摘要： Apparatus and method for providing a three-dimensional image of an ocular retina (R). A source of light (S) flashes illumination on the examined eye (11) wherefrom reflected light is returned. The reflected light carries a first reflection returned from the cornea (CRN) and from the lens (LNS) and a second reflection returned from the retina (R). A fast gate (G) remains closed to block the first reflection and is opened for passage of the second reflection onto a detector (53), via s Shack-Hartmann device (35). Data derived by the Shack-Hartmann device is forwarded to a processing unit (55) coupled to the detector. The Shack-Hartmann device is then used in the conventional way to provide eye aberrations measurements, which are used to correct the second reflection. After eye-aberration correction, the second reflection is the net reflection from the retina. Illumination at different wavelengths permits to map corresponding layers of the retina.

摘要： A method for determining a distance to a target object includes transmitting light pulses to illuminate the target object and sensing, in a first region of a light-sensitive pixel array, light provided from an optical feedback device that receives a portion of the transmitted light pulses. The feedback optical device includes a preset reference depth. The method includes calibrating time-of-flight (TOF) depth measurement reference information based on the sensed light in the first region of the pixel array. The method further includes sensing, in a second region of the light-sensitive pixel array, light reflected from the target object from the transmitted light pulses. The distance of the target object is determined based on the sensed reflected light and the calibrated TOF measurement reference information.
