Abstract

The invention discloses a compact narrow-band background light power meter and laser detection equipment comprising the same. The compact narrow-band background light power meter comprises a lens and a host, wherein the host comprises a detector, a pre-amplifier, a filter, a post-amplifier, an analog-to-digital converter, a microprocessor key, a display screen and an external serial interface which are integrated in a shell of the host; and the host is detachably connected with the lens. The compact narrow-band background light power meter is suitable for detecting and calculating background light power and spectral radiation brightness data in an industrial-grade temperature range, and has the characteristics of small size, high reliability, wide applicable temperature range, simple setting and low operation difficulty.

Description

technical field [0001] The invention relates to the field of measurement of optical power and spectral radiance, in particular to a compact narrow-band background optical power meter and a laser detection device containing the same. Background technique [0002] Laser radar, laser range finder, laser altimeter, laser receiver, laser seeker and other laser detection equipment working in a single wavelength and narrow bandwidth need to calculate the target distance and height by detecting the weak laser echo signal reflected back from the measured target , location and other information. The working spectral range of this type of laser detection equipment is determined by the optical filter components such as band-pass filters used, usually within tens of nanometers. For example, the working wavelength of an industrial laser rangefinder is 905nm, and the spectral bandwidth is 10nm. While receiving the laser echo signal reflected back from the detection target, it will also re...
