Abstract: Images of two-dimensional chromatograms or other sample arrays are formed on a scanning instrument that utilizes a line of illumination light that sweeps the length of the array either by moving across the array or by the array moving relative to the light, in either case scanning the entire two-dimensional array with a unidirectional pass of the moving component. The use of a CCD equipped with time delay integration allows the instrument to form an enhanced image.

Abstract: An imaging section is secured to a casing, and an object is supported on an object support section, which is located within the casing. The object support section is moved within the casing in order for an imaging distance between the imaging section and the object, which has been supported on the object support section, to be altered. Excitation light is irradiated to the object, which has been supported on the object support section, with an excitation light source, which is secured to the object support section. A distribution of illuminances of the excitation light on the object is thus prevented from fluctuating to a fluctuation of the imaging distance.
