dc.description.abstract | Details of successful use of a new high speed infrared photometer for recording lunar occultation light curves simultaneously in K (2.2 /..Lm) and L (3.6 fJ.m) bands are presented, The photometer has also a provision to incorporate a CCD in its light path for quick monitoring and positioning of the opticalfIR sources. A motorized nip mirror arrangement for 45° angular movement using stepper motor controlled drive has been put into operation. The change from optical to IR channels can also be triggered by remote control using a radio frequency transmitter-receiver system. Lunar occultation observations of two M3 giants 1) Gem and /..L Gem in K and L bands have been successfully observed. | en |
