Abstract: A ptychography system is presented for imaging an object located in an object plane. The ptychography system comprises an optical system, and a detection device. The optical system comprises a single shot ptychography arrangement configured and operable to create light response patterns from the object in the object plane on a pixel matrix of the detection device during the same exposure session of the detection device, wherein the optical system further comprises at least one light coding device configured and operable to apply at least one predetermined coding function to at least one of illuminating light and the light response of the object being collected, and said detection device is configured and operable with a predetermined duration of the exposure session during which the pixel matrix detects the collected light, such that image data indicative of the detected light during a single exposure session is in the form of a coded light response of the object being illuminated.

Abstract: A method comprising: receiving a plurality of signals representing spectral emissions resulting from an interaction between a laser field and a respective plurality of analytes, wherein at least some of the analytes comprise multi-center chiral molecules; at a training stage, training a machine learning model on a training set comprising: (i) the plurality of signals, and (ii) labels associated with a configuration of a chirality in each of the plurality of analytes; and at an inference stage, applying the machine learning model to a target signal representing spectral emission associated with a target analyte comprising a multi-center chiral molecule, to determine chiral characteristic of the target analyte.

Abstract: A method for directing non-modulated light from a Spatial Light Modulator (SLM) and allowing through modulated light for producing an interference based holographic image, the method including illuminating the SLM with coherent light, thereby producing a mix of light modulated by the SLM and light not modulated by the SLM, and projecting the mix of the modulated light and the not modulated light along an optical axis onto a volume grating, wherein the volume grating directs the not modulated light away from the holographic image and allows through modulated light for producing the holographic image. Related apparatus and methods are also described.
