The embodiments of the present application relate to the technical field of aerosol generation apparatuses. Disclosed are a color testing calibration method and an aerosol generation apparatus. The method comprises: acquiring a no-load signal of an aerosol generation apparatus, then controlling a color testing apparatus to perform a color test, so as to obtain a new background color value; according to the new background color value and the current background color value, calibrating the current color threshold interval, so as to obtain a new color threshold interval; and storing the new color threshold interval and the new background color value. That is, along with the use of an aerosol generation apparatus, the current background color value and the current color threshold interval are re-calibrated, a new color threshold interval and a new background color value, which are obtained by means of calibration, are used as reference values for color determination, such that the reference values are adapted to a smudge and aging of a color testing apparatus. By means of the present application, fine errors such as small dirt and brightness attenuation can be corrected in a timely manner, color testing is more accurate, and the anti-dirt effect is effectively achieved.

This utility model provides a color testing device for automotive ambient light guides, comprising: a base plate, with wheels at the bottom of the base plate, a testing device housing at the top of the base plate, a storage cabinet at the bottom of the testing device housing, a workbench in the middle of the testing device housing, a support frame on the workbench, clamping parts on both sides of the support frame, and a light-shielding part and a testing part above the workbench. The color testing device for automotive ambient light guides provided by this utility model features a central support frame that enhances the stability of the main support structure. The arc-shaped pads of the contact pads and clamping parts, combined with springs, provide flexible clamping to avoid damage to the light guide strip. The light-shielding part uses a staggered adjustment through light-transmitting holes for precise light control. Combined with the testing part, a three-dimensional positioning system formed by a first sliding rail, a crossbar, and a lifting push rod expands the detection range of the detection probe, testing the detection effect at various locations and improving efficiency.

This document discloses a phototherapy device and related systems and methods having features for determining a user's dosage regimen. In some embodiments, the phototherapy device may include a colorimetric testing component positioned to acquire measurement data of a treatment area on a user's skin. The phototherapy device may use this measurement data to calculate the average Individual Type Angle (ITA) of the user's skin across the entire treatment area and use the average ITA to determine a dosage regimen tailored to the user's skin characteristics. The phototherapy device then irradiates the treatment area with a specific dose of ultraviolet radiation according to the dosage regimen.
