A technique for simultaneous measurements of optical birefringence (OB)
and linear dichroism (LD) with a high-accuracy computerized polarimeter
is developed and applied to Ca3Ga2Ge4O14 :Cr3+ crystals. A characteristic
behaviour of equi-intensity ellipses on the HAUP maps is found out. Temperature
dependences of the OB changes and the LD are obtained for the temperature
interval 295–353 K.
Key words: optical birefringence, dichroism, polarimeter, HAUP map
