Abstract:
An inspection system is disclosed. An optical assembly establishes an optical path between a light source and a detector. The optical assembly has a relatively large amount of longitudinal chromatic aberration, so that light at a first wavelength focuses on one region of a substrate in the optical path, while light at a second wavelength simultaneously focuses on another region of the substrate. The system can operate in a calibration mode to determine one or more wavelengths of light corresponding to regions of interest in the substrate and in an imaging mode to image regions of interest in the substrate.
Abstract:
An optical electric field enhancing device is used with a measuring method which includes two-dimensionally scanning a surface in in-plane direction of the surface to detect, from the rear surface side of the device, signal light emitted from each scanning point when excitation light is applied, and obtaining a two-dimensional signal image on the surface based on the detected signal light. The device includes a transparent substrate, a marker pattern directly formed on the transparent substrate and extending in a direction non-parallel to the main scanning direction of the two-dimensional scanning, and fine uneven structures formed on the marker pattern and the transparent substrate where at least the surface is made of a metal film.

Abstract:
An inspection system is configured for use with a conveyer apparatus including carrier bars. Each carrier bar conveys pellet-shaped articles along a predetermined path. The inspection system includes at least one camera unit for sensing a predetermined characteristic of the pellet-shaped articles, a removal unit, and a controller. The removal unit, downstream from the at least one camera unit, removes selected pellet-shaped article(s) from the carrier bar(s) depending on whether the characteristic is sensed by the at least one camera unit. The controller is in communication with the at least one camera unit and the removal unit. The controller provides a signal to the removal unit in accordance with the sensed characteristic. The removal unit includes a rotatable ejection drum having extended vacuum nozzles along its length, equal to the number of articles conveyed in each carrier bar. Each vacuum nozzle selectively removes article(s) from the carrier bar(s) by suction.

The system also comprises an actuator assembly, a backside illumination assembly, a frontside illumination device, a lens and detector assembly and at least one processor to process electrical signals generated by the lens and detector assembly.
Abstract:
This invention is a hand-held spectroscopic food sensor for analyzing the chemical and/or nutritional composition of food which projects a beam of light that serves as a fiducial marker for image analysis to better estimate the size and/or quantity of the food. In an example, this hand-held spectroscopic food sensor can be in wireless communication with a wearable or implanted device which detects eating and the person can be prompted to use the hand-held spectroscopic food sensor when data collected by the wearable or implanted device indicates that the person is eating.
