Quantitative imaging for optical field via a single-pixel detector

Complex-amplitude Fourier single-pixel imaging via coherent structured illumination

“…Recently, several attempts were made to acquire the complex-amplitude information of objects by using SPI techniques, such as single-pixel diffractive imaging, [27][28][29] single-pixel wavefront sensing, [30][31][32] singlepixel ptychography, [33] single-pixel digital holography, [34][35][36][37][38][39] and single-pixel phase imaging based on common-path interferometry. [40][41][42][43][44][45][46] Benefiting from the advantages of SPI, the complex-amplitude single-pixel imaging is becoming a promising imaging modality in the fields of optical microscopy, [40] optical metrology, [45] and biomedical science. [39] In this paper, we present a novel complex-amplitude Fourier single-pixel imaging (CFSI) method by combining coherent structured illumination [29,35,40,42,45] and common-path interference [40][41][42][43][44][45][46] with a Fourier basis scan.…”

Complex-amplitude Fourier single-pixel imaging via coherent structured illumination

“…Single-pixel imaging (SPI), as an emerging imaging technique characterized by using structured illumination and a single-pixel detector, has the potential to overcome the challenge [11]. Thus, several attempts were made to achieve the complex amplitude information of objects by using SPI techniques, such as singlepixel diffractive imaging [12][13][14], single-pixel wavefront sensing [15][16][17], single-pixel ptychography [18], singlepixel digital holography [19][20][21][22][23][24], and single-pixel phase imaging based on common-path interferometry [25][26][27][28][29][30].…”

“…In this letter, we present a novel complex-amplitude Fourier single-pixel imaging (CFSI) method by combining coherent structured illumination [14,20,25,27,29] and common-path interference [25][26][27][28][29][30] with Fourier basis scan [31][32][33][34]. Different from previous CFSI methods [22,27,28] that use the digital micromirror device based on the super-pixel method for complex-amplitude modulation, we employ a phase-only spatial light modulator to generate both the structured light and the reference light to form the coherent structured illumination.…”
