Abstract:
According to one aspect, the invention relates to an angular optical filtering element (E i ) optimised for angular filtering about a given operating angle of incidence (θ i , φ i ) in a given spectral band. The angular filtering element (E i ) comprises a first nanostructured, band-pass, spectral filter (11 i , 301) and a second nanostructured, band-pass, spectral filter (12 i , 302). Each of the first and second spectral filters comprises, respectively, in said spectral band, a first and a second central filtering wavelength that respectively has a first and second angular dispersion curve defined depending on the angle of incidence (θ inc ) on the optical filtering element (E i ), the curves of angular dispersion being secant about the operating angle of incidence (θ i , φ i ) of the optical filtering element. The invention applies to the production of a selective angular filtering device and to a multidirectional optical detection system.

In the polarization image capturing mode, obtained are first and second polarization images to be generated based on signals representing light that has been transmitted through polarizers that have the polarization transmission axis in respective directions that are parallel to, and intersect with, the first direction while the object is being irradiated with the first illuminating light beam, and third and fourth polarization images to be generated based on signals representing light that has been transmitted through polarizers that have the polarization transmission axis in respective directions that are parallel to, and intersect with, the second direction while the object is being irradiated with the second illuminating light beam. And a depressed region on the surface of the object is detected based on the first and second polarization images that form one pair and/or the third and fourth polarization images that form another pair.
Abstract:
A substrate for controlling the transmission of light therethrough has a light reflecting layer affixed to a light transmitting layer. The light reflecting layer is divided into a plurality of subdivisions arranged in a plurality of rows. Each subdivision has an area, is spaced apart from adjacent subdivisions, and has a different thickness than the light transmitting layer between the subdivisions. By controlling the size, spacing and thickness of the subdivisions and the thickness of the light reflecting layer between the subdivisions it is possible to control the light transmitted through and reflected from the substrate. A method of making the substrate by ablating the light reflecting layer is also disclosed.
