Abstract

A method of imaging a fluorescent sample includes the steps of: scanning fluorescent points of the sample using a scanner apparatus, thereby obtaining scanned fluorescent points; and imaging the scanned fluorescent points on a display, the scanning including the steps of predefining a scan field for the sample, which includes a set of scannable fluorescent points; and sequentially irradiating, at least one first subset of points of the set of points and at least one second subset of the set of points, which complements the first subset with respect to the set of points. The first and second subsets can be irradiated at different focal irradiation distances.

Claims

1. An image forming method of a fluorescent sample comprising the steps of:

detecting fluorescent points (9, 11) of said sample by a detecting apparatus (10, 8A, 8B), obtaining therefrom detected fluorescent points; and

forming images of said detected fluorescent points on a display (12);

wherein the step of detecting comprises;

pre-defining a scanning field (2) of said sample, which comprises a set of fluorescent detectable points (9, 11);

irradiating statically in a first initial step at least a first sub-set of first points (9) of said set of detectable points by a first irradiating beam (8A) generated by an irradiation device (10);

resetting said irradiation device (10) to generate a second irradiating beam (8B) different from said first irradiating beam (8A);

irradiating statically in a subsequent irradiation step at least a second sub-set of second points (11) of said set of detectable points by said second irradiating beam (8B) generated by said reset irradiation device (10), which are different from said first points (9) and that form said set of detectable points when added to said first sub-set; and

completing an image on said display (12) by supplementing reciprocally said first sub-set and second sub-set of detected points.

2. The image forming method as claimed in claim 1, wherein said first irradiating beam comprises a first beam (8A) of detecting laser rays which define a first detecting net comprising said first sub-set of points and said second irradiating beam comprises at least a second beam (8B) of detecting laser rays which define a second detecting net comprising said second sub-set of points, said first beam (8A) of detecting laser rays and said second beam (8B) of detecting laser rays being generated by said irradiating device (10).

3. The image forming method as claimed in claim 1, wherein said irradiating device comprises a spatial light modulator (10).

4. The image forming method as claimed in claim 1, wherein said step of irradiating comprises irradiating said first sub-set at a first focal irradiation distance (P1) with respect to said sample and to irradiate said second sub-set at a second focal irradiation distance (P2) with respect of said sample, different from said first distance (P1).

5. The image forming method as claimed in claim 1, wherein said first sub-set and second sub-set are reciprocally supplemental with respect of said set of detectable points.

6. An image generating apparatus of a fluorescent sample, comprising:

a source (5) of a detecting ray beam (4); and

a spatial light modulator 810) equipped with a phase modulator, designed to modify a phase of said detecting ray beam (4) into at least a first beam (8A) of detecting sub-rays of a first sub-set of detectable points (9) and into a second beam (8B) of detecting sub-rays of a second sub-set of detectable points (11) of said sample.
