Anti-jamming Design for External Circuit of Pyroelectric Detector
By researching external circuit of pyroelectric detector in a laser spot measurement system, combining the operating principle of pyroelectric detector, the factors interfering the measurement system were analyzed and an anti-jamming external circuit of the pyroelectric detector was designed. The test shows that this circuit can reduce the optical interference in thermoelectric conversion, and increase the signal output amplitude and signal to noise ratio. The measurement accuracy of this system is improved.
