Abstract:
Circular dichroism can be accurately measured even when a phase modulation element with a distortion component is used. A circular dichroism measuring method using a circular dichroism measuring device  2  includes a step of measuring Ip(t) (S 101 : phase amount change acquisition step), a step of measuring Is(t) (S 102 : sample data acquisition step), a step of converting Ip(t) to δ(t) (S 103 : phase amount change acquisition step), a step of converting Is(t) to Is(δ) (S 104 : analysis step/Is(δ) calculation step), and a step of performing curve fitting to calculate matrix elements S 00 , S 02 , and S 03  (S 105 : analysis step/matrix element calculation step).

Claim (Index 4):
