Abstract
A measurement assembly includes a first light emitter set including a plurality of light emitters arranged at equal intervals in a first direction, the light emitters emitting lights with frequencies different from one another; a light receiver disposed on an object under measurement and configured to receive incident lights from the light emitter set; and a position determination unit configured to determine a first current position of the object under measurement according to frequencies of incident lights currently received by the light receiver from the first light emitter set.
Claims17
A measurement assembly comprising:
- a first light emitter set comprising a plurality of light emitters arranged at equal intervals in a first direction, the plurality of the light emitters emitting lights with frequencies different from one another, the light emitted by each of the plurality of the light emitters comprises light of a single frequency or light of multiple frequencies;
- a light receiver disposed on an object under measurement and configured to receive incident lights from the first light emitter set;
- and
- a position determination unit configured to, according to frequencies of incident lights currently received by the light receiver from the first light emitter set, determine which light emitter, of the plurality of light emitters in the first light emitter set, emitting the incident lights, and then determine a first current position of the object under measurement according to position of determined light emitter emitting the incident lights,
- wherein the emitted light from each of the plurality of light emitters is configured to form a light ring at the light receiver;
- and the measurement assembly further comprises:
- a length determining module configured to determine a length of the object under measurement in the first direction according to a number of light rings formed in the light receiver at the same time.
A positioning system, comprising a measurement assembly, the measurement assembly comprising:
- a first light emitter set comprising a plurality of light emitters arranged at equal intervals in a first direction, the plurality of the light emitters emitting lights with frequencies different from one another, the light emitted by each of the plurality of the light emitters comprises light of a single frequency or light of multiple frequencies;
- a light receiver disposed on an object under measurement and configured to receive incident lights from the first light emitter set;
- and
- a position determination unit configured to, according to frequencies of incident lights currently received by the light receiver from the first light emitter set, determine which light emitter, of the plurality of light emitters in the first light emitter set, emitting the incident lights, and then determine a first current position of the object under measurement according to position of determined light emitter emitting the incident lights,
- wherein the emitted light from each of the plurality of light emitters is configured to form a light ring at the light receiver;
- and the measurement assembly further comprises:
- a length determining module configured to determine a length of the object under measurement in the first direction according to a number of light rings formed in the light receiver at the same time.
