摘要： A system for detecting a surface type of an object includes a driver component, a driver component, and a plurality of photosensitive elements. The surface of the object is divided along a first direction into a plurality of areas, and the driver component sequentially moves one of the plurality of areas to a detection position. The light source component faces the detection position and provides light of a plurality of spectra that are different from one another to illuminate the detection position. The photosensitive elements face different sections of the area at the detection position, to capture detection images of different sections of the area located at the detection position under the light of each of the spectra. One photosensitive axis of the photosensitive elements is parallel to the normal line while another photosensitive axis of the photosensitive elements is between the normal line and the first direction.

摘要： The true impact of preharvest factors such as crop load, canopy position, cultivar and rootstock on peach internal quality can be determined using multivariate visible light radiation (Vis) and near infrared spectroscopy (NIRS) prediction models to non-destructively assess peach internal quality (dry matter content, DMC; soluble solids concentration, SSC) and maturity (index of absorbance difference, IAD). A novel crop load×fruit developmental stage protocol allowed accurate multivariate Vis-NIRS-based prediction models development for three major yellow fleshed peach typologies (fully red over-colored, early-ripening bi-colored and late-ripening bi-colored) to non-destructively assess peach internal quality (DMC and SSC) and maturity (IAD) with a single scan during fruit growth and development in the field. The impact of preharvest factors such as crop load and canopy position on peach quality and maturity can be evaluated across a variety of peach cultivars using this novel technology.

摘要： A method for determining the thickness of a plurality of coating layers. The method comprises the steps of performing a calibration analysis on calibration data to determine initial values and search limits of optical parameters of the plurality of coating layers, irradiating the plurality of layers with a pulse of THz radiation in the range from 0.01 THz to 10 THz, detecting the reflected radiation to produce a sample response derived from the reflected radiation, producing a synthesized waveform using the optical parameters and predetermined initial thicknesses of the layers, varying the thicknesses and the optical parameters within the search limits to minimize the error measured between the sample response and the synthesized waveform, and outputting the thicknesses of the layers.

摘要： A system for biomolecule identification by terahertz sensing, an asymmetric triple split-rectangular (ATSR) metamaterial biosensor, and a method for biomolecule identification by terahertz sensing are presented. The asymmetric triple split-rectangular (ATSR) metamaterial biosensor includes three gap areas which highly confine an electric field. The biosensor includes an E-shaped structure facing an inverted E-shaped structure with gaps between the respective legs. Each leg has a specially designed extension on either side which increases the electric field. A terahertz laser interrogates an analyte upon the metamaterial structure with a plurality of frequencies. The amplitude difference is estimated by an amplitude difference referencing technique. The amplitude difference is matched to a database record to identify the biomolecule analyte. The asymmetric triple split-rectangular (ATSR) metamaterial biosensor in combination with the amplitude difference referencing technique detects the type of biomolecule with a high degree of accuracy and requires only small analyte samples with sub-micron thicknesses.
