Abstract: A scanning densitometer is disclosed for obtaining color density measurements from colored samples, such as color bars and the like. The scanning densitometer includes a densitometer head (100) and a densitometer head transport system (101) having transport bars (102, 103). A sample sheet is positioned under the transport bars (102, 103) and the self-propelled head (100) moves over the sheet along the bars (102, 103) toward an end limit stop (105). During a return movement from the end limit stop (105) to a docking end housing (110), color measurement data is obtained. Upon docking at the docking end housing (110), an optical communications interface is provided so that data from the densitometer head (100) can be transmitted to a host computer.

Abstract: A spectrophotometer apparatus (200) is adapted to provide spectral reflectance measurements of object samples. The apparatus (200) comprises a source light (254) and a reflection optics assembly (264, 268). Signals representative of reflected light are analyzed and data provided to an operator representative of the spectral response characteristics of the object sample (252). The apparatus (200) further comprises a side sensor (276) having a fixed spectral response characteristic for compensating the reflectance measurements in accordance with the light intensity emanating from the lamp. For purposes of calibration, a series of time-sequenced measurements are made of a reference sample. Utilizing these measurements, the apparatus (200) provides computations of compensation coefficients for each spectral segment. The compensation coefficients are utilized, with the side sensor measurements, to provide normalization of the reflectance measurements for each segment and for each measurement within the timed sequence. For each segment, a scale factor is then determined. The scale factors, compensation coefficients and side sensor measurements are employed to compensate actual reflectance measurements, with further compensation provided by a determination of temperature coefficients.

Abstract: A colour detection and/or recognition apparatus comprises a twin row array (16) of detector elements, each element being arranged to produce an electrical signal on detection of a given colour. The two rows (21, 22) each comprise a plurality of groups of detector elements, with the elements in each group of at least one of the arrays being sensitive to a respective different colour, with corresponding elements in the two rows being sensitive to different colours, and with the four elements of adjacent corresponding pairs of elements in the two rows being sensitive to at least three different colours. The electrical signals are processed to provide a determination of the detection of colour or the recognition of a colour. The two rows of detector elements, typically photosensitive sites in CCD arrays, may be formed closely adjacent one another on the same semiconductor substrate, together with CCD shift registers (23, 24) along the outide edges of the two rows. A line buffer delay circuit (25) may be provided for the outputs of one of the rows.

Abstract: An apparatus for determining displacement of an object, comprises a light source (10) which propagates a polychromatic light signal along a path to a detector (22), the detector (22) being capable of detecting the intensity of incident radiation at a plurality of different wavelengths, and a radiation modulation means (16) mechanically coupled to said object for movement therewith, displacement of the object being arranged to cause displacement of the radiation modulating means (16) in said path such as to vary the distributed spectral content of the light reaching the detector (22). In one embodiment the radiation modulation means comprises a filter (16) which attenuates the intensity of transmitted wavelengths to different degrees and which is mechanically coupled to said object such that movement of the object displaces the filter (16) so as to vary the extent to which the filter intercepts the radiation signal propagated by said light source (10).
