    Abstract: Disclosed is a method for determining the reflectance of an object, the method including a step of solving an equation having several unknowns, the equation being obtained from formed images, the reflectance of the object and the illumination of the external light source being two unknowns of the equation. The step of solving the equation includes: calculating solution points of the equation, interpolating the calculated points by way of an interpolation function, and using at least one of the following approximations to solve the equation: a first approximation according to which each image is derived from the emission of a separate light flash, a second approximation according to which the interpolation function determines the stability points of the equation.

    Abstract: Increasing signal to noise ratio in optical spectra obtained by spectrophotometers. An interferometer introduces interference effects into a source light beam. A dual beam configuration splits the source beam having the interference effects into a reference beam and a sample beam. The reference beam interacts with a reference substance and is detected by a reference detector. The sample beam interacts with a sample substance and is detected by a sample detector. An optical spectra of the sample is based on the difference between the detected reference beam and the detected sample beam.
