Abstract

The invention discloses the field of dynamic characteristic research for interaction of laser and atmosphere in spectrum detection for trace gas and free-space optical communication, and particularly relates to an automatic tunable system with multiple optical paths. The automatic tunable system comprises angle rotating devices, length adjusting devices, supports, motor supports, stepper motors, a DSP (digital signal processor) controller and a cylindrical main body. The main body can keep vacuum and can bear certain high pressure. Signals are inputted into the DSP controller according to requirements of the optical paths, rotational angles of concave reflectors and required voltage are computed by the DSP controller, piezoelectric transistors (PZT) can drive the concave reflectors to rotate by the rotational angles after being supplied with the required voltage, signals are outputted for triggering and driving to realize automatic angular rotation, simultaneously, the stepper motors are driven, corrugated pipes are driven to stretch or contract, and distances d among reflecting pools are horizontally increased or reduced. The automatic tunable system with the multiple optical paths has the advantages of high precision and sensitivity, simplicity in operation and automatic control function.

Description

technical field [0001] The invention relates to the research field of the dynamic characteristics of laser-atmosphere interaction in trace gas spectral detection and free-space optical communication, in particular to an automatically tunable multi-optical path system. Background technique [0002] Multi-pass cells can be roughly divided into resonant multi-pass cells and non-resonant multi-pass cells. The adjustment of the resonant multi-path cell is more complicated and has higher requirements on the light source, and it is necessary to ensure that the light and the multi-path cell resonate strictly during the measurement, so it is not very convenient in practical application. The simplest non-resonant multi-path path cell can be realized by two plane mirrors, such as the patent application number: 201110131656.3 A gas absorption cell for absorption spectrum measurement, which increases the absorption optical path through two plane mirrors and improves the spectrum Determi...
