At present the cell array lens is usually cylinder or hemispheroid whose fill-factor (the ratio of light area and total area ) can achieve about 90.7%, so we need higher fill-factor arrays sometimes such as in the compound eye simulation optical system.

A micro hotplate array was made by incorporating several micro hotplates into a single chip as an integrated sensor array.

集成的阵列式的微传感器是当今传感器发展的一个方向，例如广谱气体传感器，该种传感器需要把多个微热板集成在同一个芯片，形成微热板阵列的器件形式。

This implies that as you get closer to the array, each module has to radiate into a larger included angle, so the splay angles between modules must increaseas you move from the top to the bottom of the array.

这意味著当你离线阵列越近，其每一个扬声器模组的辐射角度应该越大，所以阵列中从上至下，箱体之间的间隔角度也应该是逐渐增大的。

The conventional adaptive beamforming techniques like MMSE and NLMS beamformers can not provide a satisfied performance in some situations such as antenna array overloading and a small angle difference between a desired signal and an interferer.

This thesis mainly discuss following issues, Theory and simple expressions for array covariance matrixes are derived when angular spread functions are symmetric distribution functions, i. e. the Uniform distribution, the Gauss distribution, the Laplace distribution and the Von Mises distribution, and a non-symmetric distribution function, i. e. the Gamma distribution. And the relation between the effective signal subspace and the array number, or and the nominal angle of the distributed source, the angular spread, the distributed functions, and the Signal-to-Noise Ratio is gained. The dimension of the effective signal subspace increases with increment of the array number. And it is more obvious to the non-symmetric distribution. The dimension of the effective signal subspace decreases with increment of the nominal angle. And the distributed source is equal to a point source as θ=π/2. The dimension of the effective signal subspace increases with increment of the angular spread.

本论文针对阵列信号处理中广泛存在的分布源现象，主要讨论了以下问题：推导了角度分布函数分别为对称的均匀分布、高斯分布、拉普拉斯分布、Von Mises分布和非对称的伽马分布时，分布源阵列接收信号协方差阵的严格模型和简化模型，得到了单个分布源的有效信号子空间随阵元数、分布源中心角、分布角、角度分布函数和信噪比的变化规律：随着阵元数的增加，对所有角度分布函数的有效信号子空间维数也随着增加，且非对称分布函数的有效信号子空间充满整个空间的可能性更大；随着分布源中心角逐步增加，有效信号子空间维数逐步减小，当θ=π/2时，等价于点源情形；随着分布源分布角逐渐加大，有效信号子空间维数也随之增加，直到有效信号子空间充满整个空间；随着信噪比的增加，有效信号子空间维数有一定程度的减少。

In making stacks with such laser chips we found that the array output power is lower than the sum of the output power of individual lasers and the reduced ratio increases with the increase of the number of individual lasers.
