  8. The use of interferometer to detect and analyze laser radiation is well known, but when the intense ratio of the laser radiation to the background natural light radiation is too small, the laser radiation cannot be detected. a novel more sensitive method for detect of wideband weak incident laser in strong background noise is introduced in this paper. the optical unit uses two wedge interferometers and two line array detectors. the incoming light radiation is divided into two beams and through the interferometers

    在被動激光偵察告警中，對微弱脈沖激光信號的探測是一個難點。當探測距離相當遠或視場內接收的背景光輻射很強時，脈沖激光信號到達探測器的能量很小，會淹沒在強大的背景光信號中而探測不到。本論文提出了一種探測微弱脈沖激光信號的方法，可對強烈背景光中的激光威脅信號進行探測和告警，並給出其波長參數。

  10. In chapter 5 we develop a new quantity optics based illumination model by incorporating a self - radiation term of the object in traditional illumination model. our new model is suitable both for ir waveband imaging and for visible waveband imaging. the model successfully simulates the natural radiation phenomena such as the color of iron during the different fused phases

    本文第五章從量子光學的理論出發，提出了一個新的基於量子光學的光照模型，該模型在傳統光照模型的基礎上增加了一項物體自身量子輻射項，可同時適用於紅外波段和可見光波段的成像
