Reflection gratings are recorded with red (647 . 1 nm) green (514 . 5 nm) and blue (488 . 0 nm) laser light respectively using quasipanchromatic photopolymer plates . The curves of percent transmission versus wavelength and reconstructed wavelength versus exposure for the gratings are given . Using subtractive filters colour reflection holograms are recorded with red green and blue laser light simultaneously. 1. INTRODUCT ION Reflection holograms were invented by Denisyukin 1962 . It has been desired to reconstruct a vivid colour reflection hologram . But there are two difficulties for making it : one is that recording reflection holograms with green and blue light demands high resolution to recording material the other problem is that reconstructed wavelength of a reflection hologram varies with the swell or shrinkage of recording material . Kubotat reported the recording of high qual ity colour reflection holograms with the combination of DCG and si iver halide plates in 1986. Since the study on the photopolymer from 1970 there are many detailed reports on transmission volume hologram. But not until 1985 did R. T. Ingwell and H. L. Fie1ding(Polaroid Company) report the recording of reflection gratings with DtIP-128 photopolymer and they also reported the recording of reflection hologram wit. h DMP-128 in 1986. Photopolymer material is apt to be made as quasipanchromatic . In order to record reflection holograms with homemade photopolymer4 we have separately
