— Looking for a self-consistent formula for the DC P(I) characteristics of a laser diode (LD), able also to predict the threshold current, a model has been developed for the general electric and optical DC characteristics of a forward-biased LD.
– This paper presents an automatic alignment procedure for a 4-Source Photometric Stereo technique to reconstruct the depth map in the Scanning Electron Microscopy. PS, based on the so-called reflectance map, used several images of a surface to estimate the surface depth at each image point. Lambertian reflectivity function is the simplest one. In the SEM… (More)
