Abstract
Provided is a laser scattered light measuring device capable of easily confirming the safety of laser scattered light to a human body. The laser scattered light measuring device includes a light receiving unit, a calculation unit, and a display unit. The light receiving unit receives laser scattered light generated by irradiating an object with laser light and detects intensity of the laser scattered light. The calculation unit compares the intensity of the laser scattered light received by the light receiving unit with a predetermined threshold value and calculates a degree of risk of the laser scattered light to a human body based on a comparison result. The display unit displays the degree of risk calculated by the calculation unit.
Claims13
A laser scattered light measuring device comprising:
- a light receiving unit that receives laser scattered light generated by irradiating an object with laser light and detects intensity of the laser scattered light;
- a calculation unit coupled to the light detecting unit so as to compare the intensity of the laser scattered light detected by the light receiving unit with a predetermined threshold value and calculates a degree of risk of the laser scattered light to a human body based on a comparison result;
- a display unit coupled to the calculation unit so as to display the degree of risk calculated by the calculation unit;
- a laser pointer that points to a generation position in the object of the laser scattered light wherein the light receiving unit is directed by the laser pointer to the position where the laser scattered light is generated wherein the intensity of the laser scattered light is detected by the light receiving unit;
- an alarm unit that issues an alarm sound when the degree of risk is equal to or more than a reference value determined based on the threshold value;
- and
- wherein the light receiving unit includes a lens that concentrates the laser scattered light, a light dimming unit that adjusts a frequency component of light transmitting through the lens to selectively transmit a wavelength of the laser light, and a light sensor that outputs a light intensity signal corresponding to intensity of light transmitting through the light dimming unit to the calculation unit.
