Abstract
A detector () for determining a position of at least one object is proposed. The detector () comprises: —at least one angle dependent optical element () adapted to generate at least one light beam () having at least one beam profile depending on an angle of incidence of an incident light beam () propagating from the object () towards the detector () and illuminating the angle dependent optical element (), wherein the angle dependent optical element () comprises at least one optical element selected from the group consisting of: at least one optical fiber, in particular at least one multifurcated optical fiber, in particular at least one bifurcated optical fiber; at least one diffractive optical element; at least one angle dependent reflective element, at least one diffractive grating element, in particular a blaze grating element; at least one aperture stop; at least one prism; at least one lens; at least one lens array, in particular at least one microlens array; at least one optical filter; at least one polarization filter; at least one bandpass filter; at least one liquid crystal filter, in particular a liquid crystal tunable filter; at least one short-pass filter; at least one long-pass filter; at least one notch filter; at least one interference filter; at least one transmission grating; at least one nonlinear optical element, in particular one birfringent optical element; —at least two optical sensors (), wherein each optical sensor () has at least one light sensitive area (), wherein each optical sensor () is designed to generate at least one sensor signal in response to an illumination of its respective light-sensitive area by the light beam () generated by the angle dependent optical element (); at least one evaluation device () being configured for determining at least one longitudinal coordinate z of the object () by evaluating a combined signal Q from the sensor signals.
