Optical microscopy techniques based on structured illumination and single-pixel detection
In this Thesis, we explore single-pixel microscopy to design and develop proof-of-principle experiments where the single-pixel detection strategy outperforms conventional optical array detection in wide-field microscopy. The ability of the single-pixel detection strategy to generate a spatially reso...

| Sumario: | In this Thesis, we explore single-pixel microscopy to design and develop proof-of-principle experiments where the single-pixel detection strategy outperforms conventional optical array detection in wide-field microscopy. The ability of the single-pixel detection strategy to generate a spatially resolved image of an object hidden by arbitrary scattering media has been recently demonstrated. Strikingly, a sensor without spatial resolution is able to retrieve a high-resolution image of a sample hidden by a turbid media, a problem that cannot be solved with conventional cameras equipped with millions of pixels. Taking advantage of the simplicity of single-pixel collection systems we have developed an optical design for microscopy that allows dual operation, that is, the simultaneous image in transmission and reflection of the same area of the sample, without the need for calibration. In addition, the analogue to Fourier ptychography microscopy but using imaging techniques with single-pixel detection has been developed. |
