Optical system for inspecting porous substrates

摘要

An automated system for inspecting a porous substrate using a sample, comprising, a delivery device positioned to apply the sample to a target point on the porous substrate along a sample axis; an imaging device and one or more lenses, positioned so that the imaging device and the lens each has a focus axis that is offset from the sample axis, and have a viewing focal point that is substantially the same as the target point; a light source that is offset from the delivery device to illuminate the surface target; and a processor comprising a data acquisition and control system that coordinates timing and automation of the delivery and imaging devices, and determines one or more characteristics of the porous substrate.

1. An automated system for inspecting a porous substrate using a sample, comprising,
a delivery device fixed along a sample axis to apply a sample to a target point on a porous substrate, wherein the sample axis is perpendicular to the porous substrate; an imaging device and one or more lenses, positioned so that the imaging device and the lens each has a focus axis that is parallel but offset translationally from the sample axis, and the combination of the imaging device and the lens has a viewing focal point that is substantially the same as the target point; a light source that is offset from the delivery device to illuminate the surface target; and a processor comprising a data acquisition and control system that coordinates timing and automation of the delivery and imaging devices, and determines one or more characteristics of the porous substrate.
