An irreversible-reaction measurement method comprising: a step in which a perturbation is applied to one of the divided portions of a measurement sample placed in a light path of a Fourier-transform spectrophotometer to cause an irreversible-reaction while a mirror of the spectrophotometer remains at a data point; a step in which interferogram is detected from the sample portion placed in the path at predetermined time intervals after the application of the perturbation; a step in which the mirror moves to and remains at the next data point after the reaction of the sample portion reaches an end point; a step in which the sample portion placed in the light path is changed to the next sample portion each time the mirror moves to the next data point; and a step in which the irreversible-reaction of the measurement sample is analyzed in accordance with the interferogram obtained by repeating the steps.

Irreversible-reaction measurement method

A method capable of acquiring data at a high speed while holding proper precision during measurement with an infrared imaging apparatus uses an FTIR device of a continuous scan type for detecting a signal by a multi-element detector. A method which acquires data from a multi-element detector in an infrared imaging apparatus. The method involves starting to scan an element of the said multi-element detector synchronously with a sampling signal based on a reference signal of an interferometer, and scanning the element at a higher frequency than a sampling frequency of the sampling signal. The method further involves completing the scanning of all the elements before a next sampling signal to the sampling signal starting the element scanning is generated, and repeating a series of operations every time the sampling signal is generated.

Method of acquiring data from multi-element detector in infrared imaging apparatus

It is an object of the present invention to provide a data acquiring method in an infrared imaging apparatus comprising an FTIR device of a continuous scan type for detecting a signal by a multi-element detector. A method of acquiring data from a multi-element detector in an infrared imaging apparatus comprising the steps of scanning each element of the multi-element detector in order synchronously with a sampling signal () generated by a reference signal () of an interferometer and repeating a series of scanning operations after completely scanning all the elements, thereby carrying out scan, shifting a starting point of sampling in next scan by one element from the starting point of the previous scan, thereby carrying out the same scanning, and repeating the scan at the number of times corresponding to the number of all the elements and then extracting data for each element from storing sampling data, thereby acquiring a data sequence of all the sampling points for each element.
