Miniature linear sliding platform with displacement measurement function

The invention relates to the technical field of medical instruments, and discloses a miniature linear sliding platform with a displacement measurement function. The miniature linear sliding platform comprises a guide sliding rail, a sliding platform, a driving assembly and a light curtain type distance sensor. The light curtain type distance sensor is arranged on the sliding platform, an inclined plane and/or an inclined groove monotonically changing in the axial direction are/is formed in the side, facing a light curtain emitted by the light curtain type distance sensor, of the positioning guide shaft, the overall structure is compact, measurement precision is high, reliability is good, and miniaturization and precise control of equipment are facilitated. When the sliding platform moves from the first position to the second position, first measurement calculation and/or second measurement calculation are/is carried out according to the corresponding relation between the change of the distance measurement val
