A Compact Raster Lensless Microscope Based on a Microdisplay [PDF]
Sensors, 2021 Lensless microscopy requires the simplest possible configuration, as it uses only a light source, the sample and an image sensor. The smallest practical microscope is demonstrated here.

Scatter-plate microscope for lensless microscopy with diffraction limited resolution. [PDF]
Sci Rep, 2017 AbstractScattering media have always been looked upon as an obstacle in imaging. Various methods, ranging from holography to phase compensation as well as to correlation techniques, have been proposed to cope with this obstacle. We, on the other hand, have a different understanding about the role of the diffusing media.

Femtosecond digital lensless holographic microscopy to image biological samples [PDF]
Optics Letters, 2013 The use of femtosecond laser radiation in digital lensless holographic microscopy (DLHM) to image biological samples is presented. A mode-locked Ti:Sa laser that emits ultrashort pulses of 12 fs intensity FWHM, with 800 nm mean wavelength, at 75 MHz repetition rate is used as a light source.

Diffractive digital lensless holographic microscopy with fine spectral tuning [PDF]
Optics Letters, 2013 We experimentally demonstrate an all-diffractive optical setup for digital lensless holographic microscopy with easy wavelength line selection and micrometric resolution. In the proposed system, an ultrashort laser pulse is focused with a diffractive lens (DL) onto a pinhole of diameter close to its central wavelength to achieve a highly spatially ...
