Optical methods represent the most promising techniques to perform non-invasive glucose detection. Glucose concentration in the aqueous humor closely mimics glucose levels in the blood and therefore non-invasive optical measurement of glucose can be performed by an optical beam crossing the eye anterior chamber. We propose a polarimetric method that exploits the Brewster-reflection of circularly polarized light on the lens of the eye. After reflection, the resulting linearly polarized light is subject to rotation by the glucose in the aqueous humor and thus carries the concentration information. A preliminary experimental setup, using glucose samples in a beaker, was realized and investigated.

This paper describes the optical system Svision including the attachment to PC’s monitor and software for preparation and demonstration of stereoscopic images. This software-hardware complex provides possibility to demonstrate 3D stereoscopic objects on the kinescope screen of usual PC’s monitor, such objects are interactively controlled by user. Advantages of system Svision over analogues are the following: spectators do not need individual hardware for viewing, there are no need in rework of computer, production of attachments is simple and does not require unique techniques. The complex is used for processing and display of data measured by means of scanning-probe microscope for analysis of complicated 3D objects and also for precision measurement schemes.

Infrared thermography is used to reveal the establishment of Erwinia amylovora harpin-induced hypersensitive response (HR) in Nicotiana sylvestris leaves. We observed a decrease in temperature (1-2°C) in the harpin infiltrated zone, correlated with an increase in stomatal opening, strongly suggesting that the temperature decrease is due to higher transpiration rate. IRT experiments were conducted in a laboratory environment and could be widely applied for genotype screening and monitoring drug effects.
