Title: Interferometer using a diffraction grating
IPC: G01B9/02
Filed: 1961-03-08
Abstract: 914,038. Interferometers; refractometers. BAUSCH & LOMB Inc. March 8, 1961 [May 13, 1960], No. 8438/61. Class 97 (1). [Also in Group XIX] An interferometer comprises a diffraction grating for receiving collimated light and dividing the light so received into two divergent beams, reflection means spaced from said grating for reflecting said divergent beams back toward said grating for recombination by the grating into a single return beam and means for observing interference effects in the return beam. The interferometer shown in Fig. 1 comprises a diffraction grating 10 which receives collimated light from a source 12 and produces divergent diffracted beams 18, 20 which respectively pass through test and reference specimens 30 and 32 before being reflected back by reflecting gratings 22, 24 or plane mirrors. The return beams are recombined at the grating 10 and an interference pattern is formed in the image plane 28 where it may be observed. By counting the fringes in the image plane 28 the refractive index of the test specimen 30 may be measured. The reflecting gratings 22, 24 are parallel to the grating 10 and each has half the line spacing of the grating 10. In another form, transmission gratings are provided in the path of each divergent beam 18, 20 before it reaches the specimen so as to render these beams parallel, in this case a single plane mirror being provided for returning the beams along their parallel paths. In order to measure the variations in thickness of a workpiece, the latter may be used to reflect the divergent beams back to the diffraction grating 10. Further, parallelism of the initially divergent beams may be effected by a single transmission grating 46 as shown in Fig. 4, the beams being reflected back by reflecting specimens 52 and 54; this interferometer is employed to measure the displacement of the specimen 52. In a further form, Fig. 5, the interferometer may be used to measure the flatness of a surface 60 on which a transmission grating 62 (which receives collimated light) and a reflection grating 64 are mounted perpendicularly. In this case, the line spacing of the grating 64 is one half that of the line grating 62. Fig. 6 shows yet another form of interferometer in which the light is collimated by a lens 16 and reflected at 76 on to a reflection grating 72 which sends divergent beams to a further reflection grating 64, both gratings being mounted on a surface 60 whose flatness is to be measured.
