Title: Beam enlarging optical system for position detecting sensor
Inventor: TASHIRO KATSU
IPC: G01B11/00
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To correct the deviation of light quantity distribution and detect an accurate optical axis position by dividing luminous flux incident on a position detecting element (PSD) into two by a beam splitter, in an optical system using PSD, composing the beams again after passing mutually different optical path length, and making the composed beam incident on the PSD. SOLUTION: The light emitted from a light source 1 is irradiated to an object through a lens 2. The reflected light from the object 3 is incident on a non-polarizing beam splitter 6a through an imaging lens, by which about 50% of the total light quantity is reflected, and the remainder is transmitted. The reflected light is reflected by total reflecting mirrors 6c, 6d, and incident on the non-polarizing beam splitter 6b, and about 50% of this is further reflected and incident on a PSD 5. On the other hand, the transmitted light by the beam splitter 6a is incident directly on the beam splitter 6b, and about 50% of the light quantity is transmitted and incident on the PSD 5.  Since both the reflected light and the transmitted light are incident with a deviation between the imaging point and the PSD surface, the beam diameter when incident on PSD is fuzzy, and non-linear of response by throttling to a minute point is never caused.
