The Study Of The Multi-spectrum Device Base Of Semipermeable Half The Mirror

Multi-spectral imaging in modem nondestructive testing technology is of great significance, may to the object appearance quality and internal components of measuring and analyzing and processing of agricultural products, has been used in a variety of the look and feel of the internal quality detection in.Taking a semipermeable half trans multi-spectral imaging device for the object of study, based on geometric optical imaging theory research, analyzes a semipermeable half trans multi-spectrum in designing the existing problems, and each optical components such as lens face, lens aperture in the design such as light as poor, distortion and dispersion, etc. By ZEMAX optical design software, through software calculation and optimization method, designed as difference is small, distortion, dispersion low multi-spectral imaging system.Paper application software MATLAB experiments of image acquisition are analyzed, through the design of imaging spectral device and CCD sensor took several groups of fruit, use of MATLAB software photos of image processing toolbox, analyzes the different spectrums of image, through RYGB four-color image contrast analysis, better able region fruit appearance quality.
