Abstract
In one embodiment, an apparatus includes a first stage and a second stage. The first stage may include a micro light-directing unit that is operable to receive a light beam from a light source and direct the light beam along one dimension to discrete input locations of a second stage. The second stage may be operable to receive the light beam from the first stage at the discrete input locations along the one dimension and direct the light beam through two dimensions to discrete output locations of the second stage to scan a three-dimensional space.
Claims18
An apparatus comprising:
- a first stage that comprises a grated-light valve (GLV) that is operable to:
- receive a light beam from a light source;
- and
- direct the light beam along one dimension to discrete input locations of a second stage;
- and
- the second stage, operable to:
- receive the light beam from the first stage at the discrete input locations along the one dimension;
- and
- direct the light beam through two dimensions to discrete output locations of the second stage to scan a three-dimensional space.
A method comprising:
- at a first stage that comprises a grated-light valve (GLV):
- receiving a light beam from a light source;
- and
- directing the light beam along one dimension to discrete input locations of a second stage;
- and
- at the second stage:
- receiving the light beam from the first stage at the discrete input locations along the one dimension;
- and
- directing the light beam through two dimensions to discrete output locations of the second stage to scan a three-dimensional space.
An apparatus comprising:
- means for receiving at a first stage a light beam from a light source;
- means for directing the light beam along one dimension to discrete input locations of a second stage;
- means for receiving the light beam from the first stage at the discrete input locations along the one dimension;
- and
- means for directing the light beam through two dimensions to discrete output locations of the second stage to scan a three-dimensional space.
