摘要： The invention relates to a detector without temperature regulation which comprises a matrix of suspended bolometers arranged in the focal plane of a lens, a reading circuit providing a flow of raw values, and a shutter. A method for correcting raw values comprises: after closing the shutter, a first step (102) of acquiring a common table of raw values; a second step (108) of determining a table of offset corrections for the current temperature of the detector according to the common table and a set of stored tables of raw values; and a third step (60) of correcting the flow of raw values by means of the table of corrections. According to the invention, a maintenance process (122, 103) comprises: testing a condition for replacing a table of said common set with the common table; if said condition is fulfilled, replacing the table of said common set with the common table. The test comprises establishing the existence of a new set of tables, resulting from the replacement of a table of the common set with the common table, which is more relevant than the common set for the purpose of subsequently establishing the offset table.
