Abstract: A newly designed micro-lens array, being used integrative transmitting and receiving combined with continuous scanning, was proposed and demonstrated. Based on the typical Kepler telescope structure with a field lens, the micro-lens arrays with three-piece style, conducts the selection of receiving field of view (FOV) and the synchronous deflection of transmitting light with large FOV by laterally slight displacement between the two contiguous micro-lenses. In order to avoid the loss and crosstalk of light energy, the visual magnification of telescope is constrained to be 1 which makes the apertures of micro-elements in incident and emitting ports keep consistent. With the ZEMAX software, the entire optical model is mainly composed of transmitting and receiving parts that are designed independently and joined together later. The micro-lens array's central wavelength is 1 064 nm, with ±1.06° instantaneous FOV and ±10° scanning FOV, the size of each micro-element is 1 mm×1 mm.In addition, the bilateral scanning can be realized with only one moving element.The designed system is characterized by the advantages including compact size, large scanning range and high sensitivity.
