Digital airborne cameras play a significant role for aerial Photogrammetry development from analog to full-digital age. Because of the gap between digital sensor performance and Photogrammetry request, digital airborne also becomes the bottleneck of full-digital approach. In this paper, we present a design of twice-imaging airborne camera system with distributed sensors based on film camera, an...

This paper presents a new analysis method for locating the focus and estimating the size of the focus of the backscatter light of a Lidar system. The formula for calculating the uncertainty of the location of the focus of backscatter light of a Lidar system is given, and the estimation of the size of the focus is also presented. This calculation coincides with the analysis result of ZEMAX softw...

Introduction The aim of the present study was to determine burn intensity in retinal laser photocoagulation based on laser parameters; wavelength, power, beam size and pulse duration, using Optical Coherence Tomography (OCT), fundus camera, physical eye model and computer simulation in a clinical study. Materials and Methods Participants were 10 adult patients between 50-80 years with prolife...

— It is shown that the theory of aplanatic two-mirror telescopes developed by Karl Schwarzschild in 1905 leads to the unified description both the prefocal and the postfocal systems. The class of surfaces in the ZEMAX optical program has been properly extended to ascertain the image quality in exact Schwarzschild aplanats. A comparison of Schwarzschild aplanats with approximate Ritchey–Chrétien...
