Patent number: 9638637Abstract: A method and system for using spatially modulated excitation/emission and relative movement between a particle (cell, molecule, aerosol, . . . ) and an excitation/emission pattern are provided. In at least one form, an interference pattern of the excitation light with submicron periodicity perpendicular to the particle flow is used. As the particle moves along the pattern, emission is modulated according to the speed of the particle and the periodicity of the stripe pattern. A single detector, which records the emission over a couple of stripes, can be used. The signal is recorded with a fast detector read-out in order to capture the “blinking” of the particles while they are moving through the excitation pattern. This concept enables light detection with high signal-to-noise ratio and high spatial resolution without the need of expensive and bulky optics.Type: GrantFiled: September 2, 2014Date of Patent: May 2, 2017Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Michael Bassler, Peter Kiesel, Oliver Schmidt, Noble M.

Patent number: 9638642Abstract: An apparatus and a method for optically scanning a surface of an object under an adverse external condition to which optical components are subjected, such as cameras and lighting sources sensitive to soiling, make use of a first imaging sensor unit having its optical components subjected to the adverse external condition, and being configured for generating reflection intensity image data associated with a target surface. A second imaging sensor unit having its optical components substantially not subjected to the adverse external condition, is configured for generating reflection intensity image data associated with a reference surface. Correction data are calculated from a comparison between the reflected intensity image data associated with the target and reference surfaces, which correction data are then applied to the reflected intensity image data associated with the target surface to generate corrected intensity image data compensating for the adverse external condition.Type: GrantFiled: November 28, 2014Date of Patent: May 2, 2017Assignee: CENTRE DE RECHERCE INDUSTRIELLE DU QUEBECInventor: Jean-Pierre Couturier
