A flow-cytometer has an excitation light source generating an excitation light that excites one or more bio-cells in a bio-sample carried by a flow path to luminesce. The flow-cytometer includes a spectrum dispersive element that disperses the luminescent light generated by the bio-sample into a photo-detector array. The flow-cytometer further includes a digital signal processor (DSP) that receives signals from the photo-detector array and generates a self-triggering signal based on the luminescent light generated by the bio-cells in bio-sample. The self-triggering signal triggers data capture in the DSP to improve synchronization with the data generated from signals received from the photo-detector array.

Methods and apparatus for self-triggering flow cytometers

A system, an apparatus, and a method are provided for a modular flow cytometer with a compact size. In one embodiment, the modular flow cytometry system includes the following: a laser system for emitting laser beams; a flow cell assembly positioned to receive the laser beams at an interrogation region of a fluidics stream where fluoresced cells scatter the laser beams into fluorescent light; a fiber assembly positioned to collect the fluorescent light; and a compact light detection module including a first image array having a transparent block, a plurality of micro-mirrors in a row coupled to a first side of the transparent block, and a plurality of filters in a row coupled to a second side of the transparent block opposite the first side.
