A LIDAR system includes an emitter array configured to illuminate a field of view, a detector array configured to image the field of view, and a control circuit. The emitter array includes one or moreemitter elements that are configured to emit respective optical signals responsive to respective emitter control signals. The detector array includes one or more detector elements configured to output respective detection signals responsive to light incident thereon. The control circuit is configured to generate the respective emitter control signals based on the respective detection signals andrespective spatial correlations of the one or more emitter elements and the one or more detector elements with respect to the field of view. Related devices and methods of operation are also discussed. 一种LIDAR系统，包括：发射器阵列，被配置为照明视场；检测器阵列，被配置为对视场进行成像；以及控制电路。发射器阵列包括一个或多个发射器元件，该一个或多个发射器元件被配置为响应于相应发射器控制信号而发射相应光信号。检测器阵列包括一个或多个检测器元件，该一个或多个检测器元件被配置为响应于入射在其上的光而输出相应检测信号。控制电路被配置为基于相应检测信号以及一个或多个发射器元件和一个或多个检测器元件相对于视场的相应空间相关性来生成相应发射器控制信号
