Light pulse signal processing system comprising a cylindrical lens to provide a signal light pulse having a spatial angle chirp incident on a pair of long mirrors at different angles

A light pulse signal processing system, comprising:

• a reference signal light source configured to generate a cluster of reference light pulses having a first repetition rate, a beam combining mirror, a to-be-measured signal light source, a cylindrical lens, and a pair of long mirrors;
• wherein,
• the to-be-measured signal light source is configured to generate a to-be-measured signal light pulse and transmit the to-be-measured signal light pulse to the cylindrical lens;
• the cylindrical lens is configured to convert the to-be-measured signal light pulse into a to-be-measured signal light pulse having a spatial angle chirp, so that the to-be-measured signal light pulse having the spatial angle chirp is incident on the pair of long mirrors at different angles;
• the pair of long mirrors is configured to delay the to-be-measured signal light pulse incident at different angles by means of inter-mirror reflection, and to output a cluster of to-be-measured signal light pulses having a second repetition rate to the beam combining mirror;
• wherein a rate difference between the second repetition rate and the first repetition rate is less than a set rate difference threshold;
• and
• the beam combining mirror is configured to combine the cluster of to-be-measured signal light pulses with the cluster of reference light pulses generated by the reference signal light source, for a light signal analysis device to analyze the combined cluster of light pulses.
