A method of simultaneously measuring the thickness, group index of refraction, and top and bottom surface profiles of a sample, includes the steps of locating the sample between a surface of a transparent optical flat and a parallel reflective surface such that the respective optical distances between any two of the surface of the optical flat, the top surface of the sample, the bottom surface of the sample, and the reflective surface are distinct and in a known relative optical distance relationship, the distance between the surface of the transparent optical flat and the parallel reflective surface being known. A low-coherent light interferometer operating in an autocorrelation configuration is employed to measure the distance between the optical flat surface and the top surface of the sample, the optical thickness of the sample, and the distance between the bottom surface of the sample and the reflective surface at a plurality of locations over the sample, employing the known relative optical distance relationships. Top and bottom surface profiles and a thickness profile of the sample are generated from the measured distances and the known distance between the surface of the transparent optical flat and the parallel reflective surface. An group index of refraction profile is generated from the measured optical thickness and bottom surface profiles.

Apparatus for measuring the surface profile of a sample, includes a fixture for locating a surface of a transparent optical flat relative to a surface of a sample; a low-coherence light interferometer having an optical probe coupled to an XY scanning frame for scanning the surface of the sample through the transparent optical flat to produce interferometric data signals representing the distances between the optical flat surface and the surface of the sample; and a computer system responsive to the interferometric data signals for generating a surface profile of the sample using a best fit to a plane.

A photographic printer and a method of printing in which the printer is interfaced with a defect detection or scanning system is adapted to inspect photographic paper for defects as it is consumed by the printer. In the system and method of the present invention, when a defect is detected, the printer is enabled to either skip over the defect area or to reprint the affected image. With respect to the defect, when detected, the present invention provides either for the utilization of a defect marker, such as a hole punch, which provides a physical mark on the paper in close vicinity of the defect or an electronic device capable of transmitting the precise location of the defect to the printing section. The hole or electronic signal is recognized by the printer, to enable it to either skip the defective frames or reprint the images.

A method of determining defects in OLED devices having a plurality of pixels, each with its own emissive layer, which are capable of being excited by input light to produce an output color light response, including illuminating one or more OLED devices or a portion of an OLED device with light in a predetermined portion of the spectrum so that the pixel emissive layers are excited to produce an output color response for each pixel, capturing an image of the output light produced by the excited pixels and converting such captured light into a digital image; and determining device pixel size, shape, location, and emitted light intensity from the digital image and comparing such size, shape, location, and emitted light intensity with predetermined acceptable size, shape, location, and emitted light intensity ranges to determine whether there is a defect in the OLED device(s).

The present invention relates to an automatic print inspection method in which photographic prints are scanned to obtain digitized images. The scanned digitized image of the photographic print is compared to digital image data which represents the original captured image. The resulting digital correction data indicates whether or not there are defects in the print media or faults in the printer process, including the digitizing steps. Signal processing transformations may be used to decide how to separate media defects from processing faults and how to correct for the latter. The method of the present invention can be used as a final quality check so that any defective prints can be rejected and remade before orders go out to a customer.

A method for maintaining a peel location and for peeling a layer of media from a surface in a thermal printer. An optical probe, that includes a light source and a photodetector, transmits light from the optical probe toward a first web. The web reflects a portion of the transmitted light onto the photodetector, which then outputs an electrical signal which is compared with a preselected signal level and the difference between them provides an indication as to how much adjustment the peel location requires. Adjusting the peel location may comprise changing environmental characteristics of the first web or the second web (surface) or adjusting a tension of the first or second web. The difference between the measured electrical signal levels is related to a physical distance of the first web from the desired peel location.

An electromechanical system and a printer for maintaining a peel location of media impressed on a receiving substrate. A mounted optical probe has at least one light source and one or more photodetectors for detecting reflected portions of the light emitted or transmitted from the light source. The photodetector indicates to the system controller a distance of the media for controlling a peel location via an electrical signal. A comparator compares the electrical signal with a predetermined electrical signal reference to determine if the media is desirably positioned. The predetermined electrical reference signal corresponds to the desired peel location. The comparator compares the signal levels and outputs a correction signal used in a negative feedback loop for adjusting a velocity of a motor that drives a take-up roller for the media.
