c. elegans worm seen under 5 different forms of microscopy

Description: This c.elegans pharynx is seen through brightfield, darkfield, phase contrast, polarized light, and fluorescence microscopy. All of the images are then overlayed and merged into a final image.

eye and face under near infrared light

Description: Here you see the picture of an eye as seen under near infrared light. The brown eye is seen as light in color as it reflects the near infrared (800-1200 nanometers). A blue eye would appear darker as it is more transparent to those wavelengths

Monte Carlo Modeling of Polarized Light Propagation in Tissue_ Towards Noninvasive Glucose Monitoring in Diabetics

Description: A Monte Carlo model for polarized light propagation in birefringent, optically active, multiply scattering media is developed in an effort to accurately represent the propagation of polarized light in biological tissue. The model employs the Jones N-matrix formalism in order to combine both linear birefringence and optical activity into a single effect that can be applied to photons as they propagate between scattering events. Polyacrylamide phantoms with strain-induced birefringence, sucrose-induced optical activity, and polystyrene microspheres as scattering particles were used for experimental validation. Measurements were made using a Stokes polarimeter that detected scattered light in different geometries, and compared to the results of Monte Carlo simulations run with similar parameters. The results show close agreement between the experimental measurements and Monte Carlo calculations for phantoms exhibiting turbidity and birefringence, as well as for phantoms exhibiting turbidity, birefringence, and optical activity. Other scattering-independent polarization properties can be incorporated into the developed Jones N-matrix formalism, allowing for quantification of the polarization effects via an accurate polarization-sensitive Monte Carlo model.

Laser spot removal

Description: using near infrared lasers that pulse quickly, stains are broken up to be reabsorbed into the skin. The flashes are normally invisible to the naked eye but are made visible because videocameras are sensitive to near infrared light.

3-dimentional OCT imaging of the human finger

Description: Adjacent 2D subsurface OCT images can be combined into a high-resolution 3D image set, as demonstrated here. We present a 3D composite image of the human finger, illustrating OCT’s ability to resolve the stratum corneum, epidermis, and superficial dermis in-vivo. The tubular light-coloured structures in the superficial layer are sweat ducts, known from histology to possess spiral geometry, as confirmed in this OCT reconstruction.
