OPTICAL DETECTION APPARATUS WITH MEANS FOR SELECTING AN OPTICAL DETECTOR AND/OR A DETECTOR AMPLIFIER

摘要

Optical detection apparatus (300) comprising an optical detector (302, 304, 306), a detector amplifier (336, 338, 340), and switching means, e.g., a multiplexer (344, 348), for dynamically selecting at least one of the optical detector or the detector amplifier by switching from among at least two alternative optical detectors and/or at least two detector amplifiers such as to minimize noise equivalent power (NEP) of a selected detector or combination of detector and amplifier under given operating conditions.
