Title: Lens optical performance measuring device
Inventor: WATABE SHIGEO
IPC: G01M11/00
Filed: 1990-11-30
Abstract: PURPOSE:To prevent generation of errors due to a path from occurring by utilizing an interference in real time due to holography for shifting a light flux sideways for interference. CONSTITUTION:Rays which are emitted from a laser 1 are divided into two parts by a beam splitter 3. A light flux which is transmitted through a lens to be measured 8 is projected on a photographic plate for hologram 9. Rays which are reflected by the splitter 3 are introduced into a single-mode fiber 12. An injection edge is fixed at a table 25, thus resulting in a reference light 15 for an object light 27. Interference fringes which are generated by a light 27 and a light 15 in this state are recorded on the photographic plate 9. Then, it is shifted by a small amount for the light 27 so that a space relationship between the photographic plate 9 and the light 15 may not be broken and the resultant interference fringes are recorded on the photographic plate 9. By returning it to its original position after performing development treatment, the interference fringes produced by the light 15 are converted into electrical signal by a CCD camera 17. This signal is taken into a microcomputer and is subjected to calculation processing for allowing a wave surface aberration of a lens to me measured to be obtained, thus enabling a device to be simple and achieving a great effect against vibration.
