APPLICATION OF COMPUTER ISOPHOTOMETRIC METHOD IN INTERFEROMETRY
Annotation
The problem of increasing the accuracy of interference measurements is solved by selecting the lines of the centers of interference bands – isophots. The interferogram can be obtained, for example, using a Linnik micro-interferometer. The principles of isophotometry used in computer processing of interferograms are considered. Isophotometry is based on the use of an image receiver – analyzer that performs interference image conversion with the implementation of the comb-type conversion function. Due to the use of this transformation, an increase in the accuracy of interference measurements by a factor of 5–10 is achieved.
