Lensless fluorescence imaging with height calculation [PDF]
Journal of Biomedical Optics, 2014 Lensless fluorescence imaging (LFI) is the imaging of fluorescence from cells or microspheres using an image sensor with no external lenses or filters. The simplicity of the hardware makes it well suited to replace fluorescence microscopes and flow cytometers in lab-on-a-chip applications, but the images captured by LFI are highly dependent on the ...

Lensless imaging for point-of-care testing. [PDF]
Annu Int Conf IEEE Eng Med Biol Soc, 2009 We show a platform that merges a microfluidic chip with lensless imaging for CD4(+) T-lymphocyte counting at resource-limited settings. To capture CD4(+) T lymphocytes, anti-CD4 antibody was immobilized on a microfluidic chip. The captured cells were detected by a charge coupled device (CCD) sensor using lensless shadow imaging techniques.

Coded Illumination for Improved Lensless Imaging
IEEE Transactions on Computational Imaging, 2023 Mask-based lensless cameras can be flat, thin, and light-weight, which makes them suitable for novel designs of computational imaging systems with large surface areas and arbitrary shapes. Despite recent progress in lensless cameras, the quality of images recovered from the lensless cameras is often poor due to the ill-conditioning of the underlying ...

Lensless photography with only an image sensor
Applied Optics, 2017 Photography usually requires optics in conjunction with a recording device (an image sensor). Eliminating the optics could lead to new form factors for cameras. Here, we report a simple demonstration of imaging using a bare CMOS sensor that utilizes computation.
