When a hydrophilic intraocular lens material is immersed, its volume and mass start increase due to the diffusion of water (or isotonic saline solution) reaching a quasi-equilibrium in a time scale of several hours. Here, we present a combination of

A new Zemax model has been developed, which reliably predicts the light output of scintillator crystal pins for Positron Emission Tomography. Different configurations, including pin shape, surface finish and reflector types are investigated. The simu

Enhanced operation of a coherent infrared differential absorption lidar was demonstrated in case when appropriately selected laser sources were used. Good agreement with experimental data supports the idea that, in the case of reinjecting the weak fr

A new concept is presented realizing controlled deflection of emerging light cone from excited crystal pins in a PET block detector. The new light sharing module consists of special double prism units optically coupled to a continuous light guide. Sl

A new Zemax model has been developed that is capable to predict reliably the light output of scintillator crystal pins of different configurations, i.e. geometry, surface finish and reflector material. Model parameters are measured wavelength depende

LIDARs are powerful devices for remote detection of atmospheric pollution. However calibration of data is difficult as there are no other methods that allow for fast non interfering remote measurement of the integrated concentration. In a unique fiel

A new detection method is presented for detecting the weak optical signal scattered back from a topographic target. The weak signal arriving from a topographic target is amplified by the frequency modulated transmitter laser of the lidar system and t

In the article, an optical method is described to measure the surface roughness on ultrafine machined metal surfaces. The method is capable for measurement of surface roughness without mechanical contact, and without removing the work piece from the

A frequency-shifted local oscillator beam was produced by a rotating radial grating in an infrared heterodyne detector operating with a CO2 laser. Reduction in mixing efficiency due to beam distortion on diffraction from the radial grating was predic
