Single Exposure Super Resolved Interferometric Microscopy (SESRIM) has been recently proposed as a way to achieve
one dimensional super resolved imaging in digital holographic microscopy. SESRIM uses Red-Green-Blue (RGB)
multiplexing for illuminating the sample having different propagation angles for each one of the three illumination
wavelengths and it has been experimentally validated considering color (A. Calabuig, V. Mico, J. Garcia, Z. Zalevsky,
and C. Ferreira, “Single-exposure super-resolved interferometric microscopy by red–green–blue multiplexing,” Opt.
Lett. 36, 885-887, 2011) and monochrome (A. Calabuig, J. Garcia, C. Ferreira, Z. Zalevsky, and V. Mico, “Resolution
improvement by single-exposure superresolved interferometric microscopy with a monochrome sensor,” J. Opt. Soc.
Am. A 28, 2346-2358, 2011) digital sensors for holographic recording. In this contribution, we will first review some of
the characteristics of the previously reported SESRIM approaches and second, we will present preliminary results for the
extension of SESRIM to the field of lensless holographic microscopy. Experimental results are reported validating this
new kind of superresolution imaging method named as lensless SESRIM (L-SESRIM).
