Interferometrisches Spektrophotometer. |
摘要 |
<p>There is disclosed an interference spectrophotometer which collects data while monitoring the position of a movable mirror by providing quadrature control to accurately perform coherent addition of data. The spectrophotometer includes a main interferometer (100), a control interferometer (12), a sliding controller (20) controlling movement of the movable mirror (6), an A/D converter (47) converting analog data obtained by the main interferometer into digital form, a register (106) for holding data obtained by one scan of the movable mirror, a memory (108) for accumulating data obtained by numerous scans of the movable mirror, an up/down counter (82) receiving the output signals from two detectors included in the control interferometer, and a decision part (110). When the counter's value varies, the counter causes the A/D converter to perform its A/D conversion. Then, the decision part checks the counter's value after the A/D conversion. If this value differs from the count value obtained prior to the A/D conversion, the data held in the register is discarded.</p> |
