摘要： A device for measuring a characteristic of an optical element which forms an interference fringe pattern using a reference light beam reflected from a reference surface and a test light beam that is guided from the optical element by a light refracting element. The interference fringe pattern is detected and data corresponding to the interference fringe pattern is output. The outputted data is processed such that information of wave front aberration representative of the interference fringe pattern is output. The information includes mathematical terms representative of position errors and of the characteristic of the optical element. The mathematical terms are calculated, and the mathematical terms representative of the characteristic of the optical element are corrected based on a value of at least one of the mathematical terms representative of the position errors. The corrected mathematical terms are then displayed.

摘要： A device including a polarizing beam splitter by which an incident luminous flux is split into a first luminous flux radiated onto a first photo sensor and a second luminous flux radiated onto a second photo sensor, and an adjusting mechanism provided for adjusting a position of one of the first and second luminous fluxes. The optical axis of the first luminous flux is coincident with that of the incident luminous flux. The optical axis of the second luminous flux is not parallel to the first luminous flux. By moving the beam splitter along the optical axis of the first luminous flux, the beam receiving position of the second photo sensor, onto which the second luminous flux is radiated, is changed.

摘要： An interferometer causes a reference beam and a subject beam reflected from a roof surface to interfere with each other to form an interference fringe, which is detected by an image detecting element in its measuring area. Detection data from the image detecting element is processed by an image processing circuit, and then subjected to phase difference detection. A continuous function is determined as an approximation to a relationship between phase data and unit measuring areas located in a direction perpendicular to a line corresponding to a ridge line of the roof surface. A analysis relating to a roof angle is performed based on the continuous function thus determined.
