技術說明

一種結構光照明數位全像之方法，包括：(a) 提供一結構光產生單元與二值化亂數編碼單元，以產生編碼的結構光圖紋；(b) 取樣至少二張具相位移圖紋，並合成為單一張帶有編碼的結構光圖紋；(c)形成單一張數位全像片，並進行該單一張數位全像之波前重建；(d)藉由一壓縮感測方法以復原至少二張具相位移圖紋的物體光波；以及(e)進行重疊頻譜分離之重建方法，以獲得具有不同的高頻與低頻帶通頻譜涵蓋範圍之影像。 [0010] In this invention, a method of structured illumination digital holography is provided, and the method comprises: (a) providing a structured illumination generating unit and a binary random number encoding unit to generate a structured illumination pattern; (b) based-on at least two sheets of binary random number encoding patterns of said structured illumination pattern, sampling at least two sheets of patterns with phase shift to be synthesized as a single sheet of structured illumination pattern to be encoded; (c) interfering an encoded structured object wave with a reference wave to form a single sheet of digital hologram, and wavefront reconstructing said single sheet of digital hologram; (d) binary random number decoding said single sheet of digital hologram to extract object wave with corresponding original phase shift pattern, and performing an image processing approach to recover object wave with at least two sheets of phase shift patterns to obtain an image covering bandpass spectrum with different high frequency and low frequency; and (e) reconstructing separation of overlap spectrum of said object wave with at least two sheets of phase shift patterns.
