技術說明

【中文】 一種壓縮感知成像方法及系統。此方法包括下列步驟：根據壓縮感知理論，產生以浮點值表示其中多個元素的灰度值的多個灰度遮罩作為感知矩陣；根據各個灰度遮罩中各個元素的灰度值，控制空間調變器調變投射於待測物的電磁波，並偵測通過待測物的電磁波的物理量以獲得多個測量值；以及利用灰度遮罩及使用各個灰度遮罩調變電磁波所獲得的測量值，執行影像重建演算法以重建待測物的影像。 【英文】 A compressed sensing imaging method and a compressed sensing imaging system are provided. In the method, multiple grayscale masks having multiple elements with grayscale values represented by floating-point values are generated as sensing matrices based on a compressed sensing theory. A spatial light modulator (SLM) is controlled to modulate an electromagnetic wave projected on an object under test according to the grayscale value of each element in each grayscale mask, and a physical property of the electromagnetic wave after passing through the object under test is detected to obtain multiple measured values. The grayscale masks and the measured values obtained from the electromagnetic waves modulated by each grayscale mask are implemented to execute an image reconstruction algorithm to reconstruct an image of the object under test.
