    摘要: The disclosure discloses a phase delay extraction and compensation method in a PGC phase demodulation technology. The sinusoidal phase modulation interference signal is converted into a digital interference signal by an analog-to-digital converter after amplification and filtering, and the digital interference signal is subjected to orthogonal downmixing of first-order, second-order, and fourth-order harmonics simultaneously to obtain three pairs of orthogonal harmonic amplitude signals. The three pairs of orthogonal harmonic amplitude signals are used to extract phase delay, and the result is used to calculate the corresponding phase delay correction coefficients, and the phase delay correction coefficient are multiplied by the corresponding absolute harmonic amplitude signal equal to the sum of the absolute value of the orthogonal harmonic amplitude signals to obtain a new harmonic amplitude signal that is not affected by the phase delay, then the phase to be measured is obtained through the arc tangent operation.

    摘要: An absolute distance measurement apparatus and method using laser interferometric wavelength leverage includes a light source system, a wavelength-leverage laser interferometric system and an interference signal processing and controlling system. The light source system outputs a orthogonally linearly polarized beam with the wavelength λ1 and the wavelength λ2. The orthogonally linearly polarized beam projects onto the wavelength-leverage laser interferometric system to form the interference beam. The interference beam projects onto the interference signal processing and controlling system. In the wavelength-leverage laser interferometric system, the synthetic wavelength and the single wavelength as well as the measured absolute distance and the moving displacement of the cube-corner prism in the reference arm form a wavelength-leverage absolute distance measurement relationship.

    摘要: The invention discloses an environmentally-friendly pasty discharge agent for textile printing and a method for preparing the environmentally-friendly pasty discharge agent. The environmentally-friendly pasty discharge agent for textile printing is formed by the following raw materials according to part by weight: decamethylcyclopentasiloxane: 30-60 parts; thiourea dioxide: 40-70 parts; surfactant: 1-3 parts; and glycerol: 3-6 parts. Decamethylcyclopentasiloxane is put into a ball mill, a surfactant is added into the ball mill to make the decamethylcyclopentasiloxane dispersed or dissolved uniformly and then stirred uniformly, and then thiourea dioxide is added into the ball mill and ground together for 1-3 hours. In the invention, the special liquid compound decamethylcyclopentasiloxane does not chemically react with the thiourea dioxide; in addition, it isolates the thiourea dioxide from outside water and air, thus increasing the stability of the thiourea dioxide. The discharge effect is excellent, the defects of low dissolvability, poor dispersion uniformity in the discharge paste, poor net permeability and insufficient discharge effect of the common thiourea dioxide as the discharge agent are overcome, and there is no influence on the touch of the discharged and printed textiles.

    摘要: The present disclosure provides a weaving method of a weft-backed jacquard fabric with color shading effects and belongs to the technical field of weaving methods. In a single-warp and double-weft structure with a weft yarn arrangement ratio of Wefts A and Wefts B of 2:1, by designing two groups of face weaves and backing weaves and corresponding backed points and using a shaded strengthening method, two color shading effects of color shading of the Wefts A and mixed color shading of the Wefts A and the Wefts B of the fabric are achieved. A maximum number of shaded weaves is [R/N(6R−2J2−J1−3)+2], and a grade number of shaded color is less than or equal to the maximum number of the shaded weaves. The designed fabric meets the covering requirements and can be mass produced.

    摘要: The disclosure discloses a differential sinusoidal phase modulation laser interferometric nanometer displacement measuring apparatus and method. The beam output from the single-frequency laser is converted into a 45° linearly polarized beam after passing through the polarizer, then projected onto two sets of sinusoidal phase modulation interferometers consisting of the beam splitter, the electro-optic phase modulator, the half wave plate, three pyramid prisms, two polarization beam splitters, thereby forming measurement and reference interference signals which are received by two photodetectors. A high-frequency sinusoidal voltage signal is applied to the electro-optic phase modulator placed in the common reference arm of the two interferometers, thereby modulating the interference signal into a high-frequency AC signal. By detecting the difference between the phase change amounts of the two interference signals when the measured object moves, the measured displacement can be obtained.
