Retinal laser photocoagulation is an established and successful treatment for a variety of retinal diseases. While being a valuable treatment modality, laser photocoagulation shows the drawback of employing high energy lasers which are capable of phy

Optical pen-size reflectometer for monitoring of early dental erosion in native and polished enamels. Journal of biomedical optics, 18(11), p. 117009. SPIE International Society for Optical Engineering 10.1117/1.JBO.18.11.117009
Application of the specular reflection intensity was previously reported for the quantification of early dental erosion. Further development of the technique and assembly of the miniaturized pen-size instrument are described. The optical system was a

Due to a frequent consumption of acidic food and beverages, the prevalence of dental erosion increases worldwide. In an initial erosion stage, the hard dental tissue is softened due to acidic demineralization. As erosion progresses, a gradual tissue

We developed an FPGA-based engine for Fourier-domain OCT that performs real-time signal processing based on Non- Uniform Fast Fourier Transform (NUFFT). The basic NUFFT algorithm is discussed and compared with cubic-spline interpolation regarding eff

Effects of enamel abrasion, salivary pellicle, and measurement angle on the optical assessment of dental erosion. Journal of biomedical optics, 17(9), p. 97009. Bellingham, Wash.: SPIE International Society for Optical Engineering 10.1117/1.JBO.17.9.097009
The present study assessed the effects of abrasion, salivary proteins, and measurement angle on the quantification of early dental erosion by the analysis of reflection intensities from enamel. Enamel from 184 caries-free human molars was used for in
