The present invention discloses a multi-lightpath and multi-angle measurement apparatus, including an electrically controlled rotary table, electronically controlled translation tables, a laser transmitting/receiving end face, laser couplers, a multipath data acquisition card, a laser controller, a translation controller, an etalon, a laser, detectors, and a computer. The measurement apparatus uses an all-fiber coupling structure, and two ends of the laser transmitting/receiving end face are respectively fixed on two electronically controlled translation tables. Therefore, a maximum area measured by the apparatus is 350 mm×350 mm, and an adjustable minimum translation distance is 1 mm. Bottoms of the translation tables are fixed on the electrically controlled rotary table. Featuring an ingenious design and a compact structure, the whole apparatus is easy to disassemble and easy to operate. The apparatus has high universality, and can implement two-dimensional measurement in a high-temperature combustion flow field.
