Abstract
Any one or both of an optical system with a structured lighting pattern and a structured detecting system having a plurality of regions with different optical characteristics are used. In addition, optical signals from an object to be observed through one or a small number of pixel detectors are detected while changing relative positions between the object to be observed and any one of the optical system and the detecting system, time series signal information of the optical signals are obtained, and an image associated with an object to be observed from the time series signal information is reconstructed.
Claims31
A method for generating one or more time-independent images corresponding to an object, comprising:
- (a) providing a structured optical pattern comprising a plurality of regions with different optical characteristics and a detector comprising at least a single pixel, wherein said detector is in optical communication with at least said structured optical pattern comprising a plurality of regions with different optical characteristics;
- (b) using said detector to collect optical signals from said object through at least said structured optical pattern while said object is undergoing a change in relative position with respect to said structured optical pattern;
- (c) using said optical signals to generate time series signal data of temporal change in intensity signals generated while said object is undergoing said change in relative position with respect to said structured optical pattern;
- and
- (d) transforming said time series signal data to generate said one or more time-independent images corresponding to said object.
A device for generating one or more time-independent images corresponding to an object, comprising:
- a structured optical pattern comprising a plurality of regions with different optical characteristics;
- a detector comprising at least a single pixel in optical communication with at least said structured optical pattern, wherein said detector is configured to collect optical signals from said object through at least said structured optical pattern while said object is undergoing a change in relative position with respect to said structured optical pattern;
- and
- an image reconstructing unit configured to (i) use said optical signals to generate time series signal data of temporal change in intensity signals genereated while said object is undergoing said change in relative position with respect to said structured optical patterns, and (ii) transform said time series signal data to generate said one or more time-independent images corresponding to said object.
