Abstract: The invention relates to a Handheld Biophotonic Medical (HBM) device for multimodal and multispectral imaging of a tissue. The HBM device comprises a hardware switch that provides trigger pulses to control unit of the HBM device, which controls an illumination unit to illuminate the tissue. Further, HBM device controls a miniature monochrome imaging device to stream live video image of tissue fluorescence and to capture images of tissue fluorescence and diffusely reflected light in real-time based on the light of specific wavelengths received from a collection optics unit upon illumination of the tissue. The control unit transmits the captured images to a computing device that determines grade of cancer and inflammation by analysing the captured images. The HBM device is light weighted, portable, can be inserted into body parts such as oral cavity, cervix and can also be mounted on endoscopes to examine internal organs of body.

Abstract: Embodiments of the present disclosure provide a photocoagulation device and a method to produce a light beam of a predefined wavelength using the photocoagulation device. The device comprises at least one light source, non-imaging light collimator (NILC), at least one first and second condenser, a ball lens and at least one galvo-mirror. The light source is one of light emitting diode (LED) and organic LED (OLED), which emits light of a predefined wavelength. The NILC collimates the light emitted by the at least one light source, the at least one first condenser produces a focused light beam using the collimated light. The at least one second condenser produces light spots, with a diameter in terms of microns, using the focused light beam from the at least one first condenser. The ball lens collimates the light spots, which is steered by the galvo-mirror to focus on a target area.
