【Abstract】 A new He- Ne laser in which a cat′s eye retroreflector( CER) is used as a moving cavity mirror to replace the plane reflector in plano- concave cavity. The requirement for slide- guide linearity will be decreased and the measuring range will be increased greatly using the novel laser system as a frequency- splitting displacement sensor.Meanwhile,various properties of CER are discussed by means of matrix optics,and the relative theoretical analyses and experimental results are presented.更多还原
