摘要： A colorimeter capable of calibrating color monitors, whether having cathode ray tube or liquid crystal (LCD) displays, is provided by a photometric array of photodetector (38) and optical filter (50) pairs. The filters (50) include long-pass, edge filters which cover overlapping regions at the upper end of the visible spectrum and a filter which covers the entire visible spectrum. The outputs of the photodetectors (38) are digitally synthesized to provide a response which mimics the response established by the Commission Internationale de l'Eclairage (CIE) xyz (bar) functions almost perfectly. The response which is mimicked may be represented by the CIE color matching functions. The pairs (38, 50) and the associated components are mounted on a printed circuit board (32) captured in a clamshell housing (12, 14) and having an array of apertures (20) which define angularly constrained fields of view of a surface from which the light, to be colormetrically analyzed, emanates.

摘要： A spectrophotometer system adapted to be inserted into the side of a compact computer or other computerized devices, as an accessory card which may interface with the computer in accordance with the standards of the Personal Computer Memory Card International Association (PCMCIA) is provided. On this card and disposed along an edge thereof is a spectrophotometer (24). The spectrophotometer optics (26) are connected to a fiber optic cable (32) at the end of which is a light receiving and transmitting opening exposed to the object under test. The card may carry a lamp (36) which is coupled to the fiber optic from the spectrophotometer so as to illuminate the object under test. The card has all of the electronics necessary for spectral measurements, including a microprocessor.
