Active illumination single-pixel camera based on compressive sensing

Abstract: We present an optical imaging system based on compressive sensing (CS) along with its principal mathematical aspects. Although CS is undergoing significant advances and empowering many discussions and applications throughout various fields, this article focuses on the analysis of a single-pixel camera. This work was the core for the development of a single-pixel camera approach based on active illumination. Therefore, the active illumination concept is described along with the experimental results, which were … Show more

“…The programmed patterns are used as generalized measurement modes where the object information is expressed. The same principle enables retrieval of the spatial information of an object with the use of a single-pixel detector in ghost [16,17] and compressive imaging [18,19]. In the latter case, the development of data collection strategies based on compressive sampling allows image compression to be performed at the sensing stage [20].…”

“…In that case, we could state that the current would vary with different compressive codes as the amount of light hitting the photodiode area would also vary with the compressive codes. This variation imposed by the compressive codes would then allow us to reconstruct the images being acquired [9]. In order to explain how the images are reconstructed based on the histograms, consider the example shown in Table 1.…”

“…This allowed us to have an insight of the level of noise present in the corresponding measurements. Based on previous work [9], we can state it is possible to reconstruct images of similar quality in a compressive imaging manner when the amplitude of the noise is below 20% of the maximum amplitude of the signal without noise (SNR = 14.54 dB). Therefore, it is possible to infer from Table 2 that a histogram built using a number of measurements above 5000 shall address the stated desired conditions.…”
