With the increasing light adaptive time , the length of rhabdom trended to be longer and proximal pigment trended to spread more widely , but the variation was smaller in full bright light and short wave ( blue ) light conditions than that in long wave ( red ) light condition 蓝光照条件下感杆束直径和长度变化与全光照相似,但近端色素的伸展幅度以蓝光下条件最大,红光次之,均大于全(色)光照条件。复眼结构对短波光(蓝光)的敏感性高于长波光(红光) 。
In this paper , the ultrastructures of compound eyes in blue and red light conditions were firstly studied with the transmission electron microscope in macrobrachium nipponense . the changes of ultrastructural features of rhabdom and cells around were well observed , and were compared thoroughly with the features in full bright light and dark conditions . the functions and significances of related cells structures were discussed during the breakdown and rebuilding of the photoreceptor membrane 本文利用透射电镜技术,首次对红、蓝光照条件下日本沼虾复眼结构,重点是小眼感杆束及其周围细胞超微结构变化作了详尽的观察和研究,并与全光照和全暗条件下的结构特征进行全面比较,探讨相关细胞结构在光感受膜的降解和重新合成过程中的作用和意义。
So research in this paper on ommateum contain two points , first researching ommateum like other normal visual system , considering contents including preprocessing of ir images , target image segmentation , feature extraction and target classification ; second researching ommateum ' s special feature 本文就是从这两点展开讨论研究。首先,把复眼作为一般视觉系统看待,从图像的预处理、图像的分割、特征提取以及目标的分类与识别,这一系列的一般视觉处理过程来考虑。
We firstly testified that the manipulative light conditions could n ' t eliminate the circadian change of ultrastructures of compound eyes in m . nipponense . the compound eyes showed corresponding light adaptive features during the diurnal dark adaptation , and showed dark adaptive features to some extent during the nocturnal light adaptation 首次用实验证实人工光照不能消除日本沼虾复眼超微结构的昼夜节律性变化,即在白天的暗适应时仍表现出相应的明适应特征,而在晚间的明适应时则表现出一定程度的暗适应特征。
An ommatidium is composed of cornea , two corneagenous cells , four cone cells , eight retinular cells , rhabdom , distal pigment cells , distal and proximal reflecting pigment cells , in blue , red and in full bright light conditions , compound eyes exhibit obvious characters the disarrangement of microvilli in the rhabdom , the increased number of lamellar bodies , distal and proximal pigment granules covering the crystalline cone and rhabdom to prevent hard light damaging the ommatidia 现将我们的研究结果报道如下:日本沼虾复眼属于反射型重叠像眼,每一小眼由角膜,成角膜细胞( 2个) ,晶锥细胞( 4个) ,小网膜细胞( 8个)及其形成的感杆束和远端色素细胞、远端反光色素细胞、近端反光色素细胞组成。小眼角膜长方形,小眼密度为512个mm ~ 2 。
Image mosaic technique of imitating compound eyes this paper puts forward a registration method based on space coordinate . aiming at multiple frames static scenes , a new image mosaic method imitating compound eyes is presented based on wavelet multi - scale analysis . a new ruler of image mosaic is founded 图像的仿复眼镶嵌整合技术推导了基于空间坐标投影的图像配准算法,针对多幅静态图像提出了仿复眼的基于小波多分辨分析的图像镶嵌整合算法,建立了一种新的图像整合规则;针对具有运动目标的序列图像,提出了基于特征的仿复眼图像镶嵌整合算法。
In our experiment , after light and dark adaptation , the retina of the macrobrachium rosenbergi was respective incubated in high calcium solution , physiological solution and low calcium solution . we studied the effect of calcium concentration on the content and subcellular localization of gq protein a subunit in the photoreceptor cell of macrobrachium rosenbergi on light adaptation and dark adaptation by sds - page technology and imunoelectron microscopy technology . our study results indicated : 一 、 effects of calcium concentration on the soluble gq protein a subunit in the photoreceptor cell of macrobrachium rosenbergi on light adaptation and dark adaptation 而钙离子对gq蛋白亚基活性有无影响还未见报道。我们以光适应和暗适应条件下的罗氏沼虾复眼视网膜为材料,分别用高钙溶液、生理溶液、低钙溶液孵育后,通过sds ? page电泳技术及免疫胶体金电镜技术,研究钙离子浓度对光暗适应时罗氏沼虾感光细胞gq蛋白亚基含量的影响及亚基亚细胞定位的影响。
Aiming at some problems about fly vision applying to imaging guidance , such as , algorithm and realization of motion - detectors array , image mosaic technique of imitating compound eyes , target detection of compound eyes , realization of compound eyes in missile , and so on , the main contents of this paper are as follows : 1 本文针对蝇视觉在成像制导应用中需要解决的问题,如蝇复眼运动检测器阵列的算法及实现、图像的仿复眼镶嵌整合、蝇复眼目标检测机理、蝇仿生复眼的结构及在导弹上的配置等,集中研究了以下几方面内容: 1
We observed the surface structure and inner structure of the compound eyes . and we also studied the change process of the ultrastructure of the compound eyes in different light adaptation . comparative studies on the structure differences of photoreceptor between portunus tritubereulatus and metapenaeusensis were also done 运用电子显微镜技术观察了三疣梭子蟹( portunustritubereulatus )的光感受器的超微结构,对三疣梭子蟹复眼的外部形态、大小、内部超微结构,以及在不同光适应条件下的变化过程进行了研究;并且与刀额新对虾( metapenaeusensis )光感受器的超微结构进行了比较。
