Disclosed are photonic particles and methods of using particles in biological samples. The particles are configured to emit laser light when energetically stimulated by, e.g., a pump source. The particles may include a gain medium with inorganic materials, an optical cavity with high refractive index, and a coating with organic materials. The particles may be smaller than 3 microns along their longest axes. The particles may attach to each other to form, e.g., doublets and triplets. The particles may be injection-locked by coupling an injection beam into a particle while pumping so that an injection seed is amplified to develop into laser oscillation. A microscopy system may include a pump source, beam scanner, spectrometer with resolution of less than 1 nanometer and acquisition rate of more than 1 kilohertz, and spectral analyzer configured to distinguish spectral peaks of laser output from broadband background.

A compact, portable Raman spectrometer makes fast, sensitive standoff measurements at little to no risk of eye injury or igniting the materials being probed. This spectrometer uses differential Raman spectroscopy and ambient light measurements to measure point-and-shoot Raman signatures of dark or highly fluorescent materials at distances of 1 cm to 10 m or more. It scans the Raman pump beam(s) across the sample to reduce the risk of unduly heating or igniting the sample. Beam scanning also transforms the spectrometer into an instrument with a lower effective safety classification, reducing the risk of eye injury. The spectrometer's long standoff range automatic focusing make it easier to identify chemicals through clear and translucent obstacles, such as flow tubes, windows, and containers. And the spectrometer's components are light and small enough to be packaged in a handheld housing or housing suitable for a small robot to carry.

A wide-angle camera comprises a spectroscopic module, a first imaging module, and a second imaging module. The spectroscopic module comprises a spectroscopic lens holder, a first optical prism, and a second optical prism. The first optical prism is disposed on a first sidewall of the spectroscopic lens holder. The second optical prism is disposed on a second sidewall of the spectroscopic lens holder. The first sidewall is opposite to the second sidewall. An external light is split into a first light and a second light correspondingly through the first optical prism and the second optical prism. The first imaging module corresponds to the first optical prism and receives the first light for generating a first image. The second imaging module corresponds to the second optical prism and receives the second light for generating a second image. The first image and the second image are synthesized into a wide-angle image.

At least one of the pixel lines is an imaging line designated for acquiring at least one image of an object and other of the pixel lines are spectral measurement lines designated for acquiring a spectral measurement of light received from the object.

An imaging system that includes a digital micromirror device (DMD) and a tunable filter, wherein the imagining system applicable for Raman imaging, can fluorescent imaging, phosphorescent imaging, photoluminescent imaging, all of which require excitation of a specimen at a particular wavelength and analyzing the reflected light from the specimen at a wavelength that is different from the excitation wavelength, so called inelastic light scattering—ILS. A reconfigurable DMD-based inverse, spatially offset Raman spectroscopy (SORS) system is also described. Beneficially, the DMD system in the excitation path provides a uniform intensity over the sample field of view. It is also configured to prevent sample damage. Placement of a second DMD in the return path of light enables selective rejection of light in space to obtain a reconfigurable inverse SORS system that enables collection of information from different layer depths of the sample using a single detector.
