We designed and built a homemade computed tomography imaging spectrometer (CTIS) of 250 × 250 p i x e l s of spatial resolution and 2 nm spectral resolution. The optical design considers a CTIS optical array coupled to a digital reflex camera. We re

This work presents an automated acquisition system for microbolometer array. The solution is based on the case scenario where microbolometer array parameters has to be determined automatically (from an unknown device), avoiding the detector damage ha

We calculate equations to obtain the exact and third-order design of thick lenses free from spherical and coma aberrations at two points, at the edge and center of the lens, considering the shape factor and the conic constants. We obtained analytical

This work reports the development of arrays of infrared sensors (microbolometers) using a hydrogenated polymorphous silicon&ndash
germanium alloy (pm-SixGe1-x:H). Basically, polymorphous semiconductors consist of an amorphous semiconductor matri

Urinary albumin excretion remains the key biomarker to detect renal complications in type 2 diabetes. As diabetes epidemy increases, particularly in low-income countries, efficient and low-cost methods to measure urinary albumin are needed. In this p

During 2016, breast cancer was the second cause of death among women within ages of 24–30. This makes mandatory to find reliable strategies that support physicians and medical services for early diagnosis of such disease. Currently, mammography is

In this paper, we present an analysis of the performance of Raman spectroscopy, combined with feed-forward neural networks (FFNN), for the estimation of concentration percentages of glucose, sucrose, and fructose in water solutions. Indeed, we analys
