Patent number: 11363954Abstract: A device and method for fluorescent imaging may include an imaging unit including a fluorescent camera with an optical detector that is configured to acquire a fluorescent image of a fluorescing sample, the image including raw pixel values. A user interface may display an image formed from display image pixels derived from the raw image pixels. A distance sensor may measure a distance to the fluorescing sample. A distance between the optical detector and fluorescing sample may be determined from the measured distance. A processing unit may obtain a gain value, match the determined distance to a distance value associated a respective gain range, and impose limits of the gain values range onto the gain value, to determine a limited gain value. The limited gain value may be applied to the raw image pixels, thereby deriving display image pixels.Type: GrantFiled: October 3, 2018Date of Patent: June 21, 2022Assignee: Visionsense LTD.Inventors: Nadav Horesh, Alex Chanin, Ofer Braude

Patent number: 6091843Abstract: A method of analyzing particles for chemical or biological species. Spectral images of the particles are acquired. Targets are identified in the images and are classified according to morphology type and spectrum type. Each target is assigned a value of an extensive property. A descriptor vector is formed, each element of the descriptor vector being the sum of the extensive property values for one target class. The descriptor vector is transformed to a vector of mass concentrations of chemical species of interest, or of number concentrations of biological species of interest, using a relationship determined in a calibration procedure. In the calibration procedure, spectral images of calibration samples of known composition are acquired, and empirical morphology types and spectrum types are inferred from the spectral images. Targets are identified in the spectral images, classified according to morphology type and spectrum type, and assigned values of an extensive property.Type: GrantFiled: September 3, 1998Date of Patent: July 18, 2000Assignee: Greenvision Systems Ltd.Inventors: Nadav Horesh, Danny S.
