Reflective ISO12233:2000 Enhanced 7000-Line Resolution Chart TC-R7K
TC-R7K is an improved ISO 12233:2000 chart for electronic-camera resolution testing. It supports output signals up to 7000PW/PH for monochrome and color cameras. The introductory description specifies central wedges up to 7000PW/PH and corners up to 4000PW/PH, with added low-contrast slanted edges for precise SFR measurement. The detailed description again states support for 7000PW/PH signals, while specifying central wedges up to 4000PW/PH and corner wedges up to 4000PW/PH, together with the low-contrast slanted edges. Select chart size according to FOV, camera pixel count and shooting distance. The manufacturer's RIQA software is recommended for wedge and slanted-edge testing. The chart is made of relatively soft stiff paper, making unsupported positioning and storage inconvenient; mounting attaches a rigid board to the back for easier test positioning.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
