gold fruits." Obtaining accurate data on the planting area of raspberries is of great significance for adjusting the crop planting structure and industrial development

In the power semiconductor market， insulated gate bipolar transistor （IGBT） and silicon carbide metal-oxide-semiconductor field-effect transistors （SiC MOSFETs） have excellent voltage resistance and frequency characteristics， and

To investigate the effect of abrasive agglomeration on the wear behavior of optical glasses during magnetorheological finishing， this study used an environmentally controlled linear reciprocating tribometer to conduct friction and

In large-aperture telescopes， the relative positions of the primary and secondary mirrors must conform to stringent specifications. The secondary-mirror system is frequently designed as an adjustable mechanism with several degrees

To improve the measurement accuracy of the radius of curvature， a high-precision measurement method of a differential confocal radius of curvature based on a five-dimensional （5D） pose monitoring adjustment was proposed. On the ba

A laser linewidth measurement system based on an unbalanced Michelson interferometer achieved using a 3 × 3 coupler and phase signal demodulation is reported in this study. The signal processing section is based on phase signal de

The design goals of a spectropolarimetric system are higher spectropolarimetric resolution， a smaller and lighter system， and static measurement of the full Stokes spectrum. Therefore， the spatially modulated heterodyne interferen

Laser triangulation spot location is usually affected by the skewness of the image spot. To improve the measurement accuracy and surface adaptability of the laser triangulation displacement sensor by analyzing the skewness charact

To calibration the signal-to-noise ratio（SNR）of split-focus plane polarization image sensors， a calibration experiment of the SNR of each channel of a split-focus plane polarization image sensor was designed. The SNR parameters of
