    摘要： Device and method for detecting reactive luminescent nano- or micro-particles embedded in a composite comprising a polymeric matrix with carbon-black or sulphur-black particles, or embedded in a sulphur-dyed substrate or surface, comprising: an infrared or ultraviolet illuminator (101) for illuminating the luminescent particles; a near-infrared photodiode sensor (102) for capturing a near-infrared response of the illuminated luminescent particles; a dark chamber for placing over the substrate or surface, inside which the illuminator and photodiode sensor are mounted; a logarithm amplifier for amplifying and linearizing a response signal captured by the photodiode sensor; an electronic data processor configured for detecting the reactive luminescent particles, by carrying out the steps of: illuminating the substrate or surface with the illuminator (101); acquiring the amplified linearized signal captured by the photodiode sensor; detecting the presence of luminescent particles in the composite or substrate or surface from the linearized decay of the acquired signal.

    摘要： In a sample observation device 1, an image capturing unit 5 includes an area image sensor 21 that performs image capturing by the rolling shutter method in which a start of an exposure period T of each of pixel columns 25 in a pixel region 22 is shifted by a predetermined time, and a generation unit 8 sets one pixel column 25 of the pixel columns 25 as a reference pixel column 25R, and combines a data portion D corresponding to an exposure position P of the reference pixel column 25R in exposure positions P of pixel columns 25 of one frame and the data portion D corresponding to an exposure position P of the reference pixel column 25R in exposure positions P of pixel columns 25 of other frames continuous to the one frame, thereby generating two-dimensional image data Gt corresponding to the exposure position P of the reference pixel column 25R in the one frame.
