Patent ID: 8807801

Claim:
An endoscopic device for illuminating a sample over a 3-dimensional volume, the device comprising: a connector stage for receiving an input beam of short pulses; an xy-scanning stage coupled to receive the input beam of short pulses and scan the short pulses for movement in a lateral direction across an xy-plane of the sample; an actuator stage coupled to scan the short pulses for movement in a z-axis direction of the sample, where the actuator stage comprises a piezoelectric stage capable of producing a first displacement, an amplification stage mechanically coupled to the piezoelectric stage for amplifying the first displacement into a second displacement, and a lens mounting stage coupled to the amplification stage, where the piezoelectric stage, the amplification stage, and the lens mounting stage form an integrated MEMS assembly; and a lens mounted on the lens mounting stage for scanning the input beam across the 3-dimensional volume within the sample.
