3D scanning microscopy through scattering surfaces using the optical memory effect
Harish Sasikumar, Gerwin Osnabrugge, Kirsten Gerritsma +2
Wavefront shaping allows light to be focused through scattering objects. However, the wavefront correction found is only valid in a small region called the isoplanatic patch. Here…
Inline calibration of spatial light modulators in nonlinear microscopy
Daniël W. S. Cox, Harish Sasikumar, Ivo M. Vellekoop
We present a method for calibrating the response of a phase-only spatial light modulator in nonlinear microscopy. Our method uses the microscope image itself as calibration measure…
Quality-Quantity Trade-offs in Tests for Management of COVID-19-like Epidemics
Harish Sasikumar, Manoj Varma
There are multiple testing methods to ascertain an infection in an individual and they vary in their performances, cost and delay. Unfortunately, better performing tests are someti…
Tracking-free Determination of Microparticle Motion from Image Variance
Harish Sasikumar, Manoj M. Varma
In this work, we use the standard deviation of image pixel intensity to analyse the speed, direction and surface-interaction of microparticles in fluid. First, we present an analyt…
Detection Limit for Optically Sensing Specific Protein Interactions in Free-solution
Harish Sasikumar, Manoj M. Varma
Optical molecular sensing techniques are often limited by the refractive index change associated with the probed interactions. In this work, we present a closed form analytical mod…
