Depth Sensor

摘要

A depth sensor comprises at least one imaging sensor, at least one multifocal lens, and a focus analyzer. The depth sensor analyzes the in-focus status of electromagnetic radiation, directed by the multifocal lens(es) onto sensing zone(s) of the imaging sensor(s) from spatial zone(s) in a measurement field, to detect the presence of object(s) in the spatial zone(s).

主权项

1. An apparatus, comprising:
a. at least one imaging sensor configured to produce at least one measurement of each of at least two sensing zones; b. at least one multifocal lens configured to direct electromagnetic radiation from each of at least two spatial zones to at least one of the sensing zones; and c. a focus analyzer configured to process each of the at least one measurement to determine an in-focus status of at least one of the sensing zones independent of the other sensing zones.
