Abstract: In a textile color analyzer, a sample of textile is supported on the pad of an elevator mechanism that holds the sample against an instrument head. The head has an opaque housing provided with a chamber having an opening therein. A glass plate is mounted in the head and covers the opening and presses against the textile sample to provide a stable reference plane. The head includes an illuminating fiber optic bundle that directs light substantially perpendicular to the textile sample. A plurality of additional fiber optic bundles are mounted to receive diffuse light reflected from the sample. The elevator includes a pad of translucent polyethylene material that backs up the textile sample and takes on the color of the sample so that there are no adverse effects due to light showing through the sample and reflecting from the plate.

Abstract: A spectrophotometer is operative to measure or analyze the colors of materials such as textiles. A test sample is held by a holder and is illuminated by polychromatic light. Diffuse light reflected from the sample is collected and converted to variable monochromatic light and detected. The system is calibrated by using a secondary white standard calibrated against a primary white standard, by using a black standard to compensate for dark current and internal reflectance from a pressure plate, and by using a mirror to obtain internal wall reflectance used in a correction factor.

Abstract: A charge storage diode array target is provided with a resistive layer over the output side of the target over the diode portions and the area between diodes, with metal contact caps over the resistive layer over the diode portions. The target is operationally aged with input radiation sufficient to produce an output signal current density of at least about 300 nanoamps per square centimeter at a given reverse bias potential, for a period of at least 50 hours. The target thereafter exhibits high beam acceptance and low lag characteristic.
