Abstract: An illumination head (1) for machine vision has an annular support (2) with first, second, third, and fourth illumination sections (3, 4, 5, and 6). The third section (5) has three sets of LEDs (12, 13, 14) arranged in a pattern so that each set illuminates at approximately the same angle. Each set is driven in succession so that a series of three monochrome images at the same angle are captured. These are superimposed by an image processor to provide a color image, although the camera is monochrome. More information can be obtained in such a color image and the high resolution and robustness of monochrome cameras is availed of.

Abstract: The matrix biochip sensing system of this invention uses a low-cost LED (light emit diode) matrix as the light source for the sensing system. The matrix biochip sensing system comprises an LED matrix light source, a biochip clamping member, an optical information filter module, an optical lens array, an optical sensor and a signal processing and control module. The light spots of the LED matrix is turned on in sequence, such that the fluorescent spots of the biochip that are respectively corresponding to the light spots of the laser diodes matrix may be actuated in the same sequence. Fluorescent spots so actuated are focused to a single optical sensor through an optical lens. At each sensing cycle of the optical sensor, only one fluorescent spot may be actuated. The output of the optical sensor in combination of the time axis may be processed by the signal processing and control module to obtain the genetic signals of the biochip.

Abstract: An apparatus for optical inspection of containers (12) includes a light source (14) having at least one light emitting diode (16) with a light emitting die surface (18). Lenses and/or mirrors (20, 43) focus the light emitting die surface onto a selected portion of a container, and a light sensor (24) receives an image of the selected portion of the container illuminated by the light source. An information processor (28) is coupled to the light sensor for detecting commercial variations in the illuminated portion of the container as a function of the image received at the sensor. The image can be developed by transmission of the light energy through the selected portion of the container, and/or by reflection and/or refraction of the light energy at the selected portion of the container. The light source may include a single light emitting diode, or a plurality of light emitting diodes having light emitting die surfaces focused onto the container in such a way that the images of the light emitting die surfaces overlap and/or are adjacent to each other at the container.
