Abstract
Disclosed are pharmaceutical dosage unit manufacturing process control apparatus and methods. These can include acquiring a plurality of multi-pixel images of a flow of pharmaceutical dosage units at different wavelengths along an axis that is perpendicular to a direction of the flow of pharmaceutical dosage units, processing the images acquired in the step of acquiring, and providing an indication about the flow of pharmaceutical dosage units based on the step of processing.

1-20. (canceled)
A two-dimensional imaging optical instrument for acquiring images of a two-dimensional sample area, comprising:
- a two-dimensional spatial detector having detector elements aligned along a first axis and a second axis,
- a two-dimensional variable filter having filter characteristics that vary in at least one dimension, and being located in an optical path between the two-dimensional sample area and the two-dimensional spatial detector, and
- wherein the instrument defines the optical path as a two-dimensional optical path that simultaneously conveys radiation from different positions in the sample area to different detector elements through portions of the spatial detector having different ones of the filter characteristics.
An optical method, comprising:
- substantially simultaneously filtering a plurality of radiation beam portions from different positions in a sample area with different filter characteristics, and
- substantially simultaneously detecting the plurality of radiation beam portions with different parts of a spatial detector after filtering the radiation beam portions in the step of filtering.
