The utility model discloses a portable wireless transmission and image display type microorganism fast detection searchlight, which belongs to the fields of biology, medical science, photoelectricity and information technology. The searchlight includes a light source generating means, a light source controlling means, a filter, a beam expanding mirror, a beam splitting mirror, an objective table, a holophote, a beam splitter, a signal intelligence analytical means, a wireless transmission module and a display screen. The light source controlling means comprises a collimation lens, a beam splitting mirror, a photoelectric diode and a control circuit. The output end of an intelligence chip is connected to the input end of the display screen and is also connected to the input end of the wireless module. A numeral hologram is generated through the interference between the sample light and the light passed through surrounding medium. Images, acquired through photosensitive component by users, are more objective, visual and more convenient to observe, moreover, data can be remotely transmitted in real time via the wireless module, preventing the data from losing and rewriting. The searchlight has the advantages of small volume, portable, wide application in various fields and conditions, as well as broad application perspective.
