    A database of pixelated images is the current requirement to meet the growing diagnostic needs in the healthcare arena. An innovative fiber pixelated image database is presented, which consists of pixelated images that are synthetically generated and experimentally acquired. Sample space encompasses test patterns of different scales, sizes, and shapes.

    The key challenges in achieving high-quality ICA imaging are its location in the anterior region of the eye and the occurrence of total internal reflection due to refractive index difference between cornea and air. Here, we report an indirect axicon assisted gonioscopy imaging probe with white light illumination.

    Pixelate Removal in an Image Fiber Probe Endoscope Incorporating Comb Structure Removal Methods

      Authors: Anant Shinde and Murukeshan Vadakke Matham.

      Here we reviewed all of the available methods for pixelation removal from images obtained with fiber optic bundle based imaging. We implemented all the methods in our laboratory in MATLAB software and analyzed the performance of these methods for several parameters.

  • Targeted illumination and tracking using optical fiber probe for optogenetics application

    Authors: Anant Shinde, Sandeep Menon Perinchery and Murukeshan Vadakke Matham.

    We have developed a fiber optics based probe system incorporating a spatial light modulator (SLM) and an imaging fiber bundle for selective illumination on the targeted particle. The proposed methodology and developed probe have good significance and expected to find potential applications areas such as optogenetics, cell signaling studies, and lab on a chip systems.

  • Variable resolution imaging fiber probe using digital spatial light modulator

    International Conference on Optical and Photonic Engineering  April 14,  2015.

    Authors: Anant Shinde, Sandeep Menon Perinchery and Murukeshan Vadakke Matham.

    The paper introduces the variation in the contrast by varying the number of illuminated fiberlets which effectively implies variation in the effective pinhole size. This approach has enabled the probe to act as variable resolution imaging unit that can be controlled and varied from a wide-field to a confocal.

  • Synthetic fiber pixelated image database

      SPIE Photonics Europe May 2, 2014

      Authors: ANANT SHINDE and Murukeshan Vadakke Matham.

      We are developing a database of fiber pixelated images. Fiber pixelation is particular kind of noise observed with images obtained with fiber optic imaging probe. We are creating a database of images which will serve as a reference to researcher working on depixelation of these images. This is the first part of the database - the simulated images.
