dc.description.abstract	The imaging element of the 4-element TACTIC telescope array has been in operation at Mt. Abu since 1997, for carrying out detailed investigations of gamma-ray sources in the TeV energy range. In order to characterize the progenitor particle (gamma-ray / cosmic ray), a relative gain calibration system, based on a high intensity LED, has been in operation. However, for calorimetric purposes, an absolute gain calibration system is necessary and has been developed for on-line calibration of 4 out of 349- pixels of its imaging camera, using Am241 -based light pulsers. The details of the scheme followed and the results obtained so far are presented in this paper.	en
