Design of Low-Noise Thermoelectrically-cooled Photodiode Array Detector and its Performance in Spectrum Analysis

摘要

Photodiode Array (PDA) detector is a key component of Optical Multiple Analyzer (OMA). The present paper reported the design of low-noise thermoelectrically-cooled Photodiode Array detector and its performance test and analysis in practice. It shows that our designed PDA detector has the advantages of small size, low noise and constant temperature etc., and settles for the demands of high precision spectrum analysis.
