摘要： An observation apparatus is provided. An apex angle of a contact prism is inputted by operating an apex angle setting knob of a control panel. A fining angle of the contact prism is inputted by operating a fitting angle setting knob. A control unit determines the amount of correction for astigmatism of a left observation optical system and the amount of correction for astigmatism of a right observation optical system based on a recognized observation magnification and the inputted apex angle. An axial angle for the astigmatism of the left observation optical system and an axial angle for the astigmatism of the right observation optical system are determined based on the inputted fitting angle. Variable cross cylinder lens rotating drive units are controlled to rotate cylinder lenses of each of the right and left observation optical systems, thereby obtaining the determined axial angle and the determined amount of correction.

摘要： Provided is an optical image measuring apparatus capable of taking images of an object to be measured in plural depth regions in parallel. An optical image measuring apparatus of the present invention includes: a beam splitter (4) for dividing a light beam into signal light (S) and reference light (R); beam splitters (5-1 to 5-(n−1)) for dividing the reference light (R) into plural reference light beams (R1 to Rn); frequency shifters (6-1 to 6-n) for shifting frequencies of the reference light beams (R-1 to Rn) by different amounts; and reflector plates (7-1 to 7-n) arranged at different distances from an object to be measured (O). The reference light beams (R1 to Rn) and the signal light (S) reflected by the object to be measured in depth regions (D1 to Dn) are superimposed on each other to thereby produce interference light (L). Shutters (9-1 to 9-3) extract interference light components (L1 to Ln) from the reference light (L), and CCD cameras (10-1 to 10-3) receive the interference light component and convert the interference light component into electrical signals to output the signals. A computer (20) forms images in depth regions corresponding to the interference light components based on the electrical signals.
