In a previous publication �Jellison and Modine, Appl. Opt. 36, 8190–8198 �1997��, three points ofinformation were presented inaccurately. These inaccuracies are corrected here. © 2003 OpticalSociety of America
OCIS codes: 120.2310, 120.6200, 230.5440, 260.1180, 260.2130, 260.5430.
The signs in the Eqs. �16�, �21�, and �23� of Ref. 1needed to be corrected. This results in the followingequations.
1. Change the sign of the IY0X1 term in Eqs.�16a�–�16d�.
Case I: �m0 � �45° and �m1 � �45°
M � �Idc �0sIY0 � IX0
�1sIY1 �0s1sIY0Y1 � �1sIX0Y1
� � � �
IX1 �0sIY0X1 � IX0X1
� . (16a)
Case II: �m0 � �45° and �m1 � 0°, 90°
M � �Idc �0sIY0 � IX0
� � � �
�1cIY1 �0s1cIY0Y1 � �1cIX0Y1
IX1 �0sIY0X1 � IX0X1
� . (16b)
Case III: �m0 � 0°, 90°; �m1 � �45°
M � �Idc � �0cIY0 IX0
�1sIY1 � �0c1sIY0Y1 �1sIX0Y1
� � � �
IX1 � �0cIY0X1 IX0X1

2. Change the sign of the imaginary component ofthe matrix A �Eq. �21�� resulting in
A � �1 0 0 11 0 0 10 1 1 00 i i 0

3. Change the sign of 2 and �2 in Eqs. �23l� and�23n�, resulting in
2 � �D�2��CspSps � SspCps�, (23l)
�2 � �D�2��CSps � SCps�. (23n)
